recomended tyres for road/track

[miles]

RSR's (Track day tyre version) are plain **** even for the money, No grip, braking performance is terrible, Only thing is traction in a straight line was OK, Were not talking a few feet but a huge margin here, Compare them with the Silverstone's I swapped him onto he found over a second, this is on a 39 second run to give you a idea and I was a shade under 2 seconds slower with them on
