Franck Montagny and Franck Perera will return to the Superleague Formula grid this weekend at Brands Hatch.
Former grand prix driver and two-time Le Mans runner-up Montagny skipped the last round at Zolder in Belgium, where he was replaced by Porsche Supercup racer Jaap van Lagen. But he will return to the seat this weekend, looking to build on the maiden victory he scored at Jarama last month.
Perera, a former GP2 podium finisher, will drive on the return of the French Olympique Lyonnais club - whose previous racer Sebastien Bourdais split from the team and series on the eve of Zolder.
The Lyon car will continue to be run by LRS Formula, and means the Superleague Formula field will return to its full complement of 18 cars.
Perera had previously raced in four rounds for Brazilian club Flamengo this year.
Meanwhile, Formula 2 champion and Virgin F1 reserve driver Andy Soucek retains his seat with Sporting Lisbon and will be hoping to build on his two top 10 finishes in Belgium.
