3.0si brake upgrades
Read a few threads with nothing conclusive (or very old) - I have some really degrading calipers (rusting, filthy, shoddy), and was considering upgrading.
At the same time, my rotors are very worn and are reaching their thickness limit.
I'm not looking to upgrade to an expensive BBK, but seeing that the Z4M uses 345mm front / 328mm rear, was hoping I could do a direct bolt on/upgrade. Unfortunately, neither front nor rear spindles fit the Z4M (from what I read).
My next best option was to upgrade to 135i front rotors/calipers. Can anyone confirm this fits our front end?
As for the rear, shame not much available for our cars...
