DAMPERS

AERO

• Front Splitter: 7, Rear Wing: 6, Brake Ducts Front: 2, Brake Ducts Rear: 3 — balanced for Kemmel top speed while keeping Eau Rouge/Raidillon and Blanchimont planted.

KEY SETUP NOTE

• The AMG GT3's long wheelbase gives stability but resists rotation — running slightly softer rear ARB (4) with quicker front response (higher front ARB 6, stiffer front wheel rate) plus a low coast lock (0.35) lets you rotate hard into La Source and Les Combes without inducing snap oversteer over the Eau Rouge compression or Blanchimont's high-speed load.

TRACK GUIDE

• La Source: brake late but in a straight line, trail brake to rotate the long wheelbase; get on power early for Kemmel run — this is the biggest lap time opportunity.
• Eau Rouge/Raidillon: flat in quali trim if platform is stable; stay full commitment, let the car settle on the compression, avoid lifting mid-corner — setup must not snap here.
• Les Combes: heavy braking after Kemmel — brake in a straight line, late apex the right-hander to set up the left, sacrifice min speed for exit traction onto the next straight.
• Pouhon: carry as much min speed as possible on entry, trust front grip, unwind steering progressively — time gained through committed double-apex.
• Blanchimont/Bus Stop: Blanchimont near-flat — stay smooth, don't lift; use full width and aggressive kerb riding at Bus Stop but keep car straight on exit for the line to the flag.
