Im still trying to decide just how far I want to take my car as far as performance upgrades. If I build it up a bit I will go for the Exedy twin disk, but Im thinking I may keep the engine upgrades to a minimum and focus more on the suspension. What clutch would you guys recommend for about 300whp on a daily driven street car. I have never run at a drag stip and more than likely never will, but I am very interested in trying out autocross and maybe even some roadracing.

 

ACT EVO 8 street clutch for under $500 shipped!

 

Does it matter that its rated for 497 ft/lbs? Seems like it may put more stress on the drivetrain than necessary considering the proposed power output.

 

i was thinking of the exede twin clutch for my evo even though i will never hit 350whp because i was figuring twin plate means stress on clutch is always divided by 2... and i heard the engagement is smoother because of it

 

Unless you want to push 500+ whp there is no need for the twin plate. Ive heard many good things about the ACT and the RRE clutches.

 

i mean u are right but yeah lets say my evo is running only 300whp... that means with the twin clutch, i could slip launch my evo for many years without it slipping

 

I drove a twin and it was like a light switch....on/off. I feel the ACT street clutch is much more stock like for only a 300+ HP daily driver. Anyone who has one want to comment?

 

They can take alot of punishment but Im not sure about many years of launches. Just depends on how hard you are on it. Just remember that the twin plate will be harsher on your drivetrain, so if you launch alot you most likely will kill your diff before your clutch. Even with 300 hp you can kill the clutch but it is likely you would kill something on your drivetrain first. I remember having a full race clutch on a 200hp na RX7. I launched hard one night and snapped the top of the driveshaft. You dont need a lot of hp to break things.

 

the more plates the clutch has the more surface area it has to grip w/ the twin plate does engage quite nicely. One thing to look @ when considering some of the single discs is how many pounds of pressure the diaphram spring is rated @ (this is different than the ft lbs rating) one thing you probably dont want is an extremely heavy pedal feel. Also to heavy of a spring and you can possibly cause premature thrust bearing wear. So besides the nice pedal feel & grip of the twin plate you get a new flywheel.
