For 1977, Boy Hayje drove a RAM-entered March with little success, and a second "rent-a-car" did no better later in the year when driven by Andy Sutcliffe, Mikko Kozarowitzky or Michael Bleekemolen. However, they had some success running Guy Edwards in the Shellsport Group 8 Championship in Britain, finishing 2nd overall. For 1978 the team switched to the British Aurora Formula One series, with Edwards placing 4th overall that year in a March, and 5th overall the following season in a Fittipaldi F5A. For 1980, RAM made an investment in a pair of 1979-spec Williams FW07s, with Emilio de Villota winning the title. Sponsorship included American men's magazine "Penthouse". They then entered one of these cars for Rupert Keegan in the British Grand Prix. Kevin Cogan and Geoff Lees would guest in another car in the last two rounds, but their best finish was Keegan's 9th place at the United States Grand Prix.
