DAMPERS

AERO

• Front splitter: 3 (of 5 clicks), Rear wing: 7 (of 10), Downforce: Medium-High, Brake ducts: Front 2 / Rear 3

KEY SETUP NOTE

• Spa's long straights (Kemmel, Bus Stop exit run) reward a rear wing setting that trades some Eau Rouge stability for straight-line speed — running slightly softer rear ARB with more mechanical grip (lower preload) helps rotate through Pouhon and Blanchimont without sacrificing top speed on the straights; tyre deg over race stints favors slightly higher rear pressure to prevent overheating under the sustained lateral loads through Eau Rouge-Raidillon and Pouhon.

TRACK GUIDE

• Eau Rouge-Raidillon: commit flat if the car is settled on entry; a lift here costs more than any other corner on track — trust the aero platform and stay smooth on the wheel, not the brakes.
• Les Combes (T5): late, aggressive trail-braking rewarded here — brake deep, rotate hard, get back to power early for the run to Malmedy.
• Pouhon: a high-speed double-apex left; treat it as one continuous radius, carry min speed through the middle rather than two separate inputs — this is where lap time is made or lost most.
• Bus Stop chicane: sacrifice ultimate mid-corner speed for a straight exit — traction onto the pit straight is worth more than the chicane entry speed given the long straight that follows.
• Fuel/tyre management: short-shift slightly out of Bus Stop and La Source during the mid-stint to save rears; push hardest in the final 2-3 laps of each stint once fuel load drops.

THEORETICAL BEST LAP

• 2:18.500 — optimal sector composite, dry, low fuel, soft tyres, based on GT3 pace reference

REAL WORLD RECORD

• No official record (GT3-spec cars vary by BOP/season; no single recognized "record" lap for this class at Spa)

SIM RACING RECORD

• 2:16.900 — iRacing GT3 class, Spa GP, dry conditions, community/league best estimate
