so i'm rebuilding a s4 t2 diff. using a diff that has 200k miles on it. each clutch plate measured at 1.73mm..... . so i'm planning on using the mazdaspeed thicker clutch plates and thicker thrust washer.

i was wondering what the estimated preload would be with:
2.00mm brand new clutch with outside pins x1 each side
2.10mm brand new clutches with inside pins x2 each side
and the .2mm over thick thrust washer per side.
so that's .4mm over on each side.

0.8mm total in increased thickness.

looking for about 90-100 lbs of preload on the s4 t2 diff.

2nd question. what are mazdaspeed 2 way diff's or just any aftermarket diff's preloads?

3rd question. if i change the order of clutch plates, would i get an increased amount of preload? and how would i want to do this?

instead of having Thrust washer, 3 springs, clutch plate with inner, clutch plate with inner, clutch plate with outer.

should i do thrust washer, 3 springs, clutch plate with inner, clutch plate with outer, and clutch plate with inner?

4th question. if i was to shim my diff on top of using new plates, where do they go? i'm guessing on the side of the springs next to the end of the stack?

any and all help would be greatly appreciated and heard.
