congrats in advance on the cat.
i have the 10 inch campys on mine. the rears are deeper than the fronts. i threw a set of 295 bf goody radial TAs on mine. they're not rated for anything over 105 mph but they only cost me $120 a piece. i never really took the car much past 130 mph anyway. the car is a 74.
with the cheaper tires burnouts become more affordable.
