The workshop
Sullivan Bernis,
a new school
Founder of Bernis Factory, Sullivan opened the workshop in Signes in 2024, 700 m from the Paul Ricard circuit. He works there with an apprentice and a freelance engine engineer who comes in for bespoke ECU mapping.
No off-the-shelf maps pulled out of a piece of software here: every build is designed around how the car is actually used — daily, track day, or both. Real mechanical work, for enthusiasts who hand over their car like a child.

Client reviews
What they
say.
Bernis Factory's best salespeople are its clients — word of mouth, recommendations from the paddock, ORECA referrals.
Spotless work, meticulous down to the last detail. You can see he loves what he does — he prepped my 488 like it was his own.
You leave your car with him and you come back understanding it better than before. Pleasant surprise every visit.
When he says it's ready for the track, it's ready. Real mechanic work, not just plugging in an OBD scanner.
