God no, I've had enough problems with ACT clutches in several Evo's I've worked on to make me stay away for life
South Bend Clutch

There's several options but the extreme duty 6-puck is sprung and rated for 800+ ft/lb's of torque (in a skyline weight chassis) Since you have a multi-disc you'd need to find an RB flywheel. The pedal stiffness is not bad at all. I have driven ACT, RPS, etc that are way worse.
What trans are you running? I also did this upgrade and it made the pedal feel significantly better. This fork is much less prone to flex with higher clamp load pressure plates.....

It says' for 300ZX but it works just fine with my RB25 bell housing.
