Supra Brake Piston Dimensions

[zackarybyrd]

Does anyone know the exact dimensions of the brake pistons in a stock GR Supra with the 348/345mm rotors for both the front two and rear? I am discussing a project with a colleague and I don't currently have my car because it's in the shop.

I think you probably would have put that in the response if you did but I have to ask.

If you look at the back of the brembo calipers, they're all embossed with the piston sizes and rotor dimensions. Funny enough, even if you jump up to the 374/36 rotors, the larger calipers are still 40/44 pistons. Just the caliper body is larger.

Go on rock auto or eBay and you can find replacement parts and rebuild kits. Just look for any caliper on a 340i/440i/540i/740-750i, etc...
