Rim size for GTST calipers

[Richelieu]

Will the 4 piston calipers off an R32 or R33 GTST fit under 15" wheels? Its for a rally car.

It would depend on the offset of the rim and the total internal diameter of the rim.

I'd say you have a better chance of fitting 32 brakes as they have a slightly smaller disk and as such I assume the calipers don't extend as far from the hub and also the calipers are smaller overall.

FYI. I've just fitted larger disks and calipers off what i think in an R32 GTR Vspec 1 under my stock 16 inch rims. It required some clearancing of the caliper to fit but the disk is 25mm larger diameter with a larger sumitomo caliper (same pad size though) so I reckon you could do it.

Pretty certain they will. I know someone who sprints a 260Z, and I'm pretty sure he only runs 15s, but has 300ZX calipers (same as R32).
