Audi RS 4 Avant
Forza Horizon 6 rally tune for the Audi RS 4 Avant. Springs and dampers are calculated from the car's mass and weight distribution — not copied from someone else.
On dirt the frequency is roughly half of tarmac. Soft springs and high ride height keep the wheel on the ground — a tarmac setup skips and bounces off-road.
Tire Pressure
starting pointThe direction is reliable, the number is not. Correct against your hot pressure target after a lap or two.
Gearing
starting pointNo stock gearing data for this car — showing the discipline average.
Alignment
starting pointTelemetry reports one temperature per tire; the inner/middle/outer split only exists on the in-game screen. Verify camber there.
Antiroll Bars
starting pointNOT CALCULABLE. Forza exposes neither track width nor roll centre height, so roll stiffness cannot be derived. Published sources disagree on these numbers by up to 5x.
Springs
calculatedDerived from mass and weight distribution via K = M(2πf)². Shown in lb/in because Forza's metric spring unit is wrong — it computes per centimetre but labels per millimetre.
Damping
calculatedFrom critical damping: C = 2√(KM). Bump is 62% of rebound — four independent sources land on the same ratio.
Aerodynamics
starting pointApply if the car has adjustable aero, otherwise ignore.
Brake
starting pointSources flatly contradict each other on brake balance (46% vs 62% for drift). Tune this one by feel.
Differential
starting pointDifferential lock cannot be derived; this is the community starting value for the discipline.
