Woo-Hoo!!! My stuff from Moto-Bins arrived!!!! (Actually, the shipment arrived yesterday, but I wasn't here to sign for the shipment, so I picked it up this morning at the post office.) The stuff got here MUCH quicker than I thought it would, too. Moto-Bins used their "premium" service, which apparently included Express Mail Delivery.
I got my rotor, Ferodo "Platinum Series" brake pads, and the new seat cover. A buddy of mine is going to help me install the rotor and pads tomorrow, and I'm going to see a local upholsterer about putting the seat cover on.
A question for those more experienced than I: Is there anything special I need to do regarding the rotor, like scuff the rotor up a bit with sand paper? Anything with the pads other than get the old ones out and fit the new ones in their place? I've got a copy of the BMW shop manual, but thought I'd ask anyway, since sometimes there are helpful tips by actual owners that the shop manual didn't include. I want this rotor and pads to work as well as they possibly can!
