Hey, I'm looking to buy a SPEC stg 3 from a friend of mine for a T-45 application, but when I took a look at it I still had a few questions about it I couldn't answer and neither could he.

Firstly, I always thought the Stage 3's were six puck designs while this disc is a 4 puck design.
Next, the pressure plate looks different than the one that came with my KC clutch. It has a round disc around the edge like you would see on a brake rotor if that makes sense.

Everything else looks good however and the Part Number on the clutch is SF483.

 

Go to specs web site and check it out. Is there a part # on the clutch?

 

EDIT - found specs website and the p/n checks out, but still doesn't explain the 4 puck clutch disc. I guess it's just an older design or something. I'll just put it in and find out.

I already did that and went to spec clutches. com and it directed me to latemodelrestoration so no help on that. The SF483 should be the model/part number, but I can't find anything on it. Clutch is still in box and wasshipped direct from Star Performance Engineered Clutches, so I don't think its not a SPEC, but maybe did spec use a 4 puck design before switching to a6 puck?

 

I think you can order 4 puck clutch disks. Check this out: http://www.machperformanceparts.com/mp/SF872-2.html
