Clutch for Cosworth SC
Posted: Fri Jun 12, 2015 8:33 pm
My (stock) clutch is slipping after about 5000 miles with a fairly-ordinary Cosworth installation (low-compression Cosworth pistons and a 3.1 pulley). Haven't dyno'd the car, but you get the idea. Need to order a new clutch ASAP, asking what the best combination would be. I don't feel the need for a lighter flywheel, don't race the car, but also don't want to be replacing the clutch again any time soon. Pedal pressure isn't a huge deal for me (I actually think the stock clutch is overly soft), but of course I don't want it to feel like a truck either.
I'm looking at the ACT heavy-duty and Xtreme pressure plates, presumably with a 6-puck sprung disk. Is the HD plate enough to dependably hold this car, or should I go for extra insurance with the Xtreme? Is there another combo I should be looking at? I hear GWR is coming out with a new Exedy combo -- should I wait? If so how long, and for how much benefit?
