Depends what you want to spend. I've had heaps of tyres, and done track days on most of them, in cars ranging from M5's to a 1.6NA MR2. In the middle price range, I'd toss-up between Pirelli PZero-Nero, Michelin Pilot Preceda, and Yokohama ES100. Toyo T1-S were good on the smaller cars, but no idea what they're like on big fat cars like ours. Up the spending a bit, and look at Bridgestone S-03's, Yokohama AVS V102 (AWESOME tyre currently on my xr), Pirelli PZero System Assimetrico (Giallo)... Michelin Pilot Sports. Tyres NOT to get: The goodyear Eagle F1's sucked on the track. Every Hankook/Falken/Nankang etc tyre "as good as X brand!" always suck. The people who say they are good also say the stock Dunlop 3000A's aren't bad. Which of course, once you've driven on a real tyre, you'll realise the stock ones are bloody awful. Cheap though. You won't be unhappy with any of the tyres I recommended above.
