Birds - The U.K's Premier Tuning Company

As an independant and family-owned business since 1979, we offer the personal and honest service that you will struggle to find elsewhere. Our reputation of competence and ability to provide genuine solutions has absolutely been the key to our success.

We are one of the very few BMW performance tuning companies who can undertake all work 'in house'. BMW Dealers from 1974 until 1984, we subsequently made waves in the market with our hugely successful RHD conversions for the E30 M3 back in the 1980s. Our history includes having researched, developed and brought to market both the Switchlogic F1-style gearbox system, and an entirely new BMW tuning marque - Spirit - built around cutting edge supercharger technology.

We have been the official UK importer for Hartge, the renowned German BMW performance tuner, since 1986. We are the BMW distributor for AP Racing, and the sole distributor of Quaife limited slip differentials for BMWs worldwide. However our expertise and resources allow us to develop solutions when there are none available elsewhere, such as the popular B1 and B3 suspension kits.

Each and every driver has their own requirements, and consultation with our expert staff is the only way to learn how to truly improve the 'Ultimate Driving Machine'.
