Tried searching but this seems to be an elusive piece of data. I recently purchased a used set of stoptech st-40s supposedly off a B5 S4 from a forum member - I knew they needed to be rebuilt so no worries but after disassembling them I measured the pistons and got 34/40mm respectively - As I was sourcing new dust boots/seals I was informed that the piston sizing is incorrect for the B5 S4 application and not what Stoptech specifies.
Would anyone be able to share the piston sizes of their stoptech st-40 calipers or have a spec sheet? Thanks in advance!
