A track day coming up at Le Castelet? Let's prepare your car before you hit the track.

Track preparation
Track day preparation is about far more than freeing up a few horsepower before heading onto the track. At Bernis Factory, every setting starts from your car and from how you intend to use it on circuit. Our engine engineer maps the engine and gearbox case by case, never applying a generic program that would ignore your sports car's specifics.
This logic extends to the whole vehicle. High-performance braking, chassis preparation and the sport exhaust line are considered together so the car stays balanced and reliable lap after lap. The goal is not raw performance alone, but a healthy, predictable sports car that is enjoyable to drive on the track as well as on the road.

Before a session, we go over every area that matters on track: engine, braking, chassis and exhaust. You leave with a car set up for your use, and the reassurance of a team based right next to Paul Ricard should you need it.
Bernis Factory is located at 26 Allée de Dublin in Signes, 700 metres from the Paul Ricard circuit. This closeness changes everything for track day preparation: we can check the car before the session, adjust the setup between two runs and step in quickly on the day. Enthusiasts from the region and visitors passing through Le Castelet find here a workshop able to follow their sports car from servicing to the track.
It is the set of adjustments and checks that make a sports car fit to drive safely on track. At Bernis Factory this covers the engine, braking, chassis and exhaust, according to the intended use.
We prepare high-end sports cars such as Ferrari, BMW M, Mercedes AMG, Porsche or Nissan GT-R, for both track and road use. Each preparation is studied around the specific vehicle.
No. Every preparation is bespoke and depends on the car and your track programme. The simplest step is to tell us about your project for a suitable estimate.
Yes. Our workshop is 700 metres from the circuit and we offer track support, equipped with a recovery truck. We are an official BMW M France partner for support.
A healthy, well set-up car is essential to enjoy a track day with confidence. We check the mechanical condition and adapt braking and chassis to the demands of the track.
Finding a workshop that genuinely prepares a sports car for the track, rather than relying on ready-made recipes, is rare. Track day preparation requires understanding how the car behaves under load, when hot and over several laps. Bernis Factory approaches this work from Signes, with the eye of an engine engineer used to mapping engine and gearbox rather than applying a standard setting.
700 metres from the Paul Ricard circuit, the workshop brings together its three trades in service of the track: servicing sports cars, preparing their engine, braking and chassis, and supporting them on the day. This closeness and these partnerships, including being an official BMW M France partner, make track day preparation a natural extension of our work at Le Castelet.
