Assuming that you are looking for a brake upgrade because the current ones don't cut the mustard at track days. A couple of things to bear in mind.

Fitting bigger brakes will probably require larger wheels. The larger disks and calipers will need the extra clearence.

Forget cross drilled, if they have been drilled they will crack between the holes. I don't think proper cross drilled disks are drilled at all, I think they are cast like this.

If you are looking for real performance and quality, AP Racing and Brembo both make good kit. Alternatively, I have seen Porsche setups adapted for M3's.

Alternatively, run the standard setup with Ferodo DS3000's which have a coefficient of 0.6, most other track pads are about 0.48. These will crucify your disks and wheels, but you will never have brake fade and they stop fantastically well, I was outbraking Lotus elises even with warped disks. Additionally, fit a brake duct kit and you are sorted.

Roops.


looking at a brake job and was wondering what a good upgrade is and a good supplier. TIA--Al Read
