DAMPERS

KEY SETUP NOTE

• With no diff and a live/solid rear setup reliant on mechanical grip alone, the rear ARB must stay soft relative to front to prevent inside-wheel lift under hard trail-braking into Druids and Graham Hill — prioritize rotation through softer rear roll stiffness and accept slightly more body roll in exchange for confident corner entry rotation, since this chassis has zero electronic aids to correct a snap.

TRACK GUIDE

• Paddock Hill Bend: brake late but progressively — this is a blind, downhill, off-camber entry; trail brake deep and trust the front end, car rotates naturally downhill.
• Druids: this is where lap time is made or lost — sacrifice min-speed for a clean, early throttle application; the short, light chassis will step out if power is applied before the car is pointed.
• Graham Hill Bend: trail brake into the left-hander, let the stiffer front/softer rear balance rotate the car on entry, get back to throttle progressively on the downhill exit.
• McLaren Bend: committed, high-mid-speed lateral load corner — carry momentum, minimal steering correction, let the aero-less low-mass chassis ride through on mechanical grip.
• Clearways/Clark Curve: exit speed here dictates straight-line speed onto pit straight — unwind steering early and get full throttle down before the final kerb to maximize terminal speed.
