hi

i was just woundering if any one knows the differance betwwen the s4 turbo clutch and the s5 turbo clutch, from what i can tell, is that oem microfich and aftermarket part number's are differant, but both have the same spec's 8 7/8-22 spline (or 23 spline depends who info u are using) and 15/16 hub !and i am also using a s4 turbo clutch in my 86 na car with a 89 t2 trans, and it seams to work fine but the part number thing and not knowing is driving me nutts!!!the only differance i can see is the 70.00 price jump on the s5 stuff!!

I think the s5 is 240mm, and the s4 is 233mm.

I think the s5 is 240mm, and the s4 is 233mm.
