Okay, had my L for 8 yrs. now and have changed everything under the sun! Last year I put on the 15" Bogarts and obviously had to grind the Sh#@!t out of the stock calipers to fit. Problem is they really overheat due to thiness of metal now. Has anybody out there downsized their rotors and calipers to, say, 15" or 16" to accommodate the smaller wheels without all the grinding and "thinning" of the calipers? I think I would trust smaller brakes more than the larger and "thinner" calipers caused by the grinding. Thanks, Jack
