I have them on my car now. They really suck, except in the rain in which case they are awesome. I know that no tire has a sidewall that is as stiff and RE070's, but these things are ridiculously squishy. They grip just fine, but you have to run really high tire pressures to not get the tire to roll over on the sidewall when cornering hard. I really think that if BFgoodrich stiffened up the sidewall, these tires would be awesome. Till then, don't bother.
