I'm starting to get my rx7 back together and I have two clutch's sitting around to pick from.

I have the clutch from my car that I imagine is probably the stock clutch, and I also have my friends clutch from his car, his looks to be in better shape so I was gonna use his, but it is slightly different from the one that was in mine, anybody know anything about it?
my supposedly stock one is the top one and the one from my friends car is the blue bottom one. the springs in it are the difference.

 

The clutch discs are pretty similar. I think the first disc is a stocker.

I'd measure the thickness of the discs and run whichever is thicker. They both should be fine.

The blue pressure plate is definitely aftermarket. It might be Spec, I think their PP's are typically blue. Regardless, it's probably heavier than the stock pressure plate (as far as spring load).

Run the thicker disc, the blue pressure plate, and if they're in good shape and have good life left you'll have a setup that will hold a good amount of power and be super easy to drive.

thanks for the great response and advice, its much appreciated. I didn't think of swapping clutch disks between pressure plates. I'll measure them up.
