Ok, just tried your 800pp Tuned Corvette for HSR. The car is unbelievable. In 5 races, I've won 4 and came in second in the other.
Again, as happened in Daytona Road, the Vette beats the Viper on every aspect: better speed, better cornering, and *really* better breaking. The difference is astonishing. I haven't tried a free run on it yet, but will beat my lap on the Viper easily.
Another thing to note here, is the gearing settings, that are very different from the Viper, specially the Final Gear setting (the ratios are fairly similar).
Thanks again for sharing you tunes. 👍
