DAMPERS

AERO

• Front Splitter: 4 (of adjustable range), Rear Wing: 7, Downforce bias: slightly rear-biased for Skyline stability, Brake Ducts: Front 3 / Rear 4

KEY SETUP NOTE

• The single biggest factor is rear ride height and rear spring/ARB stiffness to keep the car planted over Skyline's crest at full speed — too soft and the rear goes light mid-crest at 260+ km/h, too stiff and you lose compliance for The Dipper's violent downhill compression immediately after; this setup splits the difference by running slightly taller rear ride height with moderate rear ARB to preserve mechanical grip through the transition.

TRACK GUIDE

• Hell Corner (T1): Brake hard but straight-line only — late apex slightly to maximize drive up Mountain Straight; this is a traction corner, not a rotation corner.
• The Cutting (T2/3): Attack the first kerb aggressively but be smooth on exit — unsettling the car here costs time all the way down the mountain.
• Skyline (T4): Commit flat-out; trust the rear aero/mechanical setup — any lift here loses more time than any other point on track.
• The Dipper to Forrest's Elbow: Brake in a straight line before Dipper, let the car settle on compression, then carry maximum committed speed through Forrest's — this is a rhythm section, not an attack point.
• Murray's Corner: This is THE most important traction zone on the lap — a clean, aggressive but controlled exit directly dictates your terminal speed down Conrod and your lap time.
• The Chase: Brake extremely late but in a straight line — trail brake slightly to rotate, then get back to power early; stability under brakes here is non-negotiable given the closing speed from Conrod.
