ACT street disc, heavy duty or extreme pressure plate?

[turtl631]

I just found out that you can get ACT street kits with either the heavy duty or extreme pressure plate and the organic disc. I'm stock now but I want to turbo my KA relatively soon to around 275-300 whp, whihc would be a better option? This is a daily driver mostly, some mountain roads and autocross too. Thanks!

If you treat your clutch kindly the HD plate could very well be enough for you and will keep the pedal effort closer to stock. The Extreme is just a higher clamping force and so will have a higher pedal effort. If you are ok with the additional wear the Extreme will cause, I think it would work well with the street disc.

Hm, now comes a tricky decision. What do you mean by additional wear? The friction disc will wear out quicker? If so, I'll stick with the HD, which is a little cheaper anyways. Thanks for the reply!

No, disc wear will be far more dependent on how you drive. If you are a clutch dragger, then you'll heat and wear it fast. If you are a gorilla clutch-dumper, you will increase the shock loading.

As to wear, with increased pedal pressure comes increased wear at the bushings and shafts that the system travels on. These include the bushings and shaft at the top of the pedal, the master cylinder pushrod, and the clutch fork at the supporting pivot. Also, those flimsy stock pivots are rumored to break under "performace" clutch systems. Whether this is true or not, you can get this little nugget as cheap insurance.http://www.courtesyparts.com/M...CLTPV

already ordered an SPL clutch fork pivot, hehe. However, I think I'll stick with the heavy duty pressure plate. No sense putting undue stress on the system, and its a little cheaper. PLus i have to daily drive this thing in chicago and atlanta traffic
