Some of you know my 357ti build, others dont, but it consists of a 5.7L aluminum v8, 6 speed transmission, 4.10 limited slip, 245f/285r, carbon fiber roof, diffusers, and a bunch of other crap. Recently, i started looking into rear brake options and nothing quite tickled my fancy, so i went off in nowhereville and created my own.
As it sits, it has the E36 m3 front brake upgrade installed, front the non-vented front brake setup when i bought the car, and the stock non-vented rear setup. Purchased some brakes from a Mercedes CL600 a few years back and it just sat in the box every since...dual piston rear, quad piston front. Dusted them off and got to work.
The rear calipers are all aluminum, dual pistoned, and have the mounting tabs built into the caliper and are also lighter than the ti rear caliper by itself. The mounting tab bolt spacing is obviously incorrect for the ti as well as its offset for the rotor, so a custom bracket had to be created as well a proper rotor and offset. I just so happened to do a set of brakes on a 128i and had a front rotor in my possession, which had a high hat area, just like the ti rear. I test fitted and the results are below.
