Size Differences With Gtr Brakes

[spizr1]

Car 180sx -

dilemma - current r33 gtr NON brembo front calipers come very close to the spokes of my rims. Im upgrading again to r34 gtr Brembo breaks, just wondering if anyone knows the size difference and if they will fit. Currently have about 1cm/1finger or less space between spoke and caliper.

thanks

its a bit hard to be certain....the best way is to trial fit your wheel onto a car with those brakes. but 1cm is miles of clearance, its not getting close until you are down to 2-3mm.

If you are having issues with spokes clearing the calipers it is easily solved with a small (eg 5mm) slip on wheel spacer to space the wheel out.

The std gtr calipers are actually pretty wide and I think you'll find the brembos aren't much wider, if at all. I went from 32 gtr calipers to g4 8 piston ones on my stagea and there was more clearance with the 8 piston ones

BTW there were no non-brembo 33 gtrs. 32 gtr and 33 gtst are almost identical though.

yes I hope you didn't pay a premium for those R33 GTR non-brembo calipers as there is no such thing. all 33 GTRs had brembos, and they are the same as the R34 brembos too, both in caliper and in disk size. R32 GTRs did have non-brembo calipers and the 32 GTR v-specs have brembos which again are the same as the 33 GTR and 34 GTR brembos.

you most likely have 33 GTST calipers and rotors. don't forget if you currently have the calipers with the 296mm rotors when you go to the brembos you will be running 324mm rotors so the caliper will be spaced further out too.
