Ooh, if you want something REALLY sporty then try some Toyo R888's. They're essentially road legal slicks. I ran them at Donington & am now going to run them for the summer on my light grey Monty 2's. In the dry, they grip like nothing you've experienced before - I was utterly amazed by them. And the beauty is............. They get even stickier when they've got some heat in them, too!! Downside is, they're only average in the wet, until you get some heat in them (which takes longer, of course).
(I run the F1's on some V6 4M Brands Hatch alloys for the winter months, BTW).
