DAMPERS

AERO

• Front Splitter: 2 (low-medium, minimise drag)
• Rear Wing: 5 (of typical 1–10 range — Monza-low but GT3 RS carries slightly more than peers for Lesmo/Ascari stability)
• Downforce Level: Low-Medium (Monza-spec)
• Brake Ducts F/R: 2 / 2 (minimal — single lap, no overheating concern)

KEY SETUP NOTE

• The 992 GT3 RS's high rear inertia and big fixed rear wing mean Monza wants the lowest drag trim you can stabilize — bias setup toward front rotation (soft front ARB, higher coast lock) rather than adding rear wing, since the car's natural rear downforce covers Parabolica; excess rear wing here only costs top speed on the two long straights without meaningfully improving your single-lap limit.

TRACK GUIDE

• T1/2 Rettifilo: brake as late as physically possible from 330+ km/h, trail into the first apex hard — the GT3 RS's front grip allows very late, aggressive trail-braking; use the exit kerb flat-out, car will rotate quickly due to low drag trim.
• Curva Grande (T3): taken essentially flat or lift-only — carry max speed, respect the rear on bumpy track-out, don't add steering input mid-kerb.
• Roggia Chicane (T4/5): second-heaviest braking zone — brake in a straight line, get all braking done before turn-in to avoid snap rotation from the pendulum rear mass.
• Lesmo 1/2: Lesmo 1 rewards late apex and front bite (trust the -3.7° front camber); Lesmo 2 is where understeer creeps in — be patient on throttle, let the car rotate before full power to set up the run to Ascari.
• Ascari chicane: this is where lap time is won — stay flat over the kerbs with the stiffer rear damping, minimize steering correction, and prioritize a straight exit over the inside kerb for max speed onto the back straight.
• Parabolica: the lap-defining corner — late, progressive throttle application exploiting the high power diff lock (0.35) and rear-engine traction; a clean, wide, accelerating exit here is worth more than any other single technique on track.
