DAMPERS

AERO

• Front Splitter: 2 (of typical 1–6 scale, low-drag biased)
• Rear Wing: 4 (of typical 1–8 scale, Spa needs low-drag for Kemmel/Blanchimont)
• Downforce level: Medium-low — prioritize top speed down Kemmel straight and through Blanchimont, accept slightly less front bite in Eau Rouge entry
• Brake Ducts: Front 2 / Rear 2 (cool but minimal drag penalty, tyre wear irrelevant this session)

KEY SETUP NOTE

• Spa GP rewards a low-drag aero setup far more than outright mechanical grip — the Kemmel Straight and flat-out Blanchimont sequence mean every click of rear wing costs time on the straights; run the minimum wing that still lets you commit flat through Eau Rouge-Raidillon without lifting.

TRACK GUIDE

• Eau Rouge/Raidillon: taken flat in quali trim if committed — stay full throttle, let the car track slightly left on the uphill crest, trust the aero load; any lift here costs massive time through Kemmel.
• Les Combes (T5): late, hard trail-braking entry — rotate the car on entry so you can get back to power early for the Kemmel straight run.
• Pouhon: a double-apex left that's flat-out capable in quali sim conditions with low fuel — carry speed, don't overslow the first apex, let the car drift out to the kerb on exit.
• Campus/Fagnes/Stavelot sequence: minimize steering input, flow the car through — any snap here ruins the run to Blanchimont.
• Bus Stop Chicane (final corner): this is the lap-defining corner — late braking, sacrifice the exit slightly to carry minimum speed loss, maximize traction onto the pit straight for your timed lap.
