DAMPERS

AERO

• Front Splitter: Level 2 (of adjustable range)
• Rear Wing: 4 (medium-high downforce for Spa's high-speed corners, trading some straight-line speed for Eau Rouge/Blanchimont stability)
• Brake Ducts: Front 3 / Rear 2 (open enough for long-run heat management)

KEY SETUP NOTE

• Spa punishes a loose rear through Eau Rouge–Raidillon and Pouhon — run slightly more rear wing and a touch of extra rear ARB stiffness restraint (softer than front-biased instinct) to keep the GT4.R planted on corner entry at full commitment, while retaining a diff setup (0.5 coast) that allows rotation into Les Combes and the Bus Stop chicane without snap oversteer on trail-braking.

TRACK GUIDE

• Eau Rouge/Raidillon: full throttle commitment requires a stable, flat rear — don't lift; trust the setup's rear wing level and ride height to keep the floor sealed.
• Les Combes (T5): heavy braking zone from high speed — brake in a straight line, late apex to open exit for the downhill run to Pouhon.
• Pouhon (T9-10): a lap-defining double-apex left — carry speed, trail-brake to rotate, unwind steering progressively; mid-corner stability here separates fast laps.
• Campus/Stavelot sequence: traction-sensitive exit onto the Kemmel-adjacent straight — get the car pointed early, avoid wheelspin with 0.6 power diff setting.
• Bus Stop Chicane (final corners): late apex the first part, sacrifice entry speed for a clean, powerful
