Yeah, it probably looked a lot like that. I actually have been lifing my tire with BFG KDW's on the car. I don't have any photo proof, but I have had numerous people tell me. My friend also autox'd my car once and I saw him lift the rear wheel on the KDW's so it should happen a lot with the race tires.
R1's were nice tires. Built in negative camber. I wish Kumho would do that.
