Compatible brake options are 2015-2018 Mustang GT 14" front brakes (requires at least 18" wheels) and 2015-2018 GT Performance Pack with six-piston Brembos and 15" rotors (19" wheels recommended). The customer is responsible for verifying wheel fitment with larger brakes. This kit fits drum brake spindles and hubs on 65-73 Ford Mustang and Cougar. Note that 65-67 disc brake spindles are the same as drum spindles and require a V8 drum hub. Will NOT fit Granada or 68-73 disc brake spindles.

Questions & Answers
Q: What size wheels will I need?

Wheel needs scale with rotor choice - the larger the S550 rotor (14" vs 15"), the more clearance you'll need. Because wheel offset and spoke design vary so much, confirm fitment with us for your exact wheel before ordering the largest rotor option.

Q: Do I need to buy the 2015-2018 Mustang GT brake parts separately?

Yes - this is a bracket/mounting kit that adapts the S550-generation caliper and rotor to your 65-73 spindle; the donor caliper, rotor, and pads need to be sourced separately.

Q: Will my stock or upgraded booster/master cylinder handle these larger calipers?

The larger S550 calipers hold more fluid than stock, so most customers pair this kit with an upgraded dual master cylinder (and many add a power booster if still running manual brakes) to keep pedal feel firm.
