How we tune your BMW M

Testing and fine-tuning
We validate the preparation through testing and refine the settings until the desired behaviour.
BMW M tuning and the Paul Ricard circuit
- Official BMW M France partner for track support
- Workshop 700 metres from the Paul Ricard circuit, at Le Castelet
- Track support equipped with a recovery truck
- Workshop recommended by ORECA
Preparing a BMW M for the track means knowing the circuit. Our closeness to Paul Ricard lets us support your car before, during and after a track day.
BMW M tuning in Signes and around Le Castelet
Bernis Factory is located at 26 Allée de Dublin in Signes, in the Var. Our workshop tunes the BMW M cars of local enthusiasts as well as visitors passing through the Paul Ricard circuit. This closeness to the track shapes the way we work: every preparation takes into account how the car is actually used, on road and on track.
Beyond tuning, we handle the maintenance and restoration of high-end sports cars. A BMW M that passes through our hands receives the same care, whether it is engine mapping, work on the chassis and braking, or a complete track day preparation.
A workshop dedicated to bespoke BMW M tuning
Finding a workshop able to tune a BMW M without applying a ready-made map is not so simple. At Bernis Factory, every engine is tuned individually by an engine engineer, taking into account the model, its condition and the way you use it. This bespoke approach applies to engine mapping as well as to work on the chassis, braking and exhaust line, so that your BMW M gains coherence rather than raw figures.
Our Signes workshop brings together three trades around high-end sports cars: maintenance, preparation and restoration. For a BMW M, this means complete follow-up, from a simple service to track preparation, including support on the day of a track session at Paul Ricard. As an official BMW M France partner for track support and recommended by ORECA, we put this experience at the service of your car, without promising what we do not master.
