DAMPERS

AERO

• Front Splitter: 4 (of 6 clicks, medium-high)
• Rear Wing: 6 (of 10, Spa needs straight-line speed down Kemmel/Stavelot but stability through Eau Rouge/Pouhon is critical)
• Downforce Level: Medium-High — biased for Eau Rouge/Raidillon commitment and Blanchimont stability over outright Kemmel top speed

KEY SETUP NOTE

• Spa demands a setup confident enough through Eau Rouge-Raidillon flat-in-anger and Blanchimont at near-max speed, so ride heights and ARBs are kept slightly more conservative than a "pure qualifying" low-drag trim — losing a fraction on Kemmel straight is worth it for the confidence to carry full commitment through the two biggest corners on the lap.

TRACK GUIDE

• La Source: late, hard trail-brake entry, rotate the car tight to the inside kerb — exit traction here sets up the entire Kemmel straight run.
• Eau Rouge-Raidillon: full commitment flat in quali trim; keep the car settled on the left-right-left transition, don't lift or you lose the whole Kemmel straight.
• Les Combes: brake in a straight line after Kemmel, late apex the right-hander to carry speed into Malmedy's left-right flick.
• Pouhon: a lap-defining double-apex left — carry as much mid-corner speed as possible, trust the front end, this is where tenths are won.
• Blanchimont: taken essentially flat at high commitment — any hesitation here costs more than any other single corner on track.
• Bus Stop chicane: late braking into the final chicane, sacrifice a clean exit slightly if needed to protect lap time rather than risk a spin before the line.
