DAMPERS

AERO

• Front Splitter: 6
• Rear Wing: 7
• Brake Ducts: Front 4 / Rear 3
• (Rationale: stability bias for Eau Rouge/Blanchimont compression without killing Kemmel top speed too heavily)

KEY SETUP NOTE

• The Lexus RC F GT3 has a naturally stable but slightly nose-light platform at high speed — the rear ARB is kept soft (4) and rear wheel rate moderate to avoid snap oversteer on Raidillon's compression and Blanchimont's load transfer; the trade-off is slightly more mid-corner push at La Source, which is compensated by brake bias and aggressive trail-braking rotation rather than relying on a stiffer front end.

TRACK GUIDE

• La Source: brake extremely late but straight-line only, release brake pressure progressively to rotate the car on entry — trail-brake into the apex since the Lexus responds well to late rotation with this diff coast setting (0.4).
• Eau Rouge/Raidillon: full commitment flat in most GT3 setups with this aero level — keep the car dead straight on the compression, any steering input here will unsettle rear due to load transfer; earlier small lift costs less than a snap.
• Les Combes: this is where races are won — late braking into T5 with stable platform (fast bump 6 front) allows deep braking; use the inside kerb aggressively on exit of the chicane, car handles kerb strikes well with current damper rebound settings.
• Pouhon: carry min speed high, trust front splitter (6) for stable turn-in; aggressive drivers can carry 2-3 km/h more than conservative lines by trail-braking to the apex.
• Stavelot/Blanchimont: rear stability is the limiting factor for full commitment — the softer rear ARB and controlled fast rebound should allow near-flat Blanchimont if tyres are within temp window; manage rear tyre deg here over a stint since this is the highest-load corner for rear contact patch.
