Its 24mm up front, and 15mm for a 91, so the 93 should be a mm or 2 thicker.

Lot of info, but don't see min. thickness.

min thickness on the front is -2mm and -1.5mm rear

So 28mm front and 20.5mm rear, right? Thanks!

Well, if you look at the 91/92 minimum thickness's, its 24 up front, and 15 in the rear. (Got these specs from my BGB)

According to the info Oteck posted, that would be -1mm front and rear. It COULD be different though for the 93's.

The rotors are different.

I know the rotors are different, but are the standard to minimum specs different between the 91s and 93s? For the 91's, after 1mm of wear, they should be replaced, and according to Oteck, after 2mm of wear on the 93's, they should be replaced.

Its possible that the 93's can take more wear, since they are thicker to begin with. As long yours arent borderline, you have nothing to worry about.

Thanks. Looks like I'm in good shape for now, then.
