Questions & Answers
Q: What wheel size do I need for these calipers to clear?

17" or larger wheels are required to clear the 13" S550-based rotor and caliper package.

Q: Which rear axle does this fit?

It's built for 8" or 9" rear ends using the small rear wheel bearing (2.835" OD). Double-check your bearing size before ordering — large-bearing 9"/8.8" rear ends need a different mounting kit.

Q: Do I need to buy the 2015-17 GT rotors and calipers separately?

Yes, this listing is the mounting bracket kit that adapts genuine or aftermarket 2015-17 Mustang GT 13" rotors and calipers to your classic rear end — the rotors/calipers themselves aren't included.
