I wouldn't be buying any more slicks..... we run on them up here. The only event we use grooved tyres for are the Nationals. They have advantages and disadvantages. Yes they provide more grip when they are hot, but if they are cold they are very slippery...... definitely slower than grooved until you get them hot, which could be a couple of laps. It's not just a case of bolting on slicks and going faster. The suspension works differently too. Have to change toe in and camber caster etc to make the most of it.
