Lets Tune Best Cars in all Classes

HI,

Pls post best tune setup for cars in all classes/types.

Let’s say:

Fastest Accelerating Car (maybe in class X,S2,S1) (Supra 98?)
Best Drag car to finish top in a 1/2 mile strip (Ultima GTR - 21 secs) or (maybe Alfa Stredale)?
Top Speed Car (Ultima GTR - 437 kmph)
