Can I make IS XTR brakes work with 185mm Avid rotors or will they only work with 180mm rotors?
Thanking you in advance.

Yes, you'll need to play about with the caliper bracket to get a little extra height.
I use my SLX brakes with Avid 185 rotors. Seems to work perfectly well even when the discs are hot.
I use the Avid IS to Postmount adapters (not sure if they're a different size to the shimano adaptors or if the avid calliper itself is a different size?)
They are 160 IS mount calipers. How do I get extra height out of them? ❓
You'll need an adaptor and erm you'll need to get ones which are +25mm F+R, hope might do them.....
I managed to file the bolt holes on my "180mm" adpator enough to fit a 185mm disc, there was plenty of metal on the adaptor tho (it was an A2Z one if it helps)
