Mercedes Sls GT3

TYRES

• Slick Medium (M), front 24.5 PSI cold, rear 25.3 PSI cold (targets ~26.5–27.5 hot front, ~27.5–28.5 hot rear — the logged hot pressures of 23.8F/24.5R imply the lap was run cold/low-grip; richer 26°C air / 36°C track needs slightly higher cold fill to land mid-band hot). Optimal slick operating window: 85–95°C core temp for peak grip. No heat blankets assumed — build temp on an out-lap if session allows, otherwise setup must generate heat fast on a cold first flyer.

ELECTRONICS

• TC1: 4 | TC2: 2 | ABS: 4 | Brake Bias: 67.5% front (shifted 0.5% forward from recorded lap to load the front axle for max-attack late braking into T1 and Dunlop hairpin)

SUSPENSION

• // FRONT
• Ride Height: 55 mm
• Wheel Rate FL / FR: 145000 / 145000 N/m
• ARB: 120000 N/m
• Brake Torque Multiplier: 100%
• Brake Bias: 67.5%
• // REAR
• Ride Height: 60 mm
• Wheel Rate RL / RR: 130000 / 130000 N/m
• ARB: 90000 N/m
• Diff Preload: 60 Nm
• Diff Coast: 0.35
• Diff Power: 0.55

DAMPERS

AERO

• Front splitter: 2 (of typical 0–5 range) | Rear wing: 6 (of typical 0–10/12 range) | Brake ducts: Front 2 / Rear 2 (single flying lap, no need to overcool)

KEY SETUP NOTE

• The SLS's long wheelbase and front-heavy mass give huge braking stability but chronic entry understeer — on a single hot lap you must trade a touch of coast lock and slightly stiffer front ARB for rotation through the Schumacher-S and Veedol chicane, or you bleed more time there than you gain on the brakes.

TRACK GUIDE

• T1 (Yokohama-S): brake deep but straight-line only — SLS's nose is heavy, any trail-braking rotation beyond a light squeeze unsettles the rear; get it stopped, then rotate on throttle.
• Schumacher-S (T3): carry minimum speed through the first direction change and get back on power early for the second — the car's weight transfer punishes quick stab inputs here.
• Dunlop hairpin (T5) and Bit-Kurve (T11): both are pure traction corners — unwind the wheel early, feed throttle progressively; the diff power setting (0.55) is tuned for this.
• Mercedes-Kurve (T7): long rear-loaded sweeper — commit early with a stable mid-corner platform, rear ARB softness (90000N/m) keeps the outside rear planted.
• Veedol chicane (T13): sacrifice a fraction of entry speed for a clean, fast exit onto the back straight — this is the biggest straight-line gain on the lap, don't compromise it for one tenth in the chicane itself.
