Lfm Toyota Supra GT4 Cup Evo

TYRES

• Semislick compound, front 27.5 PSI cold / rear 27.0 PSI cold (target hot ~31–32 PSI front, ~30–31 PSI rear). No tyre blankets assumed — build temp gradually on out-lap.

ELECTRONICS

• TC: 3 (reduce to 2 once fuel load drops and tyres degrade past mid-stint)
• ABS: 4
• Engine Braking: Medium (if adjustable, mid setting — stock map otherwise)
• Brake Bias: 56.5% front (adjustable in-cockpit, move toward 55.5% as fuel burns off)

SUSPENSION

• // FRONT
• Ride Height: 60 mm
• Wheel Rate FL / FR: 62000 N/m / 62000 N/m
• ARB: 14000 N/m
• Brake Torque Multiplier: 100%
• Brake Bias: 56.5%
• // REAR
• Ride Height: 63 mm
• Wheel Rate RL / RR: 58000 N/m / 58000 N/m
• ARB: 11000 N/m
• Diff Preload: 50 Nm
• Diff Coast: 0.4
• Diff Power: 0.6

DAMPERS

AERO

• Front splitter: 2 (of available steps, car has limited range)
• Rear wing: 3 (of available steps — GT4 Supra runs modest downforce, favor stability over outright front end)
• Brake ducts: N/A if not exposed on this car — if present, set 3/6 front, 2/6 rear

KEY SETUP NOTE

• The Supra GT4's narrow diff range and modest aero mean the lap is won through the Dunlop/Bit-Kurve/Ford traction zones — run slightly more coast lock and softer rear ARB than you'd expect to keep the rear planted on throttle application without killing rotation into the hairpins; don't chase GT3-style rotation on entry, this car rewards patience on brake release into the Schumacher-S.

TRACK GUIDE

• Einfahrt Motodrom (T1): brake hard in a straight line before turn-in, this car's brakes fade late-stint — leave margin by lap 15+ and trail-brake only lightly, the GT4 doesn't like heavy trail with low-ish front grip
• Schumacher-S (T3): minimize steering input, use curbs only with the inside wheel, sacrifice a touch of min speed for a clean exit — exit speed here feeds the whole back section
• Dunlop hairpin (T5) and Bit-Kurve (T11): both are traction-limited — get the car rotated before the apex so you can unwind the wheel early and feed throttle progressively, diff power at 0.6 helps but don't abuse it with full throttle on entry
• Veedol chicane (T13): don't overslow it, this costs more on the long back straight than any time gained — use slight lift-and-place rather than full braking
• Ford-Kurve (T18): last big traction zone before timing line — get this exit right, it's worth more than any single apex earlier in the lap given the Supra's gearing
