First Scooby-Doo "Rhuh-Rhoh" Moment - Brakes Question

[Avalanche325]

I have the FFR Wilwoods and the FFR 17" Halibrands. No spacers, lug changes required.

A friend of mine has Gordons Wilwood setup. 17", but not Halibrands, no issues.

If Gordon says they fit......they fit.

There are two different FFR Wilwood rear brake options. Not sure which one you have. The one that's been around for awhile is a 12.19 diameter single piece rotor and a single piston caliper/e-brake assembly. I can confirm that fits FFR's 17-inch wheels with no issue. Had that setup on #7750. The newer Wilwood setup FFR offers was released along with the 2015 Mustang IRS. 12.88 diameter 2-piece rotor and four piston caliper and separate e-brake caliper. Have this setup in my new build and can confirm fits in 18-inch wheels without modification. No experience with this setup in 17-inch wheels. Can only take FFR word that they need 1/8-inch wheel spacers when used with 17's.
