hi all i recently purchased a pair of rda 909 rotors to replace my under size rotors last night i tried to fit them and the rotor does not line up with the caliper it seems like the caliper needs a 4mm spacer to bring it out enough to line up i measured the step from the rotor face to to where the wheel sits and on my original rotors it is 28mm and the new ones are 24mm my z is an '89 tt and the calipers fit 30mm rotors any suggestions?
You've bought the wrong rotors. You should've bought the pre 1990 rotors to fit 26mm calipers. You'll need post 1992 callipers that run the 30mm rotors.
That's not correct. The TT calipers are all to suit 30mm rotors. Only the S1 NA's had the 26mm rotors.
my guess is (as Chrispy pointed out about sizes) that the supplier has supplied 89 NA rotors, that being the only aussie release available, we all know how much parts shops love imports.
ok just reread my roady and the rhs is 25.2 lhs is 27 and i think its just dawned on me what has happened some previous owner has put na rotor and caliper on the right hand side but the caliper fits over the the 30mm disk but won't line up when bolted in crap crap crap i'm going to have to locate a rhs tt caliper
