DAMPERS

KEY SETUP NOTE

• With no differential and no aero to lean on, rear mechanical grip through Craner Curves and off Melbourne/Goddards comes purely from spring/damper balance — keep the rear slightly stiffer in rebound than the front to control weight transfer on throttle lift and prevent snap oversteer on the blind downhill entry at Craners.

TRACK GUIDE

• Melbourne Hairpin: brake hard but straight-line only — this car has no ABS, so trail-brake conservatively to avoid lockup, then get on power early for the long run to Craners.
• Craner Curves: commit fully, keep the car planted with smooth steering inputs — any mid-corner lift here with the open diff will unsettle the rear badly on the blind downhill left.
• Old Hairpin: late apex to maximize traction on exit for the long uphill climb — this is a major lap time zone given the car's low power.
• Coppice: treat as flat or near-flat — rear stability from damper tuning pays off here, carrying speed onto the back straight is crucial with only 140hp.
• Goddards: sacrifice outright min-speed for a clean, early throttle application — traction onto the pit straight matters more than corner speed in this underpowered car.
