Chevrolet Corvette Z06 GT3.R

TYRES

• Slick compound, front 27.2 PSI, rear 27.0 PSI (cold set targets, accounting for low fuel qualifying run), blankets not used in iRacing

ELECTRONICS

• TC: 2 (reduced from reference for max attack, low fuel, single lap)
• ABS: 3
• Brake magic/engine braking: Medium (standard GT3.R map)
• Brake Bias: 56.0% front (carried from reference lap, well suited to Spa's heavy stops)

DAMPERS

AERO

• Front splitter: max attack setting (+2 from baseline), Rear wing: 7 (of typical 1-10 GT3 scale), overall downforce level high — Spa requires strong rear stability for Eau Rouge/Blanchimont but low drag down Kemmel preferred trade-off slightly toward less rear wing (6) if straightline speed prioritized for qualifying tow; default to 7 without tow

KEY SETUP NOTE

• Spa demands a rare compromise: low-drag for the 2km Kemmel straight and flat-out Blanchimont, yet enough front end bite for Eau Rouge's blind compression and Les Combes' heavy brake zone — run slightly stiffer front ARB and lower front ride height than a "balanced" track setup to sharpen turn-in without sacrificing too much straight-line stability.

TRACK GUIDE

• Eau Rouge/Raidillon: taken flat in quali trim if committed — stay full throttle, let the car track slightly left then right through the compression; any lift costs 3+ tenths and compromises Kemmel exit speed.
• Les Combes (T5): heavy late braking from 300+ km/h, brake in a straight line, rotate on entry, sacrifice exit for a cleaner line into Malmedy.
• Pouhon (T9/10): twin-apex left, carry massive min speed — trust the aero, brake lighter than feels natural, let the car rotate mid-corner rather than on entry.
• Campus/Stavelot (T14-16): fast flowing esses, smooth inputs essential — inconsistent inputs here cost more time than anywhere else on track.
• Bus Stop chicane (final corners): late apex the first part, sacrifice a bit of entry speed to maximize exit traction onto the pit straight — this is the final lap-time opportunity.
