Get Toyo RA-1's and call it a day. If you can wait until the LeMans event at Mosport, contact Clay at Bimmerworld and see if he has any used ones he can bring to the event.
"Driving is like a narcotic, an addiction that can take over lives. It ruins people, breaks families apart, and even kills. Itís habit that needs to be fueled. Time, money, rationality, sweat, knuckle skin, and anyone who disapproves are of little importance to a driver, and are often overlooked. Hi, Iím Nelson, and Iím a drivaholic."
