Quick Overview of Karcepts Rear Wheel Hubs | Honda S2000

- In the last few videos I covered how to replace the rear wheel hub and bearing on a Honda S2000. The reason I bothered to change my rear wheel hubs is because I upgraded to Karcepts rear wheel hubs! This quick video explains why I did and a little overview of the hubs themselves.
Note: Tony walked away from his rollover at Buttonwillow without incident thanks to his safety gear!
Thanks to Matt at SpeedFreaksUSA as always for sourcing the Karcepts Rear Wheel Hubs for me.

Yes I'm OK. Only thing salvageable from the car was the drivetrain. Unfortunate but the MR-S has zero options for stronger hubs, luckily S2k does. :)
Glad you’re okay. That looked pretty harsh.
I’ve never seen an s2k flip! Thankfully you’re okay! Did you have a roll bar or was it the oem roll hoops?
@@kassiypomme7696 I don’t think that was an s2k
@@suryamp12 that definately wasn't an S2K
It was an MR2, but it did break a rear hub in the same way an s2000 could. It had a roll bar.
"further strengthens the metal IDK" made me laugh out loud
Been running these for about 6-7 events now, no issues :) Great product imo.
I had my set installed last week and it got rid of a vibration I had whenever I was driving between 68-75 mph.
woahh dude that crash was a pain to see, makes me realize how lucky i have been when i go around a corkscrew at my local racetrack.. great upload man, i will consider these
nice video, i plan to do these over the winter
Agreed, 100% worth the peace of mind. When doing the rear wheel bearings, might as well do these at the same time and not worry about it anymore. Fit with OEM axles was perfect as well.
Thanks, will check these out! I've read a while back amongst a lot of s2ki digging the rear hubs tend to last 2-4 track days with stock no air flow rears (no air ducting/bigger rotors for dissipation etc.) and even with decreasing the temps at the rear they won't last much longer.
I think they last plenty long. I’ve done about 40 track events on OEM or eBay hubs
Wish i knew about these hubs, i just got oem hub and bearing done
those POVs were scary
Oil quenching hardens the steel and tempering makes it less brittle.
Wow. I didnt know. Thank you for sharing that information.
Greetings from Germany
Man I'm really glad I saw this! I thrash the living daylights out of mine so I'll probably do this upgrade once the parts funally arrive to adapt to the Ford Super Coupe rear end I purchased a while back.
Thanks for the videos, overall. If you ever find yourself at a Gridlife event and see GLTC car #168, there's a beer for you.
Can you follow up with a review on this hub after a year of use? I’m thinking about upgrading too for peace of mind
I don’t know how much I can review these beyond they broke or they didn’t. 😛
Do they come with those sealed bearings as well I saw you used in the installation
Do you know the specific failure of the the OEM rear hubs? From the video clips, it sounds like the hub itself cracked and failed catastrophically. The thicker design and improved material (chromoly >> cast iron) of the Karcepts will definitely help!
I should only worry about when the car is being tracked?
Yes. Heavily on very sticky tires.
The OE wheel hubs should be fine though on a casually driven occasionally driven street car only?
Yep
Are these hub failures like something can happen outta the blue despite age/mileage of the S ? Or just after a high mileage/lots of track days S2k ? My ap1 has 68k miles and around 11 track days. All though idk the symptoms of a hub about to go out, I have been hearing ticking from my rear wheels on hard cornering and take off from first, thought it was loose lug nuts but my lugs have always been torqued, now seeing this is having me question the fact if it’s my hub lol
if I planned on changing my hubs just bc would u recommend these for preventative maintenance in the future? I like being a bit over kill on everything to be safe 🤷♂️🤙
No
w/ the URGE Rr floating rotors, wouldn't the temperature expelled give the OE Rr hub a better sense of structural rigidity since temperatures were drastically reduced?
I don’t know about structural rigidity but I’d say the hubs would take less heat and last longer for sure.
Gary Wong who broke his rear hub was running the urge rears for probably over 50 track days though. Not sure how long he was on those hubs for though.
The rear hubs were about 2yrs old with about 50-60 day on them. Karcepts on now. 8 days so far. No issues 🤞
Heat is only one factor, but not the one that would mainly cause hub failure.
The tire technology has advanced a ton since the OEM rear hubs were designed. These cars are taking much higher lateral forces that are putting unexpected stress on OE hubs.
Karcepts hubs are designed to take more stress.
Is this upgrade more for track or would it hurt for people who drive more aggressive at times?
I dont think street driving will ever experience a rear hub failure like track abuse will.
Agree. Would not bother for street driving.
Ive brought a track s2000 but im daily driving it pretty hard, would you say past track abuse might of weakened them?
@@DIYGuysvideo thanks for replying. Seeing crashes like that just makes my heart drop and paranoid lol
at 1:52, you sounded a bit hesitant when you mentioned the hubs are oil quenched and tempered. Is that something that you feel is unnecessary? or do you not understand the quenching and tempering process when improving the hardness and ductility of a metal?
I just personally don’t understand the quenching and tempering process. The other points are pretty straightforward and understandable to someone like me.
@@DIYGuysvideo ah I see. its basically just that process of improving the hardness and ductility of the metal.
Briefly explaining, you heat the metal at very high temperatures and then oil quench (cooling it down) quickly so the grain structure changes to improve on its hardness. The downside is, even though the metal becomes harder, it does become more brittle. And thats where tempering comes in afterwards. You heat the metal again but at a medium to high temperature and you let it slowly air cool afterwards. That process releases the stresses and brings back some of the ductility in sacrifice for some hardness.
Martensite :)
@@DIYGuysvideo its the final step in history channels forged in fire - its the part that makes or breaks any blade
this is scary
That is the worst crash I've ever seen in an S2K.
That wasn't an S. It was a different car, used to illustrate the potential chaos a broken hub can bring. Highlight seriousness of the topic.
