I would not recommend RSA'* to anyone considering them unless they are using a REALLY crappy tire now. We have RSA'* on the SSEi and GTP. We have already replaced them on the SSEi (at 50K because they were gone), I think it was $600, and since we know the guy that owns the tire place we got the tires at cost, if we would've paid full it would've been like $700. They have no performance at all. They have a crappy ride, crappy handling, and they just spin like mad at lower than 30 (and lower than 45 on the GTP). If you are going to spend that much for a tire, get a good tire. RSA'* are rated to 130MPH, LS'* are to 110 IIRC. The GTP is getting Eagle F1'* or the Equivelant that Bridgestone sells (can't think of the name right now) probably by 30K, at 18K the tires are fairly bald already and I'm not just talking about the front tires. We want a performance tire for the GTP, that is why we are going so expensive with the tire, but just get something a little nicer than RSA'*. I don't think RSA'* are good tire at all, and we have them on 2 cars, not to mention they don't look good either.
