Thomas: I took Dennis Olthoff's suggestion and installed the Avon CR6ZZ 215/70R15s and 295/50R15s on my ERA GT. I was a little apprehensive because I replaced 245s that were on the front with the narrower tire. I found out quickly that they work very well . . . no push when pulling max g. Very pleased with tires. They are expensive, but I only cried once. As for being too narrow, they work very well considering the light front-end weight of the GT40. After all, they are racing tires, but DOT approved.
