Ferrari SF70H

TYRES

• Slick UltraSoft (US). Front 25.8 PSI cold / Rear 26.3 PSI cold — targets ~26.3–26.6 hot front, ~26.8–27.0 hot rear. Race fuel load (higher than the 133L reference lap's end-of-stint weight) adds slightly more working load through the rears, so rear pressure trimmed up slightly from the reference hot values to protect against overheating/graining across a stint. Optimal slick operating window: 90–100°C for peak grip. Blankets (if session allows) set at 80°C — expect the out-lap to still be below optimum, drive accordingly.

ELECTRONICS

• TC: 2 (medium-low, helps rear traction out of Bus Stop/La Source under aggressive power application without killing drive)
• ABS: 1 (minimal, this car rewards late braking feel — full ABS removes feedback on big stops like T1/Bus Stop)
• Engine braking / brake magic: Medium (helps rotation on entry to Les Combes and Bus Stop without snap oversteer)
• Brake Bias: 55.5% front (moved slightly rearward from the reference 56.0% — full fuel load race start needs less front bias to avoid front lock into T1/Bus Stop; trim forward by ~0.5% as fuel burns)

DAMPERS

AERO

• Front wing: 4 / Rear wing: 6 — medium-low downforce setup biased for Spa's long straights (Kemmel, main straight) while retaining enough rear stability for Eau Rouge/Raidillon flat-out commitment and the Pouhon/Stavelot high-speed corners. Brake ducts: Front 3 / Rear 2 — moderate cooling, race stint heat management without sacrificing peak braking performance into Les Combes and Bus Stop.

KEY SETUP NOTE

• Spa punishes low rear wing choices at Eau Rouge/Raidillon — with only 6 clicks rear wing you must commit flat-out through the uphill compression on a full tank; any hesitation or lift costs multiple tenths and risks a snap if the car isn't stable. Prioritize rear ride height and ARB stiffness slightly higher than a pure qualifying setup to keep the rear planted there under race fuel loads.

TRACK GUIDE

• Eau Rouge/Raidillon: full commitment flat in most conditions with this aero level — brake pressure and throttle must be smooth on entry at Eau Rouge, let the car run wide on exit at Raidillon naturally, don't fight it.
• Les Combes (T5): this is a heavy late-braking zone — trail brake deep into the right-hander, rotate on entry, sacrifice minimal speed for a strong exit toward Malmedy.
• Pouhon (T9-10): a long double-apex left — commit early on entry, use the full width, this corner rewards minimum lift and smooth rotation, it's a lap time differentiator.
• Bus Stop chicane (final corners): traction out of here onto the main straight is critical — get the rotation done early, prioritize a straight exit over outright mid-corner speed to maximize straight-line speed for the DRS zone.
• Fuel/tyre management: short-shift slightly out of Bus Stop and La Source in the opening stint laps to protect rear tyres; Spa's long lap and high-speed loading accelerates thermal deg in the rears more than fronts — manage REAR tyre temps especially through Blanchimont and Pouhon.
