I burnt my SoftLok clutch out when it was almost new by not having enough base it and finding that out in eliminations.
Since then i've erred on the side of too much base and i've got no idea how much is in it now but it works fine. No counterweight at all.
The thing with 9" tires on a front-heavy car is needing to be able to launch as the track allows. If the cars ahead of me spin bad i'm not tied down to a 6000rpm leave to make the clutch work. It's going to work at 4000 if I need.
How quickly you jump off the pedal and what throttle position you launch at matters too.
