I actually have an E24 but my 79 Euro has much in common with your early E-12 vehicles. I was wondering what brake upgrades you all have done on the earlier E-12 cars. I know on the E-28 you can put the 540 calipers and such in but I have not heard anything about what can be done to the E-12 brakes. Also any suspension upgrade info would be greatly appreciated as well.
