The pads I received were actually for the SSBC front calipers. When I inquired about this (to SSBC directly), they stated they use OEM pads for the rears, not some "performance" friction material. I will experiment with pads until I find a combination that works well for me but it was disappointing.

Just a quick note to say what great people (Eddie Davis) are at Latemodel Restoration. I ordered and bought a set of Track Pack Wheels for my 2014 Mustang GT.Their prices and service is the BEST in the MUSTANG INDUSTRY, not only the price and service but the honesty. The wheels came thru with the wrong center caps one call to Eddie Davis corrected the situation in one phone call and the next day I had the center caps (FORD RACING) the correct ones no BS, they just did the Right Thing,whereas in this Day and Age you don't here that often.
