Ok I need some help right now.
My Corvette Z06 is the best car I have in terms of everything. I could fly through the Gran Turismo Championship and Tuned Cars Events with it. However I've suddenly hit a problem.
I tried using my Z06 again for the GT Championship but it's doesn't have the same performance as before. My back wheels will start to spin out on it's own when I reach a certain speed and I'll go out of control and spin out, etc.
It's at 678 hp and it's got Sports Medium Tires on and I haven't tuned it for a long time but up until two days ago my Corvette started acting up.
So I took it to the GT Auto and rebuilt the Engine and replaced the Wheels but it wouldn't change a thing. In fact it made it worse. Now I can't accelerate past 320 km/h and will slow down a bit and just reach 320 km/h again. It used to go up to 350km/h I think with ease on a straight path.
What can and should I do?
