I have 4 brand New 225/45/18zr Bridgestone Potenza S-03 Pole Position tires. (NEVER USE) I bought it brand new on tirerack.com I just sold my M3 and have no use for them unless I buy some 18 in rims. I would say the S-03 is the best tire for handling. The tires costed me around $900 with shipping. My loss your gain. I am from the bay area. Selling for $675 FIRM!!!!!!!!!!
Pick up in the Bay area PLEASE!!!!!!!!
