Is the Stage 4+ the Stage 4 with a stronger pressure plate?

The reason I ask is I thought ZZP was including new disks for the 6 Speed Swaps because the splines were different from the F35s, meaning the pressure plates could be reused if you wanted to, but the disks wouldn't fit anymore. So they've got an equivalent disk now in the F40 spline flavor? If so, that'd be great, as I could keep the non-puck feel of my current disk.

 

i've been on the southbend stage 4 that zzp sells and a fidanza for 2 years now. you know how i drive, and i have no complaints. stu had the gmpp in before this and i loved that as well. would still be on it if it would have held the power i was making. but while the stage 4 and flywheel hold amazingly, the clutch pedal is not what you would expect a clutch that holds that much to feel like. you're welcome to take it for a drive at ced. but with your mounts and the coilovers we're gonna need someone with big ***** in the passenger seat.

 

something like this...

 

any long term reviews?
