Aston Martin Valkyrie

Forza Horizon 6 circuit tune for the Aston Martin Valkyrie. Springs and dampers are calculated from the car's mass and weight distribution — not copied from someone else.

Drift Circuit Rally Drag

On circuit the front/rear balance sits close to neutral. If FH6's new Mechanical Balance readout is around 0.60 your bars are right — correct any drift with the bars.

Tire Pressure

starting point
Front 31psi
Rear 31psi

The direction is reliable, the number is not. Correct against your hot pressure target after a lap or two.

Gearing

starting point
Final Drive 3.3

No stock gearing data for this car — showing the discipline average.

Alignment

starting point
Front Camber -1.8°
Rear Camber -1.2°
Front Toe 0°
Front Caster 5.5°

Telemetry reports one temperature per tire; the inner/middle/outer split only exists on the in-game screen. Verify camber there.

Antiroll Bars

starting point
Front 30
Rear 32

NOT 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

calculated
Front Springs 349.7lb/in
Rear Springs 565.7lb/in
Front Ride Height 3.7in
Rear Ride Height 3.9in

Derived 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

calculated
Front Rebound Stiffness 11.6
Front Bump Stiffness 7.2
Rear Rebound Stiffness 12
Rear Bump Stiffness 7.5

From critical damping: C = 2√(KM). Bump is 62% of rebound — four independent sources land on the same ratio.

Aerodynamics

starting point
Downforce maksimum

Apply if the car has adjustable aero, otherwise ignore.

Brake

starting point
Balance (front) 52%
Braking Force 100%

Sources flatly contradict each other on brake balance (46% vs 62% for drift). Tune this one by feel.

Differential

starting point
Acceleration 45%
Deceleration 25%

Differential lock cannot be derived; this is the community starting value for the discipline.
