Ive been out of the game for a while so be easy on me. Im having Shepstrans rebuild my Evo 9 tranny right now and I'm going replace the clutch. The car is going to be set up with basic bolt ons and tune, not going for big numbers just want a good daily.

my question is what clutch do you guys like for that set up? any tips would be great..

 

My car is setup with basic bolts-ons making 339 whp and 390 wtq on a Mustang Dyno. I just got out of an Exedy stage 1 clutch that locked me out in high RPMs which was very frustrating. I went with an ACT XTSS even though there are some threads on here with people saying this clutch locked them out. Mine has been smooth as butter at high RPM's, it's like having a new car after the last few years of putting up with that Exedy. I couldn't be happier.

Also the pedal feel is much closer to stock than the Exedy as far as release point and stiffness IMO.

 

I would say Exedy twin just in case you want more power down the road. Or the Comp stage 2

 

Comp stg 2

 

thanks for the help guys

whats the good websits with best deals to order this stuff now ?

 

This^

I enjoy driving my car with the comp stage 2 on OEM flywheel.

 

Exedy Organic HD with matching flywheel.

 

+1 for Exedy Stage 1 organic (05803HD)

CBRD recommended this clutch, and I've been using it for a few years now on my daily driver (basic bolt ons and a tune, stock flywheel). It's slightly heavier than stock, but I got used to it pretty quickly. Highly recommended for this application.

 

Is Exedy still making the SD twin? That was a great compromise between drivability and the ability to hold higher levels of power.

 

XTSS, inexpensive, holds like a bear trap and LASTS (Do you know how much it costs to swap a clutch!!!) My Evo IX MR had one put in at 46,000 miles and currently has 124,000 on it and it still holds perfectly fine.

^^ thats impressive
i just have bolt ons as well and its 100% daily everywhere car.
comp st2 is nice but started slipping after 24k ish miles from daily traffic
im on comp st3 now, pedal is oddly soft, very easy to drive, will see how long it lasts in daily traffic.

 

I think it's possible that for many of the times that people report having a clutch lock out on them, it could be due to the fact that the higher clamping force will only accent any problem these cars already have with drivetrain movement causing lockout. So if you go from a worn clutch that was slipping, to a new clutch with a stronger clamping force, it may just be time to get some motor mounts.

 

Adjust the clutch for proper use. If you are extremely scared of lockout get a Sprung 6 puck which is far less likely to lock out. A six puck will hold a LOT of power. I believe an un-sprung unit would hold well over 700WHP. Keep it simple. The twin discs are nice and fancy however thy do not last and cost so god dang much plus the labor to replace it. I mean the Exedy SD slips over 400HP, what is the point when an off the shelf XTSS would hold about 550WHP and LASTS!!! Is it smooth as the Exedy? Nope, but how much is smooth worth to you?

 

Can't really go wrong between the ACT XTSS (could even get the hdss for a lighter pedal), a Comp STG 2, and the Exedy STG 1 organic..

 

I would skid the HDSS altogether, it isn't that heavy. At least to me however I have been driving a 4G63 of some sort with a heavy pressure plate since the 90's. XTSS all the way. HDSS leaves no room to grow, XTSS can handle some serious power and torque. Either one is a superior choice to a SD Exedy twin.
