I have a few built cars right now.
Porsche 930: Running 10.64
Supra: 10.87
Corvette GS: 10.97
Clio V6: 10.86
So, I'm running a lot of 10's Problem is, I can't get any better. I have a Viper for top speed runs- it runs 260 without any issues. But I've never been able to get it to hook on quarter mile runs. It even spins into 4th sometimes.
