Best tune for Corvette ZR1

It’s my favorite car in the game and I really need to find a good tune for circuit and mostly drag. I have two Corvettes a super and a turbo. I managed to get more HP than the super but the problem with them is I get a lot of wheel spin. Please any help to get them better especially for drag and stop the wheel spin? When it comes to tuning, I’m a total idiot!
