DAMPERS

AERO

• Front Splitter: 3
• Rear Wing: 3
• Downforce Level: Low-medium, trimmed for the Mistral Straight
• Brake Ducts: Front 4, Rear 3 (heavy front end plus late braking at T1 and Beausset needs cooling, a small drag penalty is acceptable)

KEY SETUP NOTE

• The Mustang's rear is the limiter at Signes, so trim wing to 3 for Mistral speed but protect rear stability with ARB 6 and diff power lock at 0.75. Don't chase mid-corner rotation with the diff. Use the ARB and brake bias (59.5%) to rotate on entry, then let the high power lock and TC1 5 manage the V8 torque on exit. That keeps the rear tyres alive over a full stint.

TRACK GUIDE

• T1 Virage du Pont: Brake late from the end of the Mistral run-down, but trail the brake deep to rotate the heavy nose, then pick up the throttle progressively. Aggressive V8 throttle here lights up the rears, so use the TC1 5 buffer instead of fighting it.
• Chicane de la Sainte-Baume: Attack the kerbs. The stiffer rear ARB and 90 Nm preload handle kerb strikes. Keep the car straight over the apex kerb and square off the exit to carry speed onto the next straight.
• Mistral Straight: Slipstream and tow are key. Sit in the draft and time your out-braking move. Wing 3 and brake duct trim give you a speed advantage over higher-downforce cars.
• Signes (T14): Commit flat or near-flat. Do not lift mid-corner, as it unloads the rear and invites snap oversteer. Set the car on entry with a small trail-brake, then hold throttle steady through the apex.
• Complex de la Beausset (T15/16/17): Brake in a straight line first, then trail-brake into the first apex. Be patient on throttle through the sequence. Lap time is won on traction out of Beausset and the run onto the pit straight, not on over-driving the entry.
