DAMPERS

AERO

• Front Splitter: Level 3 (of 5)
• Rear Wing: Level 8 (of 10), the 992 likes more rear wing, needed for Westfield and Clearways stability
• Downforce Level: Medium-High (Brands is a medium-speed, rhythm-based circuit)
• Brake Ducts: Front 2 / Rear 1 (single lap, so minimal cooling demand; keeps brakes in the hot window)

KEY SETUP NOTE

• The 992's rear-engine pendulum is the limiting factor at Brands Hatch. Keep the rear ARB soft (38,000 N/m) and the rear ride height at 72 mm, because dropping it lower triggers snap oversteer on the Druids and Clearways exits. The compliant rear lets you carry power early, while the 57% front brake bias and low engine braking let you trail-brake the car into rotation at Paddock Hill and Graham Hill. Diff preload at 70 Nm steadies the rear on the hard kerb attack without killing rotation.

TRACK GUIDE

• Paddock Hill Bend (T1): Brake late at the crest and keep the car compressed into the downhill. Trail the brakes to the apex and run late and wide, since the front load is high here. Don't rush the throttle, because the exit sets up Druids.
• Druids (T3): Brake hard in a straight line, rotate with trail braking, and get the car pointed early. This is the main traction zone. Squeeze the power progressively to keep the 992's rear planted, as sector 1 is won on this exit onto Graham Hill.
• Graham Hill Bend (T4): Trail brake in for rotation and use the kerb on exit. A clean exit sets up the run to Surtees.
• Surtees to Hawthorn to Westfield (T8–T11): Stay committed over the Surtees crest and keep the rear planted, with minimal steering inputs. Take Westfield flat or nearly flat, trusting the rear wing.
• Dingle Dell / Sheene, Stirlings, Clark Curve (T12–T16): Attack the Sheene kerbs without upsetting ride height. Square off Stirlings for a clean exit, then carry maximum speed through Clearways, where exit speed defines the lap time down the main straight.

TYRES

• Compound: GT3 Slick (Medium) — race stint compound
• Front Pressure: 1.90 bar
• Rear Pressure: 1.85 bar (cold start; expect +0.15 to +0.20 bar build-up)

DAMPERS

AERO

• Front Wing: Not adjustable (splitter fixed)
• Rear Wing: Level 8 (high-downforce setting for Brands Hatch's medium-speed, rear-limited layout)
• Downforce Level: High
• Brake Ducts: Front 3 / Rear 2 (moderate cooling; the Paddock Hill and Druids stops are heavy but the lap is short and cool)

KEY SETUP NOTE

• The 992's rear-engine inertia makes it pendulum into Paddock Hill Bend and Druids if the rear is too soft or too low. Keeping rear ride height at 74 mm with the 0.7 coast diff stabilises the car under late, aggressive braking. Rear tyre wear is the stint limiter, so use the 0.4 power diff to avoid spinning the inside rear on Druids and Clearways exits.

TRACK GUIDE

• Paddock Hill Bend (T1): Brake late at the crest while the car is still straight, then ease off as the car compresses downhill. Trail the brake in to rotate, take a late apex, and keep the rear planted. Do not overslow the entry or you lose the whole Druids run.
• Druids (T3) / Graham Hill (T4): Brake hard in a straight line, rotate on the brake, and get the car pointed early. Squeeze the throttle progressively to protect the rear tyres on this tight exit. This is the main traction zone of sector 1.
• Surtees (T8) / Hawthorn (T10) / Westfield (T11): Stay smooth and keep the rear loaded through the fast sweeps. Westfield loads the rear tyres laterally, so commit but avoid sawing at the wheel, which overheats the rears over a long stint.
• Dingle Dell / Sheene (T12/13): Ride the kerbs aggressively, but the 74 mm rear ride height should prevent bottoming. Square the chicane and get a clean exit toward Stirlings.
• Clark Curve / Clearways (T16): Lap time is won or lost here. Sacrifice some entry speed to be on the throttle early, and track out fully onto the main straight. Every km/h carried onto the straight is worth tenths.
