Ruined my clutch racing...

[j.fro]

I've had the Aasco LWFW and a sprung Spec stage 3 plus clutch in my autocross car for 5 years/40K+ miles and it works great. If you are going with the LWFW, be sure to get a sprung clutch, not the solid unit that would match the dual mass FW.
There is certainly a difference launching with the LWFW and a grabby clutch. It takes minimum 2k revs, fast feet, and nobody in front of you.
While the 986S is no wheelie-bars&parachutes drag car, it's not a turd off the line either.
