Mercedes AMG tuning in Signes and around Le Castelet
Bernis Factory is located at 26 Allée de Dublin in Signes, in the Var. This address, 700 metres from the Paul Ricard circuit, shapes our work around high-end sports cars. Mercedes AMG owners from the region and visitors passing through Le Castelet find here a workshop dedicated to preparation, maintenance and restoration.
Preparing a Mercedes AMG means first understanding how it is used. A car driven mainly on the road does not call for the same settings as one meant to string together track sessions. That is why every preparation we carry out starts from your vehicle and your expectations, rather than a recipe applied to every Mercedes AMG.
Why entrust your Mercedes AMG tuning to a specialist workshop
Mercedes AMG tuning is not just about chasing a few extra horsepower. At Bernis Factory, it is part of a global approach that ties together the engine, the chassis and the braking, so the car stays coherent and enjoyable to drive. Our engine engineer maps each engine individually, which lets us adapt the character of the Mercedes AMG to its owner without applying a generic setting that would ignore the car in front of him.
This bespoke logic extends naturally to the track. Our workshop is 700 metres from the Paul Ricard circuit at Le Castelet, and we are an official BMW M France partner for track support, on top of being recommended by ORECA. Preparing a Mercedes AMG for track day use, checking the car before a session or stepping in on the day is part of our daily workshop life, alongside the maintenance and restoration of high-end sports cars.
