2011 Radical SR3 RS

A true ‘world' supercar, the SR3 RS is as much at home flat-out through Eau Rouge, as it is providing passenger rides for your friends around the Nordschleife.
It is the world's most successful sports-racer, with over 600 satisfied customers. The SR3 RS is a sure-footed, highly-developed racer, adept and rapid in the hands of both the novice trackday driver, and seasoned racing professional.




First launched in 2002, the SR3 RS incorporates a six-speed sequential transmission, and drives via the Power Drive gear drive system, developed in partnership with Quaife especially for the SR3. With an integral torque-biasing differential, this reliable, easy-to-maintain unit is one of the SR3 RS's strengths, offering strong traction out of corners. Swapping gear ratios to suit specific tracks is a straightforward job.

Four-pot callipers, with vented discs on each corner, endear the SR3 RS with awesome stopping power.



An ergonomic and comfortable twin-seat cockpit makes the SR3 RS an ideal trackday car and endurance racer, with in-built engine datalogging, and an advanced LCD dash/multifunction display. Centre-locking wheels, and optional air jacks mean that, should the weather turn, the switch from slick to wet tyres is rapid and easy.
