Tuning that istruly bespoke
Every car that enters the workshop is handled individually: we start from how you really use it, on road and on track, before adjusting a single setting.

Bespoke first
We never load a generic map. Our engine engineer tunes the engine and gearbox case by case, based on your car and the way you actually use it.

Engine and gearboxbespoke mapping
Our maps never come from a catalogue. Each table is adjusted by an engine engineer for your car's engine and gearbox, road or track.

At the heart ofthe track world
An official BMW M France partner for track support and recommended by ORECA, the workshop also steps in trackside with its recovery truck.
A workshop within reach of Aix-en-Provence
Bernis Factory is located at 26 Allée de Dublin in Signes, in the Var. The workshop is easily reached from Aix-en-Provence and welcomes sports car owners looking for tuning genuinely suited to their vehicle rather than a standardised service.
On site, three trades complement one another: maintenance of high-end sports cars, preparation of engine, chassis, braking and gearbox, and restoration of youngtimers and classic cars. Washing, detailing and cosmetic bodywork are entrusted to trusted partners.
The immediate closeness of the Paul Ricard circuit shapes our business: we support enthusiasts from Aix-en-Provence and the region before, during and after their track sessions, right through to trackside assistance.

Car tuning in Aix-en-Provence and across the Var
Looking for a car tuning workshop near Aix-en-Provence often leads to providers who apply generic settings. Bernis Factory follows a different logic: each engine and gearbox is tuned individually by an engine engineer, based on how you really use your car, on road and on track. This bespoke approach applies equally to an AMG saloon, a Ferrari, a Nissan GT-R, a Porsche or a BMW M.
Based in Signes, 700 metres from the Paul Ricard circuit, the workshop brings together maintenance, tuning and restoration of high-end sports cars. An official BMW M France partner for track support and recommended by ORECA, Bernis Factory puts this experience at the service of enthusiasts from Aix-en-Provence and the whole Var. To study your tuning project, the simplest step is to talk directly with the workshop about your car and your goals.
