The RSR's get really good reviews. I have never used them so cant comment although plenty have.

On my race car I have been running yoko's A048's although I have found them quite a tricky tyre to keep in the "sweet" spot.

Have used Michelin Cups for years and are still the tyre of choice for the road car when on track.
I have Michelin Pilot Super Sports fitted to the road rims and they are pretty good as well.

Lots of choices and huge variations in price. good luck....lol
