For oversize front rotor, I've been pleased with the Tusk from RMATV I put on my 11. I no longer feel the front brake is weak. In fact I've entered many a corner at various lean angles, hard on the brakes with the rear wheel off the ground and still felt in control. That's with OEM pads too.
Other than suspension, I'd just ride the bike. Get used to and adapt to the differences from your RMZ, then ride some more.
