The standard brake on the BDR will be up to the task if you do a couple of things first change to Performance Friction Full races pads you can get them from Bimmer World applications is for non-M E36. Second change the fluid to Castrol SRF or ATE Super Blue brake fluid. As for options Rick Lake is absolutely correct about the ACCUSUMP with my old motor before I installed an Accusump I could watch my
oil pressure drop to 1/2 B.A.R in high G turns....As for the electric PS pump Reg has a few cars that have it on the street but haven't yet done one for the track... This is my next up grade....Mike
