TYRES

Compound: Dry — Medium (standard GT3 slick)
Front Pressure: 27.2 PSI (cold)
Rear Pressure: 26.9 PSI (cold)
Tyre Blanket Temp: 80°C (standard ACC blanket setting)
Optimal Operating Window: 80–95°C for front and rear — peak grip at ~87°C; avoid exceeding 100°C to prevent thermal degradation over race stints.

Front Splitter: 5
Rear Wing: 6
Brake Ducts Front: 3
Brake Ducts Rear: 3
Downforce Level: Medium-high — biased for Paddock Hill stability and Clearways exit speed without sacrificing Druids traction.

Brands Hatch's blend of heavy braking (Paddock Hill), tight traction zones (Druids), and high-speed direction change (Clearways) demands a slightly stiffer front ARB than usual M4 GT3 baseline to control dive under late braking, while keeping rear diff power locking moderate (0.6) to avoid snap oversteer on Druids exit — critical for aggressive, late-braking driving style over race distance.

Paddock Hill Bend: brake late but straight-line; trail brake slightly into apex — downhill compression loads the front, so avoid over-slowing mid-corner.
Druids: sacrifice outright min-speed for a cleaner, earlier throttle application — traction out of Druids defines Cooper Straight speed and overtaking opportunity.
Graham Hill Bend: use trail braking to rotate the car early; aggressive drivers can carry more entry speed here than feels natural due to camber assistance.
McLaren Bend: committed single-apex approach — lift-and-reapply throttle smoothly to manage mid-corner lateral loads without upsetting rear tyre temps.
Clearways/Clark Curve: this corner makes the lap — carry max minimum speed on exit onto the front straight; a wide, late apex maximizes exit trajectory and straight-line speed for the following lap.
