Sorry to hear about the defect, I also got pulled over on the weekend with the cop saying I didn't have enough clearance between the inner gaurd and the tyre on the rear, and if something got flicked up inside the gaurd it could spin me out , only a caution though.
More to the point, I have a set S1 wheels with near new tread which I used to get my car through.
PM me and we can organise something, or grab my number off Adam as he contacted me in regards to the wheels.
