I've done 5 track days on my Diablo Corsas, and I must say: They are really great. The confidence in the front (from stock 60 to 70-profile) is mega (to use a foreign word). No more tucking sensations.
Also, while most of the others tyres looked ready for the bin, mine has just a bit of orange texture.
However, I would recommend keeping a fairly low pressure on the track, more or less regardless of track temperature 31psi front and 29psi rear was optimal for me.
Well, they are so great I've just gotten some Rennsports
Well I only ride track days anyway so why not go as close to slicks as I can...
