Hi guys i have an Civic Ek, whit a b-series Crower stroker motor. I am using it for drag racing and a bit of street driving. I have just killed my Exedy stage2 3pad, and a Act Ekstrem clutch clutch. And i have to buy a new clutch? But which clutch should i buy?
I am pretty hard on my clutch at the drag strip, and using 23drag slicks.
I Am thinking about the RPC STAGE 4 CLUTCH? Or maybe a clutch master of some kind?
What would you guys choose?

 

I recommend the Competition state 4 sprung clutch kit and either of their flywheels. I've driven on a few different clutch setups and this one is my favorite. The pedal feel is almost identical to my old Exedy stage 1 but the CC4 obviously has a more aggressive bite. Once its broken in you can drive this clutch pretty smoothly. I only have ~700 miles on mine so far so I can't speak to clutch life yet but since ~30 miles I've been beating the hell out of it. Street tuning + 30-40 1/4 mile passes already (including burnouts and 2 step launches) + 15 dyno passes.

With any upgraded clutch you should upgrade your mounts too to prevent the motor from moving too much on engagement. I'm using all stock mounts and filling the 2 lower torque mounts with window weld was enough to keep this clutch engagement smooth. Poly mounts all around will soften the engagement up even more but I cant stand the vibrations of poly mounts.

 

Firmer mounts will definatly help on a launch. A Stage 4 clutch is going to be extremely hard to drive on the street just FYI, I'd only consider it for a drag-only car.
