Product Information

If you drive a 2015-2018 Ford Mustang, EcoBoost, GT, V6 (2015-2017), or GT350 (2016-2018), these are rear pads built around Hawk's High Performance Street ceramic compound. The job is simple: more bite at the pedal without turning your Mustang into a track-only ride.

Why Upgrade to Hawk HPS Rear Pads

Per Hawk, here is what the HPS compound changes:

  • A higher coefficient of friction than stock pads means more bite the moment you press the pedal.
  • Hawk's own figure: 20 to 40 percent more stopping power than most standard replacement pads.
  • Higher resistance to brake fade than most standard replacement pads, so the pedal stays consistent instead of going soft on repeated hard stops.
  • Less brake dust than you may be used to, so your wheels stay cleaner longer.

Fitment Notes

These rear pads fit the 2015-2018 Ford Mustang: EcoBoost, GT, and V6 (2015-2017), plus GT350 (2016-2018).

Install and Honest Talk

These are rear pads only. If your front brakes are still running stock pads, the extra bite and fade resistance Hawk describes only fully shows up at the back axle, so the overall stopping-power upgrade you feel will be smaller than it would be from swapping the whole car. Hawk also gives that stopping-power boost as a range, 20 to 40 percent over most standard replacement pads, not one flat number, so where you land depends on your specific setup. The source copy doesn't say what hardware or shims ship with this rear application.

No Robots. Just Car People.

Buying parts for your Mustang or F-150 should not feel like homework. Too many stores bury you in a giant catalog, slap the same distributor description on every product, and leave you guessing whether it even fits.


We do it the other way. We carry the brands you already trust, we tell you what a part actually does, and we give you the truth about the tradeoffs before you spend a dollar. Drone on that exhaust. Ride quality on those springs. Whether you need a tune. The stuff the big catalogs leave out.
