The team participated in one Formula One World Championship Grand Prix but failed to qualify.

Brian McGuire first started to race in the British-based Shellsport G8 International Series in 1976, as a private entry with the Formula One-specification Williams FW04.

He also entered the car for the 1976 British Grand Prix but was only listed as a reserve and never made it on to the track.

However, the car was uncompetitive in the special pre-qualifying sessions, slower than all the other entrants except Mikko Kozarowitzky who had an accident, and McGuire failed to make it through to the full qualifying sessions.

[1] Brian McGuire was killed at the wheel of the car at Brands Hatch later in 1977.
