Who We Are

Established in 1977 Ian Jemison Motorsport (IJEM) is a family owned specialist in motorsport engineering and repairs. Located in York with a wealth of experience in all aspects of motorsport engineering we support customers locally, nationally and internationally. From repairs and modifications to complete manufacture of hard to come by parts at IJE we really do provide a personal and complete service.

At IJEM, father and son Ian and Ben Jemison, who each drive their own cars competitively on numerous forest and tarmac rallies are equipped with credentials to deliver a superb service.

Ian started his rallying career in 1977 as a co-driver in the first Chevette that he built for the late ‘Piggy’ Thompson. He then went on to become a driver in his own very first rally car, a Ford Escort Mk2.  Always eager to build something different, Ian went on to build a mid-engined Vauxhall Nova fitted with one of the first 2.0 litre red top engines to be used in competition. The in 2003 Ian committed to building a Porche Boxster from a bare shell. The bodyshell required little alteration but was fitted with a comprehensive rollcage that Ian designed and fabricated himself. Ian’s Porche Boxster was first driven in 2005 and with the odd modification here and there since he continue to compete with the car today..

Ben was introduced to the family business as a willing young apprentice/rally driver (almost as soon as he could walk!) aged 14 years. Since his early days of throwing ta modified red mini around the North Yorks forests given to him by Ian and mother Alison Ben has gone on to become a first class engineer in his own right supportinmg Ian in the business, taking on almost complete responsibility for the allow wheel repair and refurbishment business and sin 2018 successfully completed the build of his ‘second’ rally car a Vauxhall Chevette in 2018
