Reigning Ginetta Junior Winter Series champion Seb Priaulx will be back for a second season in the championship this year with JHR Developments.
Priaulx produced a superb maiden car-racing campaign in 2016, adding the Winter Series crown to his vice-champion honours in the Rookie Cup.
The Guernseyman secured fourteen Rookie podiums across the main campaign, as well as a superb overall victory at Silverstone.
That success came as part of the JHR squad, with his return expanding their 2017 line-up to five cars – joining Adam Smalley, Harry Dyson, Jenson Dineen and Matt Luff.
Priaulx’s 2017 challenge will come in a Ginetta G40J adorned with a red and white livery for new headline sponsor, 1st Central car insurance.
“Having 1st Central support me as I head into 2017 and beyond is an amazing boost for my career,” said Priaulx.
“I know from my father how finding such sponsorship at a crucial time is important. We can now work on laying down a foundation for my career and being able to plan long term is amazing.”
Seb’s father, current WEC star Andy Priaulx, added: “I am a very proud racing father, so for Seb to have attracted such a high profile long term sponsor so early in his career is pretty amazing.
“We are all excited about his future and are already looking to him moving into Formula 4 and then heading to a career that hopefully will take him right to the top.”
