The standard pads arent fit for track work

Something i do find strange tho is that the 135i and the 130i came with optional 6pots?
Id like to know why the M3 and 1M get a lesser caliper than the 130i? lol

Has anyone gone the route of the CSL guys and fitted AP 6pots up front and 4pots at the rear?
If the 6 piston caliper that came on my 135i was as good as the 1M caliper, I wouldn't have had to replace it with a BBK. Number of pistons is like number of cylinders. 6 pistons is sometimes better than 4 or 2 but not always, just like 8 cylinders is sometimes better than 6 but not always.
