British Touring Car squad Special Tuning Racing is planning to expand into the World Touring Car Championship next season.
STR scored a single BTCC victory in 2011 with Tom Boardman, who went on to finish 11th in the standings. Now the team plans to run two 1.6-litre SEAT Leons in the WTCC, as well as two two-litre machines in the BTCC.
Team principal John Boardman and technical director Gary Robertshaw visited the Macau WTCC finale last weekend and plan to run with SEAT Sport works customer support.
John Boardman said: "We are very excited by the prospect of working closely with SEAT Sport as a customer 'works' team. This will take our involvement with running SEAT touring cars to the next level.
"We have over eight years of experience racing the Leon in the WTCC, BTCC and SEAT single-make series and look forward to making our experience produce frontrunning pace in the WTCC."
No drivers have yet been confirmed, but Robertshaw said: "We are currently looking at a number of options. We feel that with our own technical expertise, and that of SEAT Sport, we can provide the attention to detail to run at the front in the WTCC."
