FRS was a small British constructor active in the mid-2010s that developed lightweight two-seat sports prototypes for track-day use and 750 Motor Club competition. Its initial model, the Arrow, was promoted jointly with the 750 Motor Club in 2014 as the basis for an affordable “Sports Specials” entrant; a revised Arrow 2 followed soon after. The cars were marketed as simple, low-drag designs aimed at club racing and testing days, with readily available components and an emphasis on easy setup. Contemporary descriptions mention 2.0-litre Ford Duratec power for the Arrow 2.
