how much faster does a clutch wear when preloading?

 

Not a whole lot more. A better question is how long do your axles and tranny last if you don't.

 

yeah thanks i tired of breaking axles

 

organic clutch? (god i hope not)
if it is not, it really isnt that bad.

 

competition clutch stage 5

 

Thats the clutch I have been using.

Recently, when I changed my tranny I noticed that the PP and flywheel both had a lot of hot spots on them. I was not sure if it had come from preloading or just typical beating on it at the track. Apparently, they are from 2nd or 3rd gear burnouts and such!!! haha

 

The clutch deffinately wears faster but it all depends on how long you are preloading for. I made the mistake on preloading and revving it ready to launch too early the other guy staging was going slow. Got to the end of the track and then the awful smell hit lol I am on a stock clutch though. looking to upgrade but i really dont know what to get. The point is its cheaper to replace a clutch rather than axles breaking leaving you stranded or killing your transmission. And my transmission new is something like $3500? Thats how many clutches? lol

 

"hot spots" on the friction surfaces is very normal. Especially on all metallic discs

 

Another thing you may be able to help me with is material thickness of these clutches, although, you are for Spec clutches. When I was taking a look at it, there didnt appear to be much more than .027" if that of material left before the rivets that were holding the clutch material on.

I do not remember how the clutch originally looked brand new when I installed it. It still holds fine, but it appears to be wearing thin. Its not in a super high hp car and maybe has seen 20 passes down the track. Just curious about material thickness since we are on the topic of clutch wear.......
