Got to love the wind on the roller doors thanks Jack for the info always interesting 👌
Hahah yeah bloody windy, thought the shed was going for a ride there at one stage! Cheers!!
love it ..the old stringline and ruler... no laser bullshit needed here!
That's it!!! Cheers!!
Great idea with the plastic paper sleeves mate! Genius
I can't claim this as my idea!! But yes much easier, and cheaper, than greasing up aluminium plates!!
Awesome vid as usual jack. I really miss that era of racing
Thanks! Was a great time for Aussie Motorsport!
Very simple but effective way of wheel aligning Jack, I used to do my own "string line" alignment procedure on my old double live axle four wheel drive, it always worked out fine. Sometimes the basics are the way to go, if you know what you're trying to achieve.
Yep, providing the strings are parallel it's hard to really stuff it up! Cheers!!
Love the old school alignment method. I've used the good ol string method myself on road cars. You've added the element of stiction which I had no idea about. Very informative! Very keen to see the camber\castor adjustment and ways to measure ir in a similar simple way. I know it's a bit harder and I've never been able to get it reasonably close at home.
Yes you need to make sure the tyre doesn't stick to the ground and not give you all the information. Also make sure tyre pressures are all set to an even value, and i also rotate the wheels over the setup incase they have been in a crash and where you are holding the ruler for toe measurements is bent or something. Current day teams would have set up wheels where that surface area has been machined true.
Always interesting, Jack. Thank you 👍
Glad you think so! Cheers!!
Wow Jack,that is one good looking beast of Car, Larry had the best looking colour combo, in my opinion. Cheers Steve.
Yes they are iconic looking cars! Cheers!!!
Thanks, Jack ... I watch with interest as you show and describe actions I'll never get to use. Keep them coming and I'll continue to enjoy them. 👌
Cheers!!
Thanks Jack, interesting as always 👍🏻🇦🇺
No problem 👍
This video was so cool to watch a race car set up stuff
Cheers!!
So 4mm toe out, total, more than I expected, to be honest. Very interesting video, looking forward to the rest of them, good stuff
@@timjohnun4297 yeah that’s maximum. I’d need to double check where the settings ended up on the 1993 car, was probably closer to 1mm out per side for Bathurst.
Love the content jack, just ordered some more merch
Awesome, thanks for the support, much appreciated!!!! Cheers!!
Looks a bit tricky to setup! Sounds windy and rainy there ⛈
Thought the shed was going to blow over! Cheers!!
Super 2 winner in a mighty Blue Oval FORD.
@@J_S209 you got it! Think that was my 3rd Super2 win in a Ford!
I know remote control cars are toys (but run on the same principles) but I used to always like a bit of toe out, it helped to get them to turn in and worked better on low speed corners kind of like Ackermann
Yes still similar as you say. Toe out in the front definitely helps the front in corners but it can scrub the tyres also, creating higher temperatures and more wear.
Good stuff, enjoyed that for sure, Cheers man.
Glad you enjoyed it, Cheers!!
Fantastic, once again. Thankyou :)
You're welcome, Cheers!!
Cool thanks mate
Cheers!!
Thanks for the info! Would love to know how much caster these macpherson strut cars would run!
@@georgepieratos5056 typically as much as you can handle without power steering! So these cars from 1993-1994 were 2.5-4degrees max. Then the steering weight was just too heavy. With power steering you could crank much more on. Cheers!
Love the fact its still much the same as it was except for the car mounted string line bars. I assume this method could be applied to any solid axle car?
Well I guess so, but you need to make sure the diff is in the right spot or else you could end up falsely setting the toes if that makes sense.
@@perkinsengineering yeah, that does make sense. Knowing my luck I'll mess it up haha
This is a very interesting video Jack. Do many of the teams nowadays have proper wheel alignment machines or is it mainly old school like this? Also what is the ute that you have hiding under the cover?
@@tomnewham1269 no one in supercars uses a wheel alignment machine that you would find in a Tyre shop for road cars. They just aren’t accurate enough.
cool mate
Cheers!!
do you think full steam it would be faster today with what we know in 2024? no mechanical differences, just knowledge?
This is an interesting question and it's harder to answer than you think. The two main reasons are, 1) the tyres are vastly different now to what they were back then, in terms of construction, compounds, sizes etc., and 2) the circuits are different with surfaces and what not, so actually finding a way to compare the two times is hard to start with.
Just knowledge, then possibly but the knowledge today comes from technology and hardware.
Hope this kind of answers the question!
My Father taught me a similar way!
How good! Cheers!!
@@perkinsengineering He was a massive fan of your Father!
Perhaps I did not listen too well or I am ignorant, but it seems that the front had toe-in not toe-out, as I think all rear wheel drive cars are set up to have front-toe-in.
@@brunoterlingen2203 front definitely toe out 👍👍
Hey jack, any chance of some Perkins engineering flags/shed banners anytime at all?
Maybe, we had a few people ask for polo shirts, so we did them and there's quite a few still on the shelf here! So once we move a few more of those on we can look at some new gear for sure!!
Jack can you please 🙏 get Larry on cam about the 3 legged to four legged factor!? Which supplies more support?!!…
3 leg's takes out any issues or factors that could arise with the 4th leg! Support is arguably the same but the search is for accuracy on the base not so much support if that makes sense. Cheers!!
all great Jack, no golf or whatever it was you said, oh polo shirts nah , not here! no sponsors.
Polo shirts look great on the golf course! Thanks for watching!
@@perkinsengineeringgolf is not my thing Jack , is what I thought I made clear, no matter. its friday night in the shed👍👍👍
Just seen on some old footage a vl in some castrol colours where is this
@@lukeroberts2164 was in our workshop recently, it’s the Bob Jane T-Marts one. Same car
soooo....does each race track dictate different wheel alignments,or once you have done this your done n dusted for the season apart from the obvious bumps n grinds during race season.
Oh there's lot's of variables, shorter tracks/circuits with more corners may mean you can more toe out on the front as it can help the turning, but then on a longer track more toe out or in can slow you down on the straights. There's also arguments for more front toe out in colder conditions to create more tyre temp or even in wet conditions. Most cars and teams would have a 2mm out at the front, 2mm in at the rear starting point or baseline and kind of go from there. Zero rear toe can help straight line speed as an example.
Does Larry still build 308's for anyone?
No we haven't done customer engines for a very long time now!
PRIMO!
Best i bring my VY Commie needs a front wheel alignment, chews the edge of tyres up front, thanks!
Cheers!!
Hahah yeah check the toe's and maybe camber!
mic audio needs fixing and tomany sponsor plugs, adds a shit
Can you buy me some audio gear and pay me to do the videos then?
@@perkinsengineering ... great response, Jack. Don't worry about the nay sayers
Who cares, you can hear it! We watch for the raw content here!
Cheques in the mail Jacko.
Nobody is making you watch this free content Brad.
You know when your wheel alignment bloke looks at your wheels by eye and then adjusts the front wheels on the wheel alignment machine and then checks it and its spot on based on the OEM and your driving style of your car, thats how my wheel alignment was done when i first got my VT Berlina 5lt done when i changed the rims to VS senator 17" HSV rims, from the stock 16" berlina wheels. ✌✌👍👍🦘🦘
Haha good stuff! Cheers!!
@@perkinsengineering no worries i hope your dad is doing good, last time i seen him was in 1998 after selling aircraft grade stainless steel welding wire with russell ingall etc. Stay safe and good luck go, Holden✌✌👍👍🦘🦘
