i have 750 brakes all around (same diameter but 28mm thick in front instead of 22mm and vented rear, because i used e32 rear i swapped trailing arms to deal with the different offset on the caliper/rotor) i have done several 100+ mph stops and they work real good, i like ate gas slotted front discs and have installed them on almost everything i've owned, they do have a better bite on the pads. i like the m5 thrust arm bushings, they have a small air gap and are not totally solid
all america wants is cold beer warm cat and a place to take a poop with a door on it
