Porsche 911 GT3 Cup (992)

• Note: The Porsche 911 GT3 Cup (992) is a fixed-spec one-make car — most cars in this class run limited setup adjustability (no ARB/damper range like GT3), but I'll provide the full range within the Cup car's actual adjustable window based on real-world 992 Cup regulations, adapted to AC Evo's parameter scales.

TYRES

• Slick (Michelin-spec Cup compound), Front 26.5 PSI, Rear 25.5 PSI, no tyre blankets — optimal operating window 85–95°C for peak grip, single-lap attack favors running toward 90–95°C surface temp achieved via out-lap tyre management.

ELECTRONICS

• TC: 3 (fixed-map Cup ECU, minimal intervention for max rotation on corner exit)
• ABS: 5 (aggressive late braking into Melbourne and Goddards needs stability)
• Engine Braking/Brake Migic: Standard (fixed, non-adjustable on Cup car)
• Brake Bias: 68% front (see below)

SUSPENSION

• // FRONT
• Ride Height: 55 mm
• Wheel Rate FL / FR: 130000 N/m / 130000 N/m
• ARB: 6 (fixed Cup scale, hardest for turn-in bite)
• Brake Torque Multiplier: 100%
• Brake Bias: 68%
• // REAR
• Ride Height: 60 mm
• Wheel Rate RL / RR: 110000 N/m / 110000 N/m
• ARB: 4 (softer to reduce snap on Coppice/Goddards exit)
• Diff Preload: 60 Nm
• Diff Coast: 0.7
• Diff Power: 0.5

DAMPERS

AERO

• Fixed Cup-spec rear wing (no adjustable front splitter) — rear wing angle set to max stall-resistant position (Position 4 of 5), no brake duct adjustability on 992 Cup, minimal front duct opening for brake cooling given single-lap heat cycle irrelevance.

KEY SETUP NOTE

• The GT3 Cup's fixed diff and rear-heavy weight bias means all your lap time is found in min-speed carry through Coppice and Goddards — over-slowing the rear on entry kills the exit onto the pit straight, so bias setup toward stability (softer rear ARB, higher coast lock) rather than outright rotation.

TRACK GUIDE

• Melbourne (T1): Late, straight-line braking from 265 km/h — trail brake lightly to rotate the rear-engined car into the apex, avoid trailing too long or you'll snap the rear.
• Old Hairpin (T4): Second-gear traction zone — get the car pointed early, sacrifice ultimate entry speed for a clean, full-throttle exit since this feeds the run to Coppice.
• Coppice (T6): Flat-out or near-flat commitment corner — this is the lap-defining corner; minimum speed here dictates your entire back-straight speed, carry as much mid-corner speed as the rear will allow.
• Macleans (T7): Quick direction change requiring sharp front-end response — aggressive steering input rewarded here due to Cup
