I have a Stage 2 Competition Clutch I bought from a friend of mine. He used it on a 285whp boosted b16 for about 15k miles. The disk has veryyyyy little meat left on it. I was thinking of just ordering a new Stage 4 sprung disk and keeping the pressure plate. I read that all the pressure plates are the same from stage 1-5, only the disk are different.

So my question is would it be fine if I just bought a brand new competition stage 4 disk and used the same old pressure plate?

 

As long as the pressure plate is fine and within spec, there isn't a problem in doing this. Resurfacing for proper break-in never hurts either...

 

If you want to post up some pictures of the surface of the pressure plate, I'll let you know what I would recommend.

Be aware, that if the clutch was slipping a bunch the diaphragm on the plate may have lost some strength, but yes the pressure plate is the same 2 vs 4

 

The clutch didn't slip to my knowledge, his motor ended up cracking all 4 pistons and he decided to fully build it and get a clutch to support 400whp+. Which is how I ended up with the stage 2 for a great price .

Anyway here are the pics;

 

That thing is TRASHED... get a new whole new clutch assembly.

 

If you can measure the thickness on the disc and check to see if the pressure plate friction surface is still flat, it could be usable on a stock car.
