I'm not the right person to give tyre advice for slick tyres. If it was semi's I'd suggest the Dunlops or Advans like mine - or even the Hankooks that seem to have cleaned up this yr at Superlap. Need a circuit racer for that kind of knowledge! Power to weight wise I can't see why you could get your car into the 1:05 range at WP. Even better if you drive as well as you vision!
