BMW M3 GT2

TYRES

• Slick, front 26.5 PSI cold (target ~28 PSI hot), rear 27.0 PSI cold (target ~28.5 PSI hot). Blankets set to 80°C if session allows; expect first-lap tyre to be below optimum through Esses — respect that on the out-lap.

ELECTRONICS

• TC: 2 (minimum usable for hairpin/chicane traction without killing rotation)
• ABS: 1 (low intervention, maximum threshold braking control for 130R/Degner entries)
• Engine Braking / Brake Migration: mid-low (3/6) to keep rear stable turning into Degner and Spoon
• Brake Bias: 56.5% front (base), rider adjusts -0.5% toward rear for Esses confidence

DAMPERS

AERO

• Front splitter: 4 (of typical 0-6 range) — enough front bite without stalling under 130R
• Rear wing: 6 (of typical 0-10) — prioritizes 130R/Esses stability over straight-line speed on the long back straight
• Brake ducts: front 2 / rear 3 — single lap, cooling less critical than aero stability

KEY SETUP NOTE

• The BMW M3 GT2 has significant aero-sensitive rear grip — running rear wing lower for straight-line speed will cost far more time through 130R and the Esses than it gains on the straight; this setup is deliberately biased toward high-speed rear planting at the expense of a few km/h on the back straight.

TRACK GUIDE

• T3-T7 Esses: commit early, smooth minimal steering corrections — any lift unsettles the rear through the direction changes; carry as much mid-corner speed as the rear will give, trust the wing.
• T12/13 Degner: brake in a straight line before turn-in, the entry is partly blind — don't trail-brake into the second part, it snaps the rear on cold/worn tyres.
• T14 Hairpin: this is the key lap-time corner — sacrifice entry speed for a clean, early throttle application; the following straight is long and rewards traction over rotation.
• T17/18 130R: full commitment flat or near-flat if the car feels planted from this setup — any hint of instability here costs the entire run to the chicane; brake extremely late for the final chicane, sacrificing chicane entry speed protects 130R minimum speed.
• Qualifying lap strategy: build tyre temp gradually in Sector 1, push hardest from the Esses onward once tyres are in window — the lap is won in 130R commitment, not outright braking points.
