Question How long does stock Clutch last?

Tried doing a search but couldn't find much.

I'm curious how long a stock clutch will last with no mods/ all stock.

The second question is how long would a stock clutch last if say you are running around 300rwhp?

And finally, how much rwhp can the stock clutch hold?

I just heard of a guy this weekend with over 100k miles on his car that was still on his original stock clutch.....
Needless to say, mine doesn't last that long!

if you drive it properly a stock clutch will last the life of the car, or until the stationary gear o ring fails so about 70,000miles give or take.

with 300+rwhp it wont last very long, under 10k miles?

the life of a clutch is 70% dependent on the driver

Depends a lot on the driver. I once asked a dealership what the realistic life is for a clutch. He told me a story of a wash boy who burned up a new cars clutch in one day. Tom

I have just recently added a downpipe to my otherwise stock (suspension mods) FD. I am currently at almost 95K miles. So, what y'all are saying is that I should start shopping for a new clutch pretty soon?

Yes. Mine lasted 50,000 miles, and had been babied in general for the first 30k miles (before I bought it). I drove the car hard, but didn't abuse the clutch (drag racing, riding the clutch, etc). The stocker never slipped, but was grabbing so high that I could barely reach the wheel b/c my seat was pushed so far back.

I bought an ACT street/strip clutch w/8.5 lb flywheel and (almost 2 years later) am *very* happy with my decision. Clutch still is going strong and the flywheel makes my 7 rev like a motorcycle in 1st and 2nd gear

thanks guys,

yeah, i would agree that 70% of a clutch depends on driver. Some people can burn a clutch up in a day..maybe less! and some cars can last over 150K with stock clutch...one of my cars did.

So in general, a stock car with a stock clutch driven correctly will last over 50K miles

but once the car is modded, will probally only see another 10K of use.

I just replaced my stock clutch it had 143K and was original. It never slipped until I modded the car, now with my mods when I went over 10 PSI it would slip. So I replaced it. My car was highway driven alot.

Original owner '89TII-145,000 miles. The reason I replaced it was if I "hit" 2nd gear hard it would slip ever so slightly...No other time. When I pulled it, it had a lot of lining left, it was the pressure plate that was weakened from the heat.

Stock clutch doesn't like hard launches

Mine feels like it's slipping in 1st
25k on 2nd stock clutch. Time to start collecting soda cans to save up for a HKS twin clutch!

None. I love it. The 7 revs much faster in the lower gears, and driveability isn't compromised. Every single fd-owning friend with a stock flywheel loved the way my R1 felt. I have the flywheel that SR sells, btw.

I've got the OS Giken twin...HKS is just as good though.

You will absolutely LOVE it. It's so streetable. Engages so smoothly, let holds power like the clutchmaster stage 5...

still stock clutch

85K on the original clutch. Plenty of city driving. I started mods at around 45k miles. At this point I would not mind if it went cause the lighter flywheel seems like it would be nice.

mine lasted about 75k or so....
as everyone else says, "it depends a lot on the driver" where and how you drive, and what power you are putting down

I shift all the time; double clutching and all too. And I love to downshift from 5th to 3rd against American Muscle.

First one went at 42K. Second one replaced at 68K but not due to wear as my transmission went bad. The first two were OEMs. Through the first 75K, 10-11 psi.

The third, installed by PFS, was a CFDF and the car is at 93K now.
