RZ rotor caliper height
Does anyone know how much thicker the RZ rotor/caliper combo is compared to the stock combo? To be more specific, I need to know if Gram Light 57F-Pro's will fit with the RZ caliper/rotor combo. At the moment, I am planning to get 18x9 in front and 18x10 in the rear with +47 offsets all around. This is confirmed to fit with the stock calipers/rotors. Please help me out! Thanks.

On Volk's website, they state for the 57F-Pro that the A-disk is for the large RX-7 brakes (RS/RZ brakes). Therefore, it is likely that the B-disk will not clear the brakes. Unfortunately, many of the A-disk wheels have offsets that are too low to properly run on an FD.

On the A-disk, the spokes will bow out more and connect to the rim farther out (less lip) to provide more clearance for brakes. The B-disk has shallower spokes that connect further back on the rim, giving a deeper lip but less clearance for brakes.

No. If you are going larger in the back, you can run the B-disk for the rear, so you can run the 18x10 +4x offset there.

I recall Rishie fitting 9 x 18, 40-mm offset 57 F Pros all around with 255/35-18 tires on a customer car. Do a search, and you'll find it. Don't know what disk was. You may have to consider other wheels for the proper clearance.
Clearance issues is what makes choosing wheels so damned HARD!

If this is correct, what can I do to make these rims fit with my RS/RZ calipers/rotor combos? Run B-disks all around with spacers? Thanks for your help so far rynberg. I appreciate it greatly.

Volk Alternatives:
5-spoke: GTC: Face1: 18x9 +42 offset (A-disk), 18x10 +50 offset (B-disk), with 255/35 front, 285/30 rear
other: CE28N: 18x9.5, +47 offset, run 265/35 all around OR LE37T: 18x8.5/18x9.5 +40 offset, 245/35 front, 265/35 rear
Non-Volk Alternatives:
SSR Competition: 18x9.5, +50 offset, 265/35 all around
SSR GT-1: 18x9, +45 offset all around with 255/35

For grins and giggles, I mounted 9.5 x 17, 42-mm offset SSR Competitions with 275/40-17 Hoosier R3S03s up front. They did fit, with no rubbing, while I went up and down my driveway curb, full lock to the left, and right.
Based on that, I would say, 9.5 wides with 255 or 265 wide tires would work up front using offset 42 offset (assuming the proper front brake caliper clearance, and overall tire diameters of < or = 25.3 inches).
I'm still waiting on maxcooper to let me know if 265/40-17 with 40-mm offset, 9.5 wide Volk SE37Ks fit up front on his car
I want 9.5 wide SE37Ks all around with 255/40-17s, max!!
