Lfm Toyota Supra GT4 Cup Evo

TYRES

• Semislick compound, Front 29.5 PSI cold / Rear 29.0 PSI cold (target hot ~31–32 PSI front, ~30–31 PSI rear). No tyre blankets assumed — expect first lap to be a warm-up build lap before the flying lap.

ELECTRONICS

• TC: 2 (minimal intervention, allows rotation on throttle)
• ABS: 3 (moderate, trail-braking support into Zolder's heavy stops)
• Engine Braking/Brake Magic: not adjustable on this car (fixed GT4 ECU map)
• Brake Bias: 58% front (see Suspension section for exact in-cockpit value)

DAMPERS

AERO

• Front splitter: max (step 4/4), Rear wing: 4 (of 6) — Zolder rewards a touch more rear stability over top speed since the chicanes and final corners demand confidence under braking and on exit; downforce level moderate given GT4 ceiling.

KEY SETUP NOTE

• Zolder's combination of a long back-straight braking zone into the chicane and tight final corners means this GT4 Supra needs a stiffer front/softer rear balance to rotate confidently on entry without sacrificing straight-line stability for the kink before Start/Finish — slightly higher rear ride height and softer rear ARB help here versus a pure low-downforce track setup.

TRACK GUIDE

• Turn 1 (Butte): brake late in a straight line, trail into the apex — this car's semislicks grip well on initial bite, trust the front.
• Chicane before the pits (Kleine Chicane): sacrifice a tenth on entry speed for a clean, early throttle exit — this leads onto the longest flat-out section of the lap.
• Terlamenbocht (final corner complex): carry max minimum speed, this corner dictates straight-line speed on the pit straight — do not overslow it.
• Traction out of the hairpin (Jochen Rindt): get the car rotated early with a late apex so power can go down in a straight line, this is a key lap time zone given GT4's modest power.
• Kerb usage: Zolder's curbs are aggressive — attack them cautiously on entry kerbs (risk of unsettling the GT4's relatively soft suspension) but use exit kerbs fully for track width.
