Ginetta G4R

The Ginetta G4R was the independently sprung development of the Ginetta G4 sports racer, introduced in 1964. According to the Ginetta Owners Club, the racing driver Chris Meek, who was winning races in a G4 with its 1500 cc engine bored out to 1650 cc, told Ivor Walklett how much would be gained from independent rear suspension. Walklett, who was already working on an independent rear chassis for what became the G7, adapted that layout to the Ford engine and gearbox, with hub carriers driven by a cut down BMC axle that kept only the differential and inboard disc brakes. The first car used a Lotus Twin Cam engine and won on its unplanned debut at Mallory Park in July 1964 with Meek driving, and the model became formally available in September 1964. Cars raced at the Nurburgring and Montlhery, and the United States importer entered one in the 1965 Sebring 12 Hour. The Ginetta Owners Club of Switzerland lists it as a 1500 cc sports racer whose production is counted within the G4 total.
