I have done a LOT of research over the last few years, looking for the stickiest road legal tyres. As tyre companies are not keen on disclosing the mu value (coefficient of friction, basically) of their tyres this has been difficult.
I have found what I think I am going to use, but for normal sizes and track cars the popular choice seems to be between Toyo and Yokohama. Pays your money and takes your choice. Unless you are looking for ultimate performance, you won't go wrong with either make, or, for that matter, various other makes with similar performance.
