Default Dual Mass Flywheel Clutch

I'm considering replacing the clutch in my 90 ZR1(engine modified to 425+hp) - will keep DMF setup. Any aftermarket clutch recommendations? - Thanks, Vance

20 hp more than the stock 405 hp the 93-95 LT5s made isn't enough difference to warrant a clutch upgrade. In fact, Marc Haibeck has applied his 500+ package to his LT5, and prefers to use the stock DM flywheel and Veleo clutch setup with no problems. Even at 450 hp to the rear wheels (pushing 530 ish hp) the stock clutch clamps sufficiently.

Now, after a few launches on the drag strip, and any clutch will suffer severe lifetime expectancy reduction. If you intend to drag race - more than say a dozen passes a year, then perhaps going to a dual disc RAM setup might be in order.

My 91 has Marc's 510 package with the stock clutch and flywheel set up no issues.
