Hi Due to the lack of R1s, I am about to purchase the Toyo Proxes RA-1. This is billed as a race tire. These will be my drivers school tires to replace the worn out R1s. Has anyone out there got any track experience with this model??? Feedback please. Don Stevenson/BMWCCA Boston Chapter (1988 325IS, no power steering, cracked foglights) ------------------------------
