If money were no object, I would go for Michelin Pilot Sports. I currently run Toyo Proxes T1-S. That was only because at the time I couldn't get Yokohama AVS Sports.

So, in summary, I would recommend AVS Sports.

As for Road Legal Slicks, dont forget that these Tyres wont last very long on the road as they have less tread than a road tyre to start with. VERY grippy though.
