Aston Martin Vantage GT3 EVO

TYRES

• Slick (Dry), Front: 27.5 PSI cold, Rear: 26.5 PSI cold — target hot pressure 27.5–28.5 PSI all round. Optimal operating window: 85–105°C (peak grip ~90–95°C). Qualifying lap: bias setup slightly toward lower starting pressure since single-lap heat build won't fully cycle tyres — do not over-blanket.

ELECTRONICS

• TC: 2 (minimum for max attack, rear stability enough at Eau Rouge with mechanical grip)
• ABS: 5
• Engine Braking: Medium (4/6)
• Brake Bias: 54.5% front

SUSPENSION

• // FRONT
• Ride Height: 55 mm
• Wheel Rate FL / FR: 145000 N/m / 145000 N/m
• ARB: 120000 N/m
• Brake Torque Multiplier: 100%
• Brake Bias: 54.5%
• // REAR
• Ride Height: 60 mm
• Wheel Rate RL / RR: 130000 N/m / 130000 N/m

• Diff Preload: 40 Nm
• Diff Coast: 0.5
• Diff Power: 0.6

DAMPERS

AERO

• Front Splitter: 4 (max attack, accept drag for Pouhon/Les Combes front bite)
• Rear Wing: 8 (of 10) — prioritise Eau Rouge/Blanchimont stability over Kemmel top speed
• Downforce Level: High-Medium (balanced for Spa's mixed layout)
• Brake Ducts: Front 4 / Rear 3

KEY SETUP NOTE

• The Vantage EVO's rear can go light over the Eau Rouge compression and Blanchimont's off-camber load transfer — running slightly stiffer rear ARB and lower rear ride height than "standard" GT3 Spa setups sacrifices a fraction of Rivage traction but buys the confidence to keep full throttle through Raidillon, which is worth far more lap time than mid-corner traction anywhere else on track.

TRACK GUIDE

• La Source: brake as late as possible in a straight line, trail-brake to rotate — undertrim entry speed slightly to protect exit onto Kemmel, the longest acceleration zone on track.
• Eau Rouge/Raidillon: commit flat if track temp allows; if lifting, do it minimally on the uphill left before Raidillon crest — any snap here costs the entire Kemmel straight.
• Les Combes: brake in a straight line, very late, downshift aggressively — this is where TC=2 and strong ABS matter most to avoid front lock under heavy compression.
• Pouhon: carry min speed high through first apex, unwind smoothly — front-end grip from splitter setting pays off directly here.
• Blanchimont: near-flat is the target; small lift only if rear
