What is bespoke chassis tuning?
Chassis tuning covers all the settings that define how a car behaves: its roadholding, its balance and the precision of its responses. At Bernis Factory, it never comes down to an off-the-shelf recipe. We start from your car, its real-world use and your expectations to define the work to carry out on the suspension and running gear, rather than applying a standard setup that would ignore the car in front of us.
This bespoke logic is the same one that guides our engine mapping: every sports car is treated individually. Whether you drive mostly on the road, aim for track days or look for a compromise between the two, the goal stays the same — to make the behaviour more coherent and more enjoyable, without diluting your car's character.
Our chassis tuning method in Signes
Our approach starts by understanding how you use your car. A chassis built for the road favours comfort and versatility, while a track-oriented setup looks for more precision and stability at high speed. We define this starting point together before any work begins, so that the result genuinely matches the way you drive.
Work on the chassis is carried out in line with the rest of the preparation: engine, gearbox and braking all move in the same direction. Our workshop brings together three trades — maintenance, preparation and restoration — which lets us treat your sports car as a whole rather than in isolation. You keep a single point of contact from the diagnosis through to the test drives.
Chassis tuning and the Paul Ricard circuit
Our workshop is located 700 metres from the Paul Ricard circuit at Le Castelet. This closeness changes a lot for chassis tuning: we can support owners before, during and after a track session, and check our settings against the reality of the track. As an official BMW M France partner for track support and recommended by ORECA, we also have a recovery truck to step in directly on site if needed.
Chassis tuning in Signes and around Le Castelet
Bernis Factory is based at 26 Allée de Dublin in Signes, in the Var. This location, a few minutes from the Paul Ricard circuit and Le Castelet, shapes our work around high-end sports cars: Ferrari, Mercedes AMG, Nissan GT-R, Porsche or BMW. Whether you are local or passing through to drive on the circuit, you will find a workshop able to handle your car's chassis tuning along with its other mechanical needs.

Chassis tuning is rarely considered on its own: it works alongside the engine, the braking and track support. Here are the pages that help you build a coherent project.
Frequently asked questions about chassis tuning
- What is chassis tuning at Bernis Factory?
- It is the set of adjustments that improve how your car behaves: roadholding, balance and precision. We approach it case by case, starting from your sports car and its use, without applying any generic setup.
- Is chassis tuning suitable for both road and track use?
- Yes. We define the desired direction with you, from road comfort to the sharpness sought on track, or a compromise between the two. Being close to the Paul Ricard circuit helps us validate the settings in real conditions.
- Do you work on the chassis alongside the engine and braking?
- Yes. Our workshop brings together maintenance, preparation and restoration, which lets us move the engine, gearbox, braking and chassis in the same direction, with a single point of contact.
- Which cars do you handle for chassis tuning?
- We work on the high-end sports cars we prepare every day, such as Ferrari, BMW M, Mercedes AMG, Porsche or Nissan GT-R, for both road and track use.
- Do you give a price for chassis tuning?
- No, because every preparation is bespoke and depends on your car and its intended use. The simplest step is to contact us so we can study your project and suggest a suitable course of action.
Chassis tuning designed for high-end sports cars
Finding a workshop that approaches chassis tuning with a genuinely bespoke logic is not that common. Many simply fit parts without considering how the owner drives. Bernis Factory instead starts from your car and the way you use it to define the work on the running gear, with the same care it brings to engine mapping.
Based in Signes, 700 metres from the Paul Ricard circuit, our workshop brings together the maintenance, preparation and restoration of high-end sports cars. Chassis tuning naturally fits in, in line with the engine and braking, for cars that are as pleasant on the road as they are effective on track. Tell us about your project and we will work out the next steps together.
