Man, I have tuned up some pretty sweet cars.
My C1 Vette turned out better than I expected. I swapped the ZR1 motor in (the C2 ZR1, not the C6) and with max weight removal + max tires and a good suspension setup it is actually rather fun. It's tricky, as it is a bit tail happy, but decently fast and fun to drive.
The C2 Stingray turned out amazing, and I just tried it on a whim. Also with max weight removal, max tires & rear downforce, it is downright amazing. It understeers a good bit of course, but the rear sticks like glue and surprisingly, the stock 4-speed tranny with the monstrous engine work REALLY well together.
If anyone wants the tune for these cars, let me know. I am just that surprised on how they turned out! Then again, I hadn't ever tried the Stingray. And of course all of my cars get the full suspension upgrade. Also, neither of the motors had power upgrades.
Lastly - I will definitely be racing, but may be delayed a bit or drop out for a race. My fiancee is going to make some grub when she gets home, which should be sometime around 9pm EST. So I will need to get mah eatin on, and I need to drop by 10pm either way. But we will definitely get some races in!
