TYRES

  • Slick, F 27.0 PSI, R 26.6 PSI (cold/qualifying trim, one-lap heat build-up accounted for). Optimal operating window for max grip: 85–95°C (peak ~90°C). Blanket temp if used: 80°C.

ELECTRONICS

  • TC1: 3, TC2: 1, ABS: 5, Engine Braking: Medium (3/5), Brake Bias: 54.0% front (cockpit adjustable, start here)

AERO

  • Front wing: 2 (max attack low-drag trim for Spa's long straights), Rear wing: 4 (balanced for Eau Rouge/Blanchimont stability without killing top speed), Downforce level: Medium-Low, Brake ducts: F 2 / R 3

KEY SETUP NOTE

  • Spa demands a rare compromise — low drag for Kemmel Straight and the run to Les Combes, but enough rear stability to send Eau Rouge/Raidillon flat-out and hold Pouhon/Blanchimont without lifting; bias the wing setup toward straightline speed and let mechanical grip (softer rear ARB, slightly more rear ride height) carry the high-speed corners.

TRACK GUIDE

  • Eau Rouge/Raidillon: commit flat in quali trim — late apex at Eau Rouge, let the car drift to the right over the crest at Raidillon; lifting here costs more than any other corner on the lap.
  • Les Combes (T5): heavy braking zone after Kemmel Straight — brake late in a straight line, rotate the car on entry using trail-braking to set up the double-apex.
  • Pouhon (T10): flat-in-high-gear or lift-and-glide depending on aero — carry max minimum speed, this corner rewards commitment and good front-end platform from the stiffer front springs.
  • Campus/Stavelot/Blanchimont: Blanchimont should be taken flat with this aero package — any lift here is a lap time killer on the fast final sector.
  • Bus Stop Chicane: late, hard trail-brake entry, sacrifice some mid-corner smoothness for a strong exit onto the pit straight — traction out of here feeds directly into lap time.

TYRES

  • Slick (Dry) — Front: 27.8 PSI cold, Rear: 27.5 PSI cold
  • Optimal operating window: 85–100°C for peak grip; target 90°C average across stint. Endurance note: let pressures run slightly higher than qualifying setup to account for heat cycling over a race stint — starting 0.3–0.5 PSI above pure qualifying pressure prevents overheating in traffic/DRS trains.

ELECTRONICS

  • TC1: 5 (reduce to 4 as fuel load drops and tyres wear in final stint)
  • TC2: 2
  • ABS: 5
  • Engine Braking / Brake Magic: Medium (3/5)
  • Brake Bias: 54.5% front (base), adjustable 54–56% as pads/tyres evolve

AERO

  • Front Splitter: 4 (clicks, max stable downforce for Spa)
  • Rear Wing: 6 (of typical 1–8 range — balanced for Kemmel/Blanchimont straight-line speed vs esses stability)
  • Downforce Level: Medium-High (Spa configuration priority — straight-line efficiency through Kemmel & main straight, with enough load for Pouhon/Blanchimont)
  • Brake Ducts: Front 4 / Rear 3 (endurance thermal management)

KEY SETUP NOTE

  • Spa's long straights (Kemmel, main straight) reward low drag, but Pouhon and the Eau Rouge/Raidillon complex demand serious front-end confidence at high speed — this setup compromises toward slightly higher rear ARB stiffness and conservative front splitter to keep the 296's front-heavy nature planted through Eau Rouge without killing straight-line speed; manage tyre deg by easing TC-induced rear wear via diff power lock reduction in final stint.

TRACK GUIDE

  • Eau Rouge/Raidillon: committed full-throttle approach only with confidence — car must be stable on entry; any lift unsettles weight transfer violently uphill.
  • Les Combes (T5): late aggressive braking rewarded, but don't overslow — compromises exit onto the long back straight run to Pouhon.
  • Pouhon (T9-10): a lap-defining double-apex left — carry max minimum speed, trust front end, progressive throttle application through both apexes.
  • Bus Stop Chicane (final corners): sacrifice minimal speed, prioritize clean exit onto main straight — exit traction here is worth more than entry speed given Spa's long run to T1.
  • Fuel/tyre management: lift-and-coast slightly into Les Combes and Bus Stop during middle stint laps to preserve rear tyres without major lap time loss.
