Toyota GR86

TYRES

• Slick (dry), Front: 27.0 PSI, Rear: 27.5 PSI
• Optimal operating window: 80–95°C for peak grip (slicks). Target hot pressures ~29–30 PSI front/rear once up to temp. For a single flying lap in 20–21°C ambient/track, start cold pressures slightly lower to reach the window within 1–2 laps.

ELECTRONICS

• TC: 0 (max attack, single lap, no need to manage tyre life)
• ABS: 2
• Engine Braking/Brake Magic: N/A (fixed on GR86)
• Brake Bias: 50.5% front (very marginally forward from logged 50.0% to stabilize entry under max-attack late braking, given cooler track temp reduces rear grip slightly)

DAMPERS

AERO

• Fixed aero (GR86 stock aero, no adjustable wing). No brake duct adjustment available — leave stock.

KEY SETUP NOTE

• Snetterton's long Bentley Straight and high-speed Riches/Agostini sequence reward a stable rear platform — slightly stiffer rear ARB and increased power diff lock help put power down out of Russell and Palmer without inducing snap oversteer on corner exit, critical since TC is off for max attack.

TRACK GUIDE

• Turn 1 (Riches): carry big speed, trail brake late and trust front grip — this is where the lap is won or lost on entry commitment.
• Nelson (Turn 2-3 chicane): minimize steering input, use curbs aggressively on exit to maximize speed onto the Bentley Straight.
• Brake extremely late into Agostini (Turn 7) — straight-line braking stability is key with 50.5% front bias.
• Palmer (final corner): traction out is crucial — slightly earlier power application pays huge dividends onto the pit straight.
• Coldberry chicane (Turn 10-11): sacrifice minimum apex speed for a clean, straight exit — late apex here feeds the long run to the final corner.
