Installed the GT350 front brakes. Please excuse the dirty wheels, I need to wash it. I got the black base GT350 calipers as I have the poverty-spec base brakes anyway, no need for red. Used all the Ford hardware, only changes were Powerstop Z23 pads and MMR caliper bolts instead of the Ford ones. Super easy swap, and they feel great. Plus they fill out the 20's nicely. One additional change I made was replacing the bleeder screws. I like to make service easier, so being able to bleed the brakes with just me, myself, and I was something I wanted. I'd been recommended the Stahlbus speed bleeders. They just replace the factory screws, get torqued into place, and I loosen the top bolt (under the cap) to bleed. No need to tighten, loosen, tighten, loosen and have a 2nd person. Got recommended these by a friend who tracks his Porsches so they stand up to more abuse than I'll put them through.
