Ferrari F2004

TYRES

• Compound: Slick Soft (S)
• Front: 20.0 PSI cold (targets ~29.5 PSI hot)
• Rear: 18.5 PSI cold (targets ~29.0 PSI hot)
• No tyre blankets in AC Evo — expect 2-3 corners of reduced grip on the out-lap before the tyre reaches the 85–105°C optimal window.

ELECTRONICS

• TC: 2 (minimal — Spa's traction zones at Eau Rouge exit and T19 Bus Stop need some slip control, but low TC preserves rotation)
• ABS: N/A — not fitted, 1994 regulation ban
• Engine Braking/Diff Map: Medium (see diff values below)
• Brake Bias: 59.5% front (shifted slightly rearward from the 60.0% reference lap to aid rotation into Les Combes and the Bus Stop chicane on a cold-ish track)

SUSPENSION

• // FRONT
• Ride Height: 30 mm
• Wheel Rate FL / FR: 95,000 / 95,000 N/m
• ARB: 85,000 N/m
• Brake Torque Multiplier: 100%
• Brake Bias: 59.5%
• // REAR
• Ride Height: 45 mm
• Wheel Rate RL / RR: 62,000 / 62,000 N/m
• ARB: 18,000 N/m
• Diff Preload: 55 Nm
• Diff Coast: 0.35
• Diff Power: 0.55

DAMPERS

AERO

• Front Wing Angle: 8
• Rear Wing Angle: 7
• Ride Height front (mm) / rear (mm): 30 / 45
• Downforce level: Medium-Low (Spa's long straights reward low drag; retain just enough to hold Eau Rouge/Blanchimont flat)
• Brake Ducts: Front 3 / Rear 3 (long straights give ample cooling — keep ducts closed to minimize drag)

KEY SETUP NOTE

• Spa demands the widest wing/ride-height compromise of the season — Eau Rouge-Raidillon and Pouhon need serious front-end confidence from ride height and camber, while Kemmel Straight and the Bus Stop-to-start/finish run punish any extra drag; this setup trims wing level to the minimum that still holds Eau Rouge flat-out, accepting slightly less stability in the Esses in exchange for straight-line speed.

TRACK GUIDE

• Eau Rouge-Raidillon flat in this car with this downforce level — commit on the left-hand kink, let the uphill compression settle the car before Raidillon's crest; lifting here costs more than anywhere else on track.
• Les Combes (T5): brake late and straight-line under full ABS-less threshold braking — trail off smoothly, this is a classic overbraking trap into a tightening right.
• Pouhon (T9-10): a high-speed double-apex left — commit to a wide entry, trust the aero, and let the car run to the exit kerb; this corner rewards earned confidence more than outright bravery.
• Campus/Stavelot sequence (T13-15): compressions and direction changes — keep the car settled, avoid snap inputs, as the F2004 at low ride height is sensitive to vertical load changes here.
• Bus Stop chicane (T19): the only true heavy-traction zone — sacrifice a tenth on entry for a clean, straight exit onto the pit straight; diff power lock and TC level 2 are tuned specifically for this exit.
