Rear brake upgrades - M135i 2 Pot Brembos fitted with installation video

Yes, good spot, I knew they were 4mm difference between the pairs but I started 2mm too large.
 
Interesting that your brakes are getting cooked. I didn't seem to have any fade on the stock M brakes with Hawk DTC70 pads, Castrol SRF fluid and Westersund's cooling ducts even on 100F+ days last season. Of course it could be track dependent, but even with the extra hp with the S54 in the M it was still fine. Anyways... looking forward to seeing where this ends up; could be useful (y)

It's only the rears I am talking about, and unfortunately, the 3.0si runs a smaller rear setup than the M, so it isn't a fair comparison.

Yours is 328mmx20mm 2 piece with a 78mmx54mm pad
The 3.0si is 294mmx19mm 87x37mm pad

The front 3.0si brakes are ok with the correct pad and cooling ducts.
