BMW M3 Forum (E90 E92) - View Single Post - Pad radial depth and unswept rotor issues?

ayao · 07-08-2018, 01:02 PM

I recently bought some new pads Raybestos ST45 (R2600 fitment) for a front AP BBK (caliper CP5060).

In spite of being a Google zealot, I have ended up with a set of pads that have a radial depth of 51mm which will leave a 3mm band of unswept rotor adjacent to the rotor hat.

I understand the theoretical risks of uneven temperature zones between swept and unswept zones that could lead to premature rotor cracking, but I'm wondering if anyone has actually experienced any problems with this radial depth mismatch.

Thanks.

(And incidentally, if anyone ever is looking for Raybestos pads for the Essex AP CP5060 caliper, it appears that the R2602 fitment is more correct than the R2600.)
