DAMPERS

AERO

• Front Wing: 3 clicks
• Rear Wing: 4 clicks
• Downforce Level: Low-medium (prioritises banking and backstretch drag, retains rear stability)
• Brake Ducts: Small (front 2 / rear 2), minimum drag for a single lap

KEY SETUP NOTE

• The 31° banking loads the suspension heavily and tends to compress the rear, so rear ride height and stiffness have to keep the platform stable. The Bus Stop and infield need front-end bite. A slightly stiff front ARB with soft rear and low Diff Power (0.3) gives rotation on entry while the diff stays progressive enough for traction out of the infield.

TRACK GUIDE

• Bus Stop chicane: This is the biggest braking zone. Brake late and hard at 100% pressure, trail the brake into the first apex to rotate the nose, then pick up the throttle early on the exit kerb. Rear bias 42% allows hard rotation without locking the fronts.
• Infield section: Use the kerbs aggressively through the medium-slow turns. Prioritise exit speed over entry speed, because every corner leads to a straight or banking and traction is key. Be patient with throttle application and avoid wheelspin.
• Banking (T3/T4): Keep the car tight to the low line and stay flat or nearly flat. The banking loads the car heavily and gives huge grip, so don't lift. Smooth steering inputs avoid unsettling the rear.
• Backstretch: Take the slipstream line if available. Set up the exit of the final infield corner perfectly, since speed carried onto the backstretch compounds over the whole straight.
• Final chicane: Brake deep and straight, carry minimal speed through the chicane, and get the car pointed before throttle application. Exit speed onto the pit straight is critical for the next lap's start and finish line speed.
