I'm in need of a new set of front discs and pads due to a sticking calliper. Would appreciate any advice re: recommend suppliers for genuine / OEM discs.
indeed that is correct, 345mm for our machines... E46 M3 uses 325mm discs, I've seen a few of people buy the normal M3 discs and then get home and realize its smaller..
They are, I've just put some of these on mine today along with Brembo pads. The genuine rears I got don't seem as nice as the Ate ones which is odd I had to do quite a bit of cleaning up the carrier to get the new pads to fit properly though, so be prepared
I'm guessing it's the front/rear discs from Awesome (for £573), and the ATE/Pagid/Ferodo/Brembo/Textar standard perofrmance ones from CarParts4Less or EuroCarParts (for the other £100).
