In a market awash with 'BMW specialists', Birds are proud to stand apart.

We only offer the very best BMW performance tuning products to our customers, and only after conclusive testing on our own demonstrators. Our position as representatives for some of the world's premier BMW performance tuning brands generates its own credibility, but as a company firmly routed in performance engineering, our reputation goes way beyond the products we sell.

By only using the world's illustrious BMW performance tuning products, combined with our years of BMW performance tuning expertise (and some help from our partners!), we create some of the world's fastest BMWs for our customers. Our BMWs always receive top marks from the press, without fail.

We have been the official UK importer for Hartge, the renowned German BMW performance tuner, since 1986. We were selected by Dinan, the largest BMW performance tuning marque in the USA, to represent them in the UK. We are also the BMW master distributor for AP Racing, one of the world's leading brake system manufacturers.

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. In recent years we have 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.

The title ‘The U.K’s Premier BMW tuning Company’ was earned over more than 25 years through knowledge, hard work and honesty. We have always resisted the temptation to make short-term profit gains, as we believe that integrity and honesty has its own long-term rewards. You will find no internet “virtual tuning” or shopping carts at Birds, we are not interested in buying and selling parts. It is the genuine enthusiasm for real BMW performance tuning that has made us one of the U.K's most reputable BMW tuning companies. We pride ourselves on the products we offer, and we fully support all of our customers.

In 2007 we became the exclusive worldwide distributor for Quaife BMW limited slip differentials, a clever patented design using gears. Along with massive performance increases and seamless operation with BMW's electronics, we have seen this become our best ever selling product. The testimonials can speak for themselves, our customers believe it 'totally transforms' the car and 'is the best modification available for BMWs'.

We agree. We now have master Quaife BMW distributors and dealers in the U.S.A and all around Europe, in our expedition to make Quaife BMW the revolution in BMW performance tuning.

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'. Our new complete conversions and performance packages can be tailored to meet your requirements.
