Toyota GR86

TYRES

• Street-compound slicks (GR86 fixed Toyo RR), front 32.0 PSI, rear 31.0 PSI (hot target 32–34 PSI all four once up to temp). Optimal operating window 80–95°C — single hot lap, aim to generate heat fast through opening sector before Motodrom.

• ABS: N/A (stock brake-by-wire not user adjustable in GR86 — leave default)
• Engine Braking: N/A (fixed drivetrain, no adjustment)
• Brake Bias: 58% front

DAMPERS

AERO

• No adjustable wing on stock GR86 — fixed small ducktail spoiler, no front splitter adjustment. Brake ducts: N/A (not adjustable this model).

KEY SETUP NOTE

• The GR86's low power means mechanical grip and momentum through the Schumacher-S and Mercedes-Kurve matter far more than straight-line speed — run slightly stiffer front ARB than default to sharpen turn-in for the S-complex, since any mid-corner push there costs more time than it would in a high-downforce GT3 car.

TRACK GUIDE

• Motodrom (T1): brake later than feels natural but in a straight line — GR86 has modest brakes, so get 90% of braking done before turn-in to avoid ABS-less lockup.
• Schumacher-S (T3): carry momentum, minimize steering corrections — the low grip/low power nature of the car rewards smooth rotation over aggressive trail-braking here.
• Dunlop hairpin (T5) & Bit-Kurve (T11): rotate the car early using light trail-brake, get back to full throttle as early as possible — the GR86 needs every bit of corner exit speed since it can't out-accelerate a loss of momentum.
• Veedol chicane (T13): sacrifice nothing on exit — this feeds the long back straight, and with low power, exit speed differences compound hugely by Shell.
• Ford-Kurve (T18) into stadium: late apex, prioritize traction on exit over entry speed — final sector lap time is won on getting straight-line drive through the stadium section.
