I know, I know... Tire Rack, but hoping to save some dough. Looking to spend $700 or less. M-parallels or some such BMW stock look in 17" and decent tread left would be ideal, but will consider anything as long as they're guaranteed to fit the e39 M5 rotors. Not too concerned with wheel rash, etc. Willing to pick up within 100 miles of Red Bank, NJ.
