Irmscher Automobilbau GmbH & Co. KG) is a German car tunes and manufacturing company specialising in Opel and recently Peugeot and Kia cars as well as working for the complete automotive industry as an engineering service provider.
It was founded in 1968 in a double garage in the Swabian town of Winnenden near Stuttgart (Germany) by rally driver and mechanic Günther Irmscher,.
Irmscher has retained close links to the Opel company by operating the factory team for Opel in many European and German automobile competitions, including the Ascona B i400 rally car, the Vectra touring car, the Astra DTM car and the Omega V8Star Series car.
This has led them to design and manufacture parts for Chevrolet, the Cadillac CTS and wheels for the GM based SAAB models, although these are much rarer than the Opel parts. Their distinctive customised parts include alloy wheels, bodykits and exhausts as well as various interior fittings.
