Finally got a chance to try out some used (read: old but untouched) R3S03 Hoosiers that I picked up a while ago. They came on a set of black Fikse FM5 classics (17x9.5/10.5) and look fantastic on the car. Once they were scrubbed in I gained about 2 sec from my normal A048s which was good for a 1st place finish. I’m glad I had a tire warmer (co-drive) to scrub them in, they would have been a bust otherwise.
