Johns passion for cars from modern to classic spans over 40 years. John started as an aircraft technician in the RAF working on phantom jets and helicopters for 10 years, in addition to preparing and maintaining cars for the RAF rally team.

Later John began building and supporting Alfa 156 to be raced in the Alfa Romeo and Auto Italia championship with an arrive and drive experience; moving next to the BTCC building and running two Alfa 147's for Tim Harvey, David Pinkney and Tom Ferrier, the highlight of the season being third at Oulton Park. I was involved in building the first ever 147 Super 1600 Rally Car for Steve Hill Motorsport, which we ran in the British Rally Championship. After all this involvement in Motorsport it inspired John to start his own business.

JJ performance was founded in 2003 by John and Jan Shields. The business has grown from strength to strength over the years as we pride ourselves on our friendly & professional service which is supported by our loyal customer base.
