Im sure there grade 4 mate, im not 100% though mate as i let Monster Motorsport get them for me. Yeah its crap mate, just gets me down from time to time especially as i try my hardest to keep it in perfect condition. Its a daily driver though so it cant be helped i suppose. And yeah matey of course, any time!! You getting new rubber for the Rays or are you using the Toyos off the Speedlines?
