DAMPERS

KEY SETUP NOTE

• With no diff and only 140hp, the 270R relies entirely on low ride height and stiff-ish springs/ARBs to minimize pitch and roll through Snetterton's fast direct-change corners (Bombhole, Hamilton); running minimum legal ride height (52/58mm) while keeping front ARB slightly stiffer than rear sharpens turn-in without inducing inside-rear lift under power, critical since there's no diff to manage wheelspin on exit.

TRACK GUIDE

• Turn 1 (Riches): Brake late and straight-line, trail slightly to rotate — car is light enough to rotate aggressively without upsetting rear if ARB balance is correct.
• Bombhole/Coram sequence: Carry maximum minimum speed; this is a momentum car, so smoothness through the fast direct-change kink matters more than outright apex speed — lifting costs more time than in higher-powered cars.
• Russell/Agostini chicane: Late apex Russell to maximize exit speed onto the back straight — this is the biggest traction zone and with no diff, smooth throttle application is essential to avoid inside-wheel spin.
• Palmer corner (final corner): Entry speed is everything — compromise the exit slightly for a cleaner, straighter line onto the pit straight since this is the longest flat-out stretch.
• Overall: Lap time is won through momentum conservation — avoid scrubbing speed with excessive steering input; this car rewards patience in mid-corner and aggression only on initial turn-in and final exit throttle.
