Ferrari F2004

TYRES

• Slick Soft (S). Cold pressures — Front 27.5 PSI / Rear 26.8 PSI. No tyre blankets (not supported in AC Evo) — expect a cold out-lap; build temp before pushing. Target hot pressures ~29.5–30.0 PSI front, ~29.0–29.5 PSI rear. Optimal operating window for Slick S: 85–105°C.

ELECTRONICS

• TC: 3 (low — Spa's traction zones at Eau Rouge exit and Bus Stop need minimal intervention for rotation, but full disable is too risky for a flying lap)
• ABS: N/A (banned — no ABS on this car)
• Engine Braking: Medium (setting 4 of typical 1–6 scale) — stabilizes rear into Les Combes and Bus Stop
• Brake Bias: 58.5% front (moved slightly forward from the logged 59.5% to compensate for cooler/stiffer dry conditions giving more front grip on turn-in at La Source and Bus Stop)

DAMPERS

AERO

• Front Wing Angle: 8 (of typical 0–10 scale — medium-low for Spa's long straights)
• Rear Wing Angle: 7 (balanced for Kemmel/Stavelot top speed vs. Eau Rouge/Pouhon downforce need)
• Ride Height front: 32 mm / rear: 45 mm (rake aids Eau Rouge stability and Blanchimont confidence)
• Brake Ducts: Front 2 / Rear 2 (medium — Spa is light on brake stress but long lap, keep discs in window)

KEY SETUP NOTE

• Spa demands a low-drag aero compromise for the Kemmel Straight/Stavelot run while still holding full commitment through Eau Rouge-Raidillon flat — run the rear wing low enough for straight-line speed but keep rear ride height/rake to protect floor-generated downforce through the uphill compression at Eau Rouge, where any bottoming or instability costs the entire lap.

TRACK GUIDE

• La Source (T1): Late, trail-braked entry from Kemmel straight speed — rotate the car tight to the inner apex, prioritize exit traction for the long run down to Eau Rouge.
• Eau Rouge-Raidillon: Taken flat in this car with full tank of aero grip — commit early, keep the car straight through the compression, any lift here costs more than a full sector.
• Les Combes (T5-6): Heavy braking after Kemmel straight — brake late but straight-line, second-gear right-left, don't carry too much entry speed or you'll run wide on exit.
• Pouhon (T9-10): Long double-apex left, taken at high speed — commit on the first apex, trust the aero, smooth steering input through to keep rear planted.
• Bus Stop Chicane (T19): Final key traction zone onto the pit straight — late braking, sacrifice some mid-corner speed for a clean, straight exit to maximize straight-line speed to the line.

TYRES

• Slick Soft (S) — Front: 20.5 PSI cold (target hot ~29.5 PSI) / Rear: 18.8 PSI cold (target hot ~29.0 PSI)
• No tyre blankets (not supported in AC Evo) — expect cold tyres on out-lap, build temp before timed lap. Optimal operating window for Slick S: 85–105°C.

ELECTRONICS

• TC: 3 (low — Spa's traction zones at Eau Rouge exit and Bus Stop chicane exit need slight slip control without killing drive)
• ABS: N/A — not fitted (banned in period F1)
• Engine Braking: Medium (standard map, aids rotation into La Source and Bus Stop without upsetting rear under trail-braking)
• Brake Bias: 58.8% front (moved slightly forward from the 59.5% recorded lap — Spa's heavy single-apex stops at La Source and Les Combes reward more front bite, but full 59.5 risks rear instability on the Eau Rouge compression and Pouhon's long rears-loaded turn; dry grip and cooler track favour a touch less front lock risk)

DAMPERS

AERO

• Front Wing Angle: 8 (medium-low — Spa demands straightline speed on Kemmel and the run to Les Combes)
• Rear Wing Angle: 7
• Ride Height front (mm): 32 / rear (mm): 45
• Brake Ducts: Front 2 / Rear 3 (long straights cool well, but heavy stops at La Source and Bus Stop need rear duct margin)

KEY SETUP NOTE

• Spa's lap is a compromise between Eau Rouge/Kemmel's need for low drag and stability at 300+ km/h, and the technical sector 2 (Pouhon, Campus, Fagnes) which rewards mechanical grip and front-end bite — run the lowest wing level that still keeps the car planted through Eau Rouge flat-out, since any lift there costs more time than the twisty middle sector gains.

TRACK GUIDE

• La Source (T1): heavy, low-speed hairpin after full-throttle run from pits — brake very late but in a straight line, rotate on entry to maximize exit traction onto the Kemmel Straight.
• Eau Rouge-Raidillon: taken flat in the F2004 with this aero — commit fully, stay central, let the car compress through the uphill blind crest; any lift costs massive terminal speed on Kemmel.
• Les Combes (T5-6): heavy braking zone after Kemmel — brake in a straight line, rotate hard on entry for the double-apex, exit wide to set up Malmedy.
• Pouhon (T10): fast, long double-left — carry min speed through the first apex, progressively build throttle, this corner rewards a stable rear and strong front-end grip from the setup.
• Bus Stop Chicane (T19): final chance to gain time before the long pit straight — late braking, sharp direction change, clean traction on exit is critical for straight-line speed to the line.
