Belgian racer Pierre-Yves Corthals and Finn Antti Buri will join the field for the TCR International Series racers in Belgium, racing a SEAT León TCR and Volkswagen Golf GTi respectively.
Corthals is an experienced touring car racer who previously competed in the World Touring Car Championship between 2006 and 2010, taking part in 57 races and scoring two top ten finishes.
The 40-year-old Belgian has also been crowned champion six times in national and international Renault trophies, been victorious in Super Production championships and also participated in the European Touring Car Championship which pre-dated the WTCC.
Corthals will compete at the wheel of a SEAT entered by Netherlands-based team Ferry Monster Autosport, which will also run a car for Dutchman Loris Hezeman.
Buri, meanwhile, will race a VW Golf for Belgian outfit WRT, who are also supporting the new Leopard Racing outfit.
The Finn has also been competing in the ADAC TCR Germany series with an LMS Racing SEAT León, taking victory last weekend at the Sachsenring in the fourth race of the year.
