• ABS: 4
• Engine Map: 1 (race fuel map)
• Brake Bias: 57.5%
• Brake Driver: Not applicable in ACC (pedal sensitivity is a hardware calibration, not a setup option)

SUSPENSION

• Ride Height: 60 mm
• Wheel Rate FL / FR: 130 N/mm / 130 N/mm
• ARB: 4 (scale 1–10)
• Brake Torque Multiplier: Not adjustable in ACC (use Brake Bias)
• Brake Bias: 57.5%
• // REAR
• Ride Height: 68 mm
• Wheel Rate RL / RR: 120 N/mm / 120 N/mm
• ARB: 6 (scale 1–10)
• Diff Preload: 100 Nm
• Diff Coast: Not adjustable in ACC (preload is the only diff setting)
• Diff Power: Not adjustable in ACC (preload is the only diff setting)

DAMPERS

• ACC uses click scales (1–11), not Ns/m.
• Fast Bump / Fast Rebound: Not separately adjustable in ACC

	Bump	Rebound (click scale 1–11)
FL	Bump 6	Rebound 8
FR	Bump 6	Rebound 8
RL	Bump 5	Rebound 7
RR	Bump 5	Rebound 7

AERO

• Front Splitter: 4
• Rear Wing: 5
• Downforce Level: Medium-high, to stabilise Clearways and the Paddock Hill Bend braking
• Brake Ducts: Front 4, Rear 3. Heavy-nosed V8 with repeated hard stops on a short lap, so cooling is needed without a big drag penalty.

KEY SETUP NOTE

• The Mustang's front-heavy V8 will fight you on Paddock Hill's downhill braking and again on Druids exit. Keep the rear ARB stiffer than the front (6 vs 4) to control exit squat, but pair it with the 100 Nm preload. Too little preload gives snap oversteer when you stab the throttle out of Druids, and too much gives push into Graham Hill. Run TC2 at 3 to protect rear tyres over a long stint without dulling the aggressive rotation you want.

TRACK GUIDE

• Paddock Hill Bend: Brake late and straight at the crest, then release gradually and trail into the downhill apex. The car is heavy on the nose, so don't over-rotate with too much trail brake or the rear will step out. Use the full width on exit.
• Druids: Slow, tight hairpin. Prioritise a clean, early rotation and a straight exit rather than a late apex, because traction here feeds the entire Cooper Straight. Feather the throttle to stay within TC1 5 and protect rear tyres.
• Graham Hill Bend: Medium-speed left downhill. Trail brake in to rotate the front, lift slightly mid-corner, then go to throttle progressively. Aggressive entry works, but avoid overdriving or you'll scrub the fronts.
• McLaren Bend (T7): Sweeping right with sustained lateral load. Carry speed and avoid over-kerbing here, as hard kerb use will spike front tyre temps over a race stint.
• Clearways / Clark Curve: Exit speed onto the start/finish straight is critical. Sacrifice entry for a clean, early throttle application to maximise the run to the line. This is where lap time is most commonly won or lost.
