By pining the front pulley to the shaft they've eliminated the de-coupled (random) slipper. the outer hub flat key drives the rear. Now its like a touring car with a slipper...

I really like the way the clutch basket works, its very predictable and allows for tuning front rear bias w/pad size. I run a Novak 4.5 14mm rotor, boosted 60 on a RX8, geared 14/58. It, with other tweeks and weight balance took almost 2 seconds of my lap times , just by being able to jump farther and get on the power earlier.

This track we run at is huge. my only problem now is i have to be carefull braking, it will flip me truck at the end of the 200 ft straight! Looks retarded watching your truck flip off the track
