Dax, if you need help leveling the cars, I can pitch in.
One thing I noticed this season, or last season, was that you didn't quite keep the cars all in line. That may not have been possible because of the weight being so different.
The Corvette is a horrible car stock, but when you tune it, and tune it again, and keep tuning it, you can eventually get it to keep up with the others, if they're not fully tuned. If all the cars were fully tuned, the Corvette wouldn't have a hope last season.
This season, you're going to have to be much more careful with the cars, because some cars have different transmissions (six speed, seven speed). The seven speed, when set up correctly, can be significantly faster and can gain more than an extra second.
I would suggest tuning all cars to what's close to an optimal tune (again, transmission), then leveling them with horsepower.
