I have the James Bond Bridgestone tires on my ZR1 on my RSR wheels. The short limited time I was driving on them late Sept/early Oct. they seemed fine but I'll have to wait till next spring/summer to see how they really are grip wise on the street.
On only a street application, this tire will be no better or worse than an equivalent Michelin ZP PSS tire and both will be better grip wise on the street when compared to a Cup 2. Cup 2's don't grip unless you get some major heat in them like on a track. Driving on Cup 2's on the street you will never get enough heat in them for the best grip they can provide.
