Any suggestions to tune my car for the Supercar Festival

[Dangerman_1973]

I currently have the Chevrolet Camaro LM Race Car and the S Nissan GT-R Concept LM Race Car.

Any suggestions for tuning these cars so I could win the race?

They shouldn't need any tuning at all, would have thought both would win comfortably at stock settings.
