Im looking for a sort of stunt setup.
For any of the gtr cars apart from the little hatchback.
Im looking for sort of a setup where when i enter the corner and sort of drift the car flips over.
Is there anything like this? Or maybe even just one where when i turn the car it flips over sideways?

Well the XFR / UFR is used for these the most because they are top heavy. The others need to have help by a curb or something. Best bets is to maximize grip on your tires when means use the softest compound and lower the pressure. As far as springs I am no expert on those yet and still always refer to a guide I have at home to helping me with that - can't wait till I have it memorized but until then.

Max spring strength, max spring length, max negative camber, min/very low tyre pressures. Should be enough for the UFR at least.

i used positve camber once... so the ufr can flip easier

I have no problem flipping ufr on normal racing setup

Ive only tried your so far, but it works with all the hatchback cars.

There u go
