At least in 97 and in 00 it depended on what tires came with the car. My 97 V6 had H rated tires if I remember right. In 2000 it was possible to get a Z28 with the similar tires and have a 118 limiter. Otherwise they were limited to around 160. Of course my Z28 has no limiter since I had the software and cables to change the computer [Muaha]
The curb weight is huge, so far that is the only thing I really wish they could have changed. Drop a couple hundred to 500 pounds and they would do so much better.
I'm going to put some miles on the car but hopefully in August take it out to Bandimere for test & tune. I'm thinking mid to high 15's based off of sea level numbers.
