Will this fit my S-chassis?
Yes, if you have a 4 stud rear, then you will need to re-drill the rotors to suit and use 2pot calipers. If you have a 5 stud rear, then it is a straight fit, but you also need to ensure you are using 2pot calipers.This kit will only work with those calipers and not Brembos.

NOTE: #2:Will not work with aftermarket knuckles.
NOTE: #3: When used on Z32 300zx or R34 alloy knuckles a .3mm shim is required to space the caliper correctly (included)
NOTE: #4:It is recommended to use these in conjunction with braided brake lines.
