Lfm Toyota Supra GT4 Cup Evo

TYRES

• Compound: Semislick (GT4 control tyre)
• Front: 27.0 PSI cold, settling at ~30.0 PSI hot (target the middle of the in-game tyre app optimum band)
• Rear: 26.0 PSI cold, settling at ~29.5 PSI hot
• Tyre blankets: session option, assume OFF. First flying lap is a warm-up lap, so the cold values above are deliberately tolerant.
• Camber: Front -3.4° / Rear -2.4°
• Toe: Front +0.05° (slight toe-in for stability under hard braking) / Rear +0.20°
• Caster: 7.5°

ELECTRONICS

• TC: 0 (car has no adjustable TC scale)
• ABS: 0 (car has no adjustable ABS scale)
• Engine braking / brake magic: not adjustable on this car
• Brake bias: 59.0% (in-cockpit adjustable, see Suspension)

DAMPERS

AERO

• Front splitter: 2 (of 0-5)
• Rear wing: 5 (of 0-10), a mid-range wing for the long Esses and Boot flat-out sections without costing top speed down the back straight
• Downforce level: low-to-medium (GT4 car, narrow range)
• Brake ducts: not applicable / not adjustable
• Fuel: size to stint, roughly 2.6 L per lap at Watkins Glen Boot (about 3.8 mi / 6.1 km per lap) for race distance. For a 12-lap race, load ~34 L (including a 2-lap reserve). Adjust proportionally for your race length.

KEY SETUP NOTE

• Watkins Glen rewards high-speed stability and a stable rear through the Esses and the Boot. The aggressive style wants rotation, so use the rear diff coast (0.3) and a slightly softer rear wheel rate than front, but keep the front toe at +0.05° and caster at 7.5° so the car stays settled at the long, fast, late-braking entries. The gentle front pressure bias helps keep the front tyres from overheating during the long Back Straight to Turn 1 braking zone, preserving the fronts for the full stint. Because blankets are off in-session, the cold pressures are chosen so the tyres reach their optimum band within the first 1.5 laps rather than spiking over target.

TRACK GUIDE

• Turn 1 (end of the long front straight): the heaviest braking zone on the lap. Brake late, but stay disciplined with trail-braking pressure so the front doesn't lock and flat-spot the semislicks you need for the entire race.
• The Esses: rhythm over aggression. Use the kerbs on the apexes sparingly, as they upset the car at speed. Get the car rotated on corner entry, then commit to the throttle early in each change of direction to keep momentum through the full sequence.
• The Boot (the signature section): carry as much speed as the tyres allow through the first part, then brake and rotate hard for the tight Boot hairpin. This is where late braking pays most, but a poor exit costs lap time all the way down the next straight, so prioritize a clean, early throttle application on exit.
• Traction zones: out of the Boot and the final chicane, use smooth throttle with the 0.5 power lock. Aggressive throttle before the car is straight will overheat the rear tyres, which hurts you late in a stint.
• Race management: over a full stint, the front-left tyre takes the most punishment. Back off the aggression slightly in the last third of the race (earlier lift, less kerb abuse) to avoid a late-race pace collapse.
