Upgrade rear GT to 4 piston brembos

[TeeLew]

The craziest part is the single piston rear/6 piston PP front setups are proven equal to the GT350R performance maybe better in some configurations. If performance metrics of the 350R are what the op is after, that may be the ticket. 100% agree the single piston rear caliper is not flattering at all but apparently very effective.

To be fair, I doubt if the standard GT brakes are any different in terms of performance, once fitted with good pads and 2022+ discs. The pad clamping forces are the same for all of Ford's Mustang brake configurations (past base Eco) A greater number of pistons will general provide better pad wear, but it doesn't massively affect stopping power.

Changing the rear caliper will be more for aesthetics than any other reason.

you can get your parts list off the expensive new kits for sale then start sourcing used, salvage, reman, etc. from that. I don't see a way to not swap axles & knuckles for the gt 350 calipers. If you really have to go that route look at wilwood or baer, you get to keep your axles & knuckles. the front is a much easier swap.

The real answer is you do not need to change parts. The OP is looking for an answer that doesn't exist. There is no other "parts list". You can buy the full GT350R brake upgrade. A simple google search will pull it up. If you don't want that, too bad.

I'd honestly just take a look at this install guide for the 350R kit, then compile your list from the rear install. It'll give you the parts you need.

If you don't care to open that, here's the list from it for front and rear. I'll let you determine the rest for what you'd need.

Does the AP stuff have a parking brake?

No. the integrated handbrake cable into caliper is the problem. Other cars with a brake shoe & drum-type of rear hand brake are better suited for a conversion to 4-piston rear caliper.

OP.
You mean the kits that Full Tilt Boogie have on their website?
