Doing a trans swap and am trying to figure out if I have a 215mm or 225mm clutch. Engine was from an '82 track car but I'm not just assuming it's a 215mm. Is there a way to tell based on the pressure plate or do I have to pull it off and measure? I don't need to change the clutch at this point but I'd like to know for future reference.

Here's a photo...

 

215mm pressure plate. The disc can sometimes be a 225mm but you will have an unused lip of 5mm around the outside edge. No lip = 215mm disc.

 

Thanks, glad I know now. Any experience with a heavier duty streetable 215mm clutch and pressure plate? I know it's harder to find than the 225mm.

 

They only come in a race version. I found it hard on the left leg for daily use in an '83 or older car. The 84-85 is different (easier) because it has a helper spring.

 

What transmission are you swapping to? Just making sure the same setup will work is all - good luck!

 

Trans is already in. I swapped to an SE transmission. I will most likely end up with a Centerforce Stage II or Dual Friction setup, they make one for the 215mm and I want streetability. I do get a bit of slip out that large streetport once in a while but the clutch is basically new. It's just that the stock disc isn't grabbing as much as I'd like and I wanted to be sure what I had before I ordered one.
