"I, Tamara, do solemnly swear that I will spend my paycheck wisely on BMW brake rotors, rather than blowing it on frivolous things like antique rifles, gourmet beer, and books."
...but I've gotten so good at avoiding using the brakes (the front rotors are so warped they probably look like Ruffles potato chips) unless absolutely necessary the last couple months. A spin down Mourfield the other day was such a symphony of downshifts and engine-braking that it sounded like the soundtrack from the next release of Gran Turismo.
I could get Brembo OEM replacements from Tire Rack for $170+shipping, but I have neither the time, talent, tools, or tarmac to swap them out. Hopefully I can weasel an appointment at Gillespie this Friday... (That's a VFTP endorsement of Gillespie, BTW; I've been using them since I bought the Beemer five years ago, and have had uniformly excellent experiences.)
