Ferrari SF70H

TYRES

• Compound: Slick UltraSoft (US)
• Front: 25.3 PSI cold (settles ~26.0–26.3 hot)
• Rear: 25.9 PSI cold (settles ~26.5–26.8 hot)
• Optimal operating window: 90–100°C for peak grip (UltraSoft).
• No blankets assumed — build temp over out-lap, push hard through esses before flying lap to get fronts into window.

ELECTRONICS

• TC: 1 (minimal, Eau Rouge/Blanchimont stability over traction)
• ABS: 1
• Engine Braking: Medium
• Brake Bias: 54.5% front (moved slightly rearward from the 56.0% reference — cooler/lower track temp than logged lap means more front grip available, so bias pulled back to prevent front lock under the long, heavy braking zones at T1/Bus Stop and to rotate better into Les Combes)

DAMPERS

AERO

• Front Wing: 4
• Rear Wing: 6
• Downforce Level: Medium-low (Spa is a low-drag priority track — straight-line speed on Kemmel and the Bus Stop run matters more than peak cornering load)
• Brake Ducts F/R: 2 / 2

KEY SETUP NOTE

• Spa rewards a low-drag, stable-rear setup — the SF70H's long straights (Kemmel, main straight) punish excess rear wing far more than cornering grip gains repay; run the minimum rear wing you can hold through Pouhon and Blanchimont without the rear stepping out on throttle application.

TRACK GUIDE

• Eau Rouge/Raidillon flat in quali trim — commit early, let the car track out naturally over the crest, any lift costs the whole Kemmel straight.
• T1 (La Source): late, hard brake from ~320 km/h — trail brake deep to rotate the tight hairpin, prioritize exit traction for the Eau Rouge run.
• Pouhon (T9-10): a long double-apex left taken near-flat — commit to the first apex on a steady throttle, let the car drift wide between the two apexes, this corner defines lap time more than any other.
• Bus Stop chicane: brake late, sacrifice some mid-chicane speed for a straight exit onto the pit straight — exit speed matters more than entry here.
• Blanchimont: flat or near-flat at max attack — any lift here costs significant time and destabilizes the run into the Bus Stop.

TYRES

• Compound: Slick Ultrasoft (US)
• Front: 25.8 PSI cold (targets ~26.0–26.3 PSI hot)
• Rear: 26.3 PSI cold (targets ~26.6–26.9 PSI hot)
• No tyre blankets assumed — first lap must build temp progressively through Sector 1 (Eau Rouge/Raidillon load builds heat fast). Optimal slick operating window: 90–105°C, peak grip ~95–100°C.

ELECTRONICS

• TC: 1 (minimal, car has strong traction already from PU torque delivery — Spa's long straights reward low intervention)
• ABS: 1
• Engine Braking: Medium (3/5) — stabilizes rear into Les Combes and Bus Stop under trail-brake
• Brake Bias: 56.5% front (shifted slightly forward from the 56.0% reference lap to cope with cooler/stiffer track temp and heavier front loading into T1/Bus Stop chicane under max-attack late braking)

SUSPENSION

DAMPERS

AERO

• Front Wing: 3 (low-medium, prioritizes top speed down Kemmel and the Masta/back straights)
• Rear Wing: 4 (lowest usable level — Spa is the lowest-downforce circuit on the calendar; balance against Eau Rouge/Pouhon stability)
• Brake Ducts: Front 2 / Rear 2 (cool running lap, no deg concern, keep minimal drag)

KEY SETUP NOTE

• Spa's lap time lives in minimum front and rear wing you can carry flat-out through Eau Rouge-Raidillon and Pouhon without lifting — the SF70H's strong front end lets you run less rear wing than instinct suggests; the limiter is rear stability on Raidillon's crest, not outright downforce.

TRACK GUIDE

• La Source (T1): Brake very late, rotate hard on entry — it's the slowest corner on track, don't carry speed in, prioritize the exit onto Eau Rouge approach.
• Eau Rouge-Raidillon: Full throttle commitment flat in quali trim — stay central, let the car track the compression, any lift here costs 3-4 tenths down Kemmel.
• Pouhon: Double-apex left — carry minimum speed, trust the front end, this is where low-drag aero setup pays off most (high-speed stability test).
• Les Combes / Bus Stop Chicane: Late, aggressive trail-brake into Les Combes; at Bus Stop sacrifice outright entry speed for a clean, early throttle exit onto the pit straight — last big traction zone before the line.
• Overall: lap time is won on minimum lift through the Eau Rouge-Pouhon-Fagnes sequence — low-drag setup + confidence carrying speed through full-throttle/near-full-throttle corners outweighs mechanical grip gains elsewhere.
