One of the Peugeot crashed hard in practice, they might back off some, and they didn't finish Sebring well. To finish first, you must first finish. the Corvettes have no real competitors in GT1, so you are correct there, The Porsche Ferrari battle will be the race to watch, I can't wait till next year when Rahall bring out the M3, then the big three will be at it again.
watch the Porsche RS Spyder for class win, and possible overall... the Audi's have been restricted buy rules and fuel...
