FYI, I've seen reports of problems when running Shimano calipers with other rotors (and vice versa). Sounds like the Shimano rotors are slightly different size than other manufacturers, which has caused problems for some, but not for others. There is a long ongoing (boring but informative) discussion about this in the Brake Time forum you might want to check out: https://forums.mtbr.com/showthread.php?t=286460
Sorry if slightly off subject, but I recently replaced my whole brake system with the Avid Elixir CRs, and they are awesome. Fastastic function/form and decent price---and the black carbon w/ red anodized metal looks damn good on the Mojo if you have the black/red motif going.
When riding, the 08' XT rotors on my Ibis are usually turning fast enough that I cannot tell if they are XT or XTR...so, just don't stop and look at your rotors...
This July, I replaced the worn out XT brake pads (composite pads) with an aftermarket brand of Sintered Metal pads....(the XT pads by the way fit XTR brakes). The original composite pads lasted barely 4 months. The replacement sintered metal pads clearly have more bite, last longer and are quiter when wet ....which it is all winter on the Wet Coast (Vancouver Island)...So, I have no suggestions to make the bike "look better" ,but at least it "stops better".
I like the Marta SL rotors made by Galfer for style and performance. Kind of expensive at $60 retail, but worth it for long wear, noticeably more power to modulate without lockup than other rotors changing nothing else (I've compared Hayes and Formula rotors to these), excellent in mud, and quiet.
You'd need a CenterLock hub to 6-bolt rotor adapter, there are many brands available. Although ugly but probably well hidden, the Problem Solver brand looks like it would not have any spline slop issues.
