Briché and Navarro sign up for second JSB Competition Porsche

JSB Competition has revealed its second of three Porsche entries for this year’s GT4 European Series Powered by RAFA Racing Club, with team regulars Julien Briché and Jean-Laurent Navarro set to team up again.

Having run Aston Martins across recent years, French team JSB has invested in a trio of new Porsche 718 Cayman RS CS GT4s for the coming campaign, and has already confirmed Viny Beltramelli and Florian Briché as its first entry into the Silver class.

That duo will now be joined by long-time JSB driver Julien Briché and Navarro aboard a Pro-Am class car, with the third entry set to be revealed soon.

Julien Briché has a long history of racing both GT and touring cars, and a CV that includes titles in the Peugeot 206 CC Cup, the French SEAT Leon Supercopa, The Peugeot 308 Racing Cup and a Le Mans 24 Hours start. Briché switched to GT4 racing in 2021 and has raced regularly in both the French and European championships since.

Navarro also has a long background in touring car racing, the Frenchman having competed in single-make Renault and SEAT series before switching to the Lamborghini Super Trofeo. He moved into GT4 racing in 2020 and made his European championship debut in 2022 sharing a JSB-run Alpine A110 T4 with Briché. A race winner in the FFSA French GT Championship in each of the last two seasons, Navarro returns to the GT4 European Series for his second full season this year.
