Porsche Cayman GT4 MR: A Manual GT4 RS? | Catchpole on Carfection
Вставка
- Опубліковано 28 вер 2024
- The GT4 RS is a spectacular car but it does have its flaws. For starters, it’s very difficult to get hold of one and for all its engagement, it just lacked a manual transmission. This is RPM Technik’s solution: The Porsche 718 Cayman GT4 MR.
If you haven’t already seen Henry’s road trip of the GT4 RS you should head over here: • Porsche 718 Cayman GT4...
How has RPM Technik improved on the already fantastic GT4? Here’s how:
- MR kit by Manthey-Racing
- Upgraded brakes
- New exhaust
- Shorter ratios for the MANUAL gearbox
Why are the shorter ratios in the manual gearbox a much welcomed modification?
Because the standard GT4’s ratios are so tall that the gears rarely need changing. So rarely, that you could reach motorway speeds in second gear! This may sound convenient if you don’t like rowing your own gears but those that buy the manuals want more engagement so it defeats the point. To Porsche’s credit, the lofty ratios are more of a workaround to the ever stricter emissions regulations.
If you’ve never hear of Manthey-Racing, they have been responsible for running Works Porsche Motorsport GT teams since 2013. Porsche now owns 51% of the company, so these road car upgrades have the blessing of the Stuttgart mothership.

For the GT4, DeMan does a bespoke 4.5L engine swap and regears 2-5. It is, not surprisingly, amazing.
As much as I like the Cayman and the idea of performance upgrades: In the end you spend a ton of money on making your Cayman faster. However, you have to face the fact that there will always be someone who is quicker. Always. You might as well go for a more powerful, faster car to begin with. Which will, inevitably take you to the point to find that there is yet another car that is quicker. It is just terrible. Better leave it as it is and spend the money on something else. Driver training, maybe
@@fritzbrause6332 I think the Cayman platform is about a lot more than just putting up numbers and being faster than other cars. It’s an amazing platform that accentuates all of the ‘feels’ of a great sports car. You could potentially have a 4.5L cayman for roughly the same money as a 997 or 991 GT3 and it would be arguably a better driving experience. The platform can handle the power and remain balanced.
@@fritzbrause6332 you are the type of person that thinks having more horsepower means its a better car. No one cares about lap times anymore.
@@fritzbrause6332 The way I think about the 4.5L upgrade for my 981 Spyder is I can have a faster car than the 911Speedster for 1/2 the price.
Until u have issues then no warranty 😢
Please just get to 1 million...
Really I don't normally care about that stuff but you guys really put out the best content. You actually think about what you say, camera shots and more than anything else put forward your passion. It is tangible.
992k is a good number tho ;)
Beautiful video guys, looks like I need to get in touch with MR and RPM Technik for some parts!
Contact Alex Hardt.
You need a DeMan Motorsport engine too.
Not sure if you need to Luke, yours is a PDK and you've done the suspension work and camber. So not much more to mess with. I'd stick with sportec. It's great to see something different. Your also more of an Swiss alpine driver (passes), and not a green hell driver. Having done both types of driving, I'd take the swiss passes anyday! Just my opinion.
@@911aircooled5 Cheers, good feedback 👌🏻 and yes the pdk gear ratio already feels way better than the stock manual.
@@carswithluke But not this MR manual!
Brilliant, Henri's reviews never disappoint ! Probably, if not, the best automotive journalist.
I love the 911, but hate the way it’s had Porsche pulling its punches with the Cayman and Boxster all these years. I hope someone in Stuttgart is watching this…..
Or just make a new mid engine high end platform and make the 911 more of a GT.
@@iceblade019 are we not already there? The 911 is a big machine these days and there is no longer a narrow body variant. And it's so bloody quick! Even these top end cayman models are getting towards being too quick to be useful on the road.
The GTS, GT4 and Spyders in the 718 generation are basically there.
Nein.
Cmon, can we PLEASE get these guys to 1m subs?!?!? They so deserve it.
Like I always say, name a better Duo.. Catchpole and Porsche
Another quality review on a quality car by a Top motoring journalist, ie Catchpole
The GT4 4.0 has circa 420bhp or thereabouts. The GT4 RS 500bhp.
What are the actual technical differences between the 4.0 GT4 engine and the GT3 engine that's in the GT4 RS?
It's a big power difference and I've always wanted to know.
If you want you can dial the KW3 shocks to a more street oriented setup without any problem - all by yourself! It may even be more comfortable than the GT4 standard setup because KW shocks work very good with short impulses (which is the "high speed" setting in the dampers - has nothing to do with the speed of the car). And if you go to the track just redial it to the recommended Manthey setting. Shouldn't require more than 15 minutes for all four wheels.
I was about to comment the same. What is the point of having 3 way (easy accessible) adjustment, if you don't use it? Play arond with it on the road, find a good road setup, write it down, than, find a good track setup, write it down, and after that, you can switch from one to the other easy and quick ;-) It's only a couple of clicks!!
Dream car in a dream spec, thanks Henry!
Fabulous review Henry. Technical and Insightful, yet easy to understand. Thank god I don’t have a GT4… I wouldn’t be able to resist the gear and brake upgrade 😂. But now makes me want to protect the PCCBs on my GT3 by swapping to ST !
I'd watch Henry review a Toyota Camry. Haha! Great as always.
Another great Henry review 💪🏾
There's a low mile 991 GT3 engine on eBay for £16k. I'd opt for that suspension, those carbon brakes and adding the GT3 engine over this RPM conversion.
Car looks and sounds amazing! But is that a tie wrap holding the remote reservoir in place???
If ever a man needed some good advice from their barber its Henry. You look a state fella - like you just got up after having slept for six months!
Manual RS spyder would be nice
Hey, nice work. I'm a fan!
Reducing Unsprung mass is very important especially when you have an inferior suspension design such as McPherson struts.
McPherson struts work just fine in a GT4
McPherson is good for rubbish bumpy roads and harsh concrete roads ect. The GT4 might be 'track focussed' but it's predominantly a road car.
@@johnmitchell2269 every review makes it seem that the gt4 is horrible on rubbish bumpy roads... so idk about all that
@@johnmitchell2269 McPherson is less good than a double A-arm or multilink on harsh surfaces, that's why the 992 GT3 is still faster around the Nordschliefe than the GT4RS, because it has double wishbone front and multilink rear and can thus handle the bumps and such a little better. MacP struts are good for packaging and saving costs.
Even though I criticize MacPherson struts in the other comment, they are still acceptable for a wide variety of cars. All 911s have them up front (with the exception of the aforementioned 992 GT3) as do things like the BMW M3 and M2, and a load of other sports cars.
Thank U, 👏
Humans...never satisfied! A manual standard (plain, non-RS, non-MR...take your pick) GT4 in any spec or gen is the holly grail, no need for less or more. Except you can't buy a brand new standard GT4s anymore...no tears: grab a used one whilst you can as I suspect the available stock will soon turn vapour. And whilst we are here: forget the picky banter about the gears - the box is already a gem in standard gear guise
Proper tuning.
The whole video I was thinking well yes but actually no, it's not the GT3 engine, interesting to see at the end Henry say the exact same thing hahhah
Do we know what the alignment specs are for this?
Nice vdeo
Nice
How would you say the MR compares to the 981 Sharkwerks GT4?
I’ll take the shorter ratios, it’s the one change the std GT4 desperately needs and for just £1200 it’s a bargain.
£1200 is just to add the lightweight flywheel and clutch, and the overdrive 6th gear. The shorter final drive conversion is just under £6500
@@thoho oh thanks, I thought that sounded remarkably cheap. Still worth it though.
That same money gets you a DeMan Motorsport GT4 in the states. Just a BIT better value for money....
exhaust gearbox please. Keep the rest !
The MR is simply perfect besides the gear ratio. Love it to the bone when i'm lapping the Nordschleife. Anyway - gonna swap my GT4MR to a GT4RS end of this season. Still not sure it'll worth the upgrade (besides the engine). The visuals is still not growing on me. Hard times ahead...
Did you get an allocation for a GT4 RS? If not, do you think they are worth €220k+ on the secondary market? Much faster cars for that money if lapping the 'ring is your thing.
@@yetidh9 i got an late 2022 allocation. for 220k i would try to get a GT3 allocation if available without markup. The GT4RS will be a unicorn - so i would go for it if i haven't an allocation. anyway - the GT3 will be the better car...
if I was rich.. this is the car I would buy..
More importantly is not can you get one of these but can you afford one?
HQ content as always.
front grill is shit
Oh I don’t know; ready to be shot to bits, but the “heal and toe” thing is just a hang over from “back in the day” when to get the best performance out of “straight cut” gearboxes with fragile synchromesh it was THE only way to optimise cog swapping. Modern PDK box is just sublime and prevents “ham fisted thugs” like me from trashing the box. Sorry, manuals just don’t give me hard on that so many others (apparently) love to rave about. Rant over 🥸
Nah man, driving a manual is really fun. I drove a manual once and gotta admit it feels really special. However, I still choose the AT for daily tho
If you daily nothing but manuals and get to the point where heel-toe rev-matching when downshifting and left foot braking through long, fast corners feels as natural as walking, you have a hard time accepting dual clutch autos as the "better" alternative because with the driving experience faster =/= better.
if you drive a manual car fast and don’t rev match downshift, you make the rear end unpredictable and can even lock the rear wheels in certain cars. it’s about matching the engine speed to the wheel speed and that is of paramount importance, unlike double clutch upshifts which are a bit of a relic from the non synchromeshed past..
Imagine ranting over another persons enjoyment of perfectly rev matching a nice manual gearbox in a sports car on a great road. A skill they’ve worked on since being 17 years old reading Evo magazine. What a 🤡
MR folks need to take the GT4RS and swap a manual with short gearing. maybe then Porsche may offer it as a factory option.
And that my friends is how to review a car 👌🏻
I’m predominantly road oriented, so the gearbox upgrades are the only ones that really appeal to me here.
I agree , the other bolt on parts seem a bit underwhelming
I really like the wing
IMHO the way to go is this: Boxster GTS 4.0 PDK, Surface Transforms brakes, Ohlins Road & Track suspension, Kline Inconel exhaust
Catchpoole you are a thespian of motoring journalism.
It’s that EVO magazine bloodline in his roots.
This comment has “use the word of the day in a sentence” vibes to it lol
Speaking of thespians, he has a look of Stephen Merchant in this video.
Absolutely adore the regular GT4, which you can still buy a manual with! And yes, the final drive upgrade is something this car is screaming out for!
Put the numbers to one side for a moment. 911's have become too large imo. Put a 992 next to a 997 and it really shows how bulky and oversized 911's have become. Yes you get more grip/traction due to larger wider wheels, but our roads have not become any wider nor have our parking spaces. Also the 992's are a lot heavier than previous 911's. So for me, since the 992's first came out, it's now the Boxsters and Caymans that are more appealing, as firstly I think they look better than the 992's, but also are more driver orientated and more 'sporty'
The options that Porsche offer for the Cayman/Boxster are really impressive imo. Can't afford a GT4 or a Boxster Spyder? No worries, get yourself a 4.0L Cayman GTS or a Boxster T. Even the die hard 911 enthusiasts must be a little more drawn to the Cayman/Boxster cars now than they used to be?
Spot on. Good on Porsche for finally deciding to stop nerfing the Boxter/Cayman (had a base Boxter for a couple of years before trading in on a Z06 Vette) so that we can finally experience that platforms potential. And the bang for the buck, as well as options available? Tremendous
Hell I thought the 997 generation was far too big
A real drivers car not for posers 👍.
Great writing Henry whether here or at Evo
If I ever get my 997.2 C2S I'm taking it straight to RPM Technik to fettle it
The Gear ratios in Porsches have always been to high. Second gear at 80+mph is just ridiculous and a 100+ in third is faintly to high. I've driven 996GT3 and found it crazy that an N/A car needed be driven constantly in second gear down a Country Lane.
I know it's an expensive upgrade, for a ratio change but it's probably the best modification. It'll certainly feel faster throughout the rev range and more involving with more gear changes and heel and toe and a bigger rush to the redline. RPM need to do this to the rest of Porsches models.
Porsche gearing IS unreasonably tall. I cannot for the life of me figure out the logic behind this consistent application either. Fuel mileage/emissions maybe? Drivability aimed to please the non-enthusiast that so commonly buys these cars? Leaving extra performance room for upgrades (to GT 2/3/4, RS, turbo models etc., or even aftermarket like this example)? Some combination of these, possibly combined with other factors? Who knows.
I will say that a few years back when I traded a Porsche for a Z51 Corvette (both were 6-speeds), the gearing on the Corvette was *even taller*! Not by a super wide margin, but certainly noticeable.
That said, although shorter gearing would have benefited either tremendously, the Corvette was able to adapt to and overcome this unreasonably lazy gearing due mainly to its monster low-end torque and ultra flat power band.
The vette was objectively far better suited, even with its substantially lower redline.
It is worth mentioning that both the ease and cost of switching out rear end gear sets is far lower for Corvette owners. The varying options available to the aftermarket consumer are far greater as well. This price and availability discrepency is to be expected; Corvette vs Porsche aftrmarket tax (as silly high as the vette tax is as compared to, say, literally identical parts for Camaros (ex: $300-400 vs $1,050-1350 for exact same Borla exhaust/X-pipe. Only differences being minor such as bracket/mounting locations)
(I later had a Z06 that shortened this up a tad, but I still considered it to be far too tall. From 3.42 to 3.73 iirc. Ended up expiramenting with, aside from aforementioned 3.42 and 3.73 (along with some limited city driving in auto Corvettes with both the ultra tall standard, as well as "performance" 3.13 ratios): 3.90, 4.10, 4.11, and even a 4.56 which was my favorite.
The 4.56, as short as it sounds, felt ideal to me. The T-56 and TR-6060 6-speed manuals used in C5/C6 Corvettes and Camaros had very tall gears in and of itself; 3 of those 6 gears were overdrive! (4th is a perfect 1:1, with 6th being 0.5:1).
In my modded 02' Z06, I was able to not only maintain decent drivability (no annoyingly frequent shifts or low rev bucking), but ultimately hit an independently verified 212 mph (factory cars top out in 5th at recline, as 6th is far too tall to pull further. Factory C5 targas do 175; 6th on its own is only good for 130-140 or so. Increasing top speed beyond this requires either taller final drive to make 5th stretch further, or a shortening that is aggressive enough for 6th to actually continue pulling. Ideally you want to be at or near peak horsepower rpm when approaching drag limited top speed (obviously increasing your rev limit fuel shutoff will increase top speed when redline is the limiting factor. Power moss such as h/c/I and supporting additions such as a trunion kit, as well as professional tune, are highly recommended) I chose this, to 7,350, as well as the latter of the aforementioned options)
Still got 25, or even 30+ mpg on the highway when cruising. Also got rid of that pesky GM skip shift feature that forces a 1-4 shift under roughly 2,000 rpm.
(Eventually switched to a Ford 9" rear end due to GM's 8.8" being notoriously weak in high power applications. Just in case you were wondering about the discrepency w/ differentials)
If you think that is a bummer consider this: Most C and C Corvettes were sold with an automatic 4 speed paired with 2.73 final drive ratios! A buddy of mine had a C5 A4; 1st was good for like 70, and it reminded me so much of the old powerglides folks transplanted into heavy, yet powerful early 70's muscle cars.
Blame fuel economy/emissions regulations. You can fine tune an automatic gearbox to meet those regulations but not so with a manual gearbox since the driver does his own shifting. The only way Porsche can keep the manual gearbox around is to make the gear ratios tall to keep the revs down.
Shorter final drive sounds great, but the price is eye-watering. Four-five times more expensive than it would be for most other cars.
Great review Henry, what a car!
Excellent video! Gear ratios must be lowered, You chicken out because, with the second gear, you could be in jail.
When is the Emira back on your Agenda Henry?
Wish Porsche would just gove us these ratios in the GT4. Would be perfect. Dont need the rest done on this MR, just the gear ratios
Does this guy's heart rate ever get above 30? Lol
The most monotone auto journalist I've ever heard.
You look like you are bouncing and jiggling around in that thing... Aweful to drive on a road obviously.
I think the ticket is a 2,3,4 regear. 5th 6th are too good at the top. Pulls hard still
All unnecessary. GT4 is brilliant as is. Especially the 981. Spend the 40k on another car for the collection!
You could be right, but the gearbox upgrade might just make brilliant even better.
who is driving manual cars? that generation is almost de-ad
Only Doug can wear 2 tops like that like and get away with it
i think porcshce can do this "upgrade" easy, but business wise if they put it to the cayman then i think cayman will outsales 911
Correct
@Carfection you should try the DeMan 4.5L GT4 with the shorter gearing, its faster than a GT3. Farah loved it so much, he bought one.
Can’t get them in the UK / hard to get hold of I guess
Is it another engine or a stroked original?
@@idokwatcher2062 stroked original, either the 981 3.8 or 718 4.0, makes 560hp. Bore goes from 102mm to 108mm, Mahle racing pistons, Carrillo connecting rods, and a crankshaft from the 991-generation 911's flat-six are added to increase stroke.
This means that with the 4.5L its got 560hp, 438lbft (at least 100lbft more that stock) and with new gearing goes to 75mph in 2nd and 103mph in 3rd.
No, It's not faster than a GT3. I have the 4.5L with the short gears. It's a brilliant car and as fast as a GT3, but I do tire of the hyperbole around DeMan.
Fantastic review, honest and encompassing all salient points.
Another video by a Porsche salesman. No mention of the bad only the goods, no objectivity, no honesty. Its all about selling the car.
What are the bad bits?
I like a long 6th, as long as the engine is not struggling and I would guess that engine doesn't struggle at 1800rpm and 60mph.
Do they offer those gearbox upgrades for gts 4.0 too?
Yes, they do
This video isn't ratio'd by me, nor you. It's ratio'd by the stock manual gearbox of the GT4.
The perfect car for me would be a GT4 "Touring" with the replacement gear box, more road focussed suspension and lose the rear wing.
Sounds like the perfect car for you would be the Cayman 4.0 GTS

What camera setup do you use ?
I have modified my 981GT4 with all of these enhancements and do a lot of track days. Mine has 435bhp which also helps bring it closer to the RS which Porsche would not sell to me. The major advantage of the Surface Transform discs over PCCB's (Standard on my car) is the longevity of Pagid RSC1 pads. Three trackdays with PCCB's and ten trackdays with the ST's. I have now resurfaced my ST's for the first time ... they needed it after 50 trackdays. I would have gone through approximately five sets of steels in that time and the PCCB's ? All I can say is that on my previous Cayman R the PCCB's lasted 30,000 miles ... yuugh.
No they aren’t valid questions. It’s just a 718 that costs extra because Porsche couldn’t be bothered to put in a decent manual
Great Edit. But you cannot buy it only for existing clients and flippers !!!
6500 for a ring and pinion gear? GTFOH. Total rip off. Porsche should gear all manual cars to top out at 65 mph in second gear, that's a proper driver's car.
May I suggest something? Instead just sitting inside and driving the car, go thru the cars parts and location and explain the car.
Excellent film Henry and team!
