An influx of racers from the German Formula 3 Cup will boost next month's British F3 Championship round at Spa.
Motopark will take three cars to the Spa 24 Hours-supporting triple-header, while Dutch team Van Amersfoort Racing is hoping to field two.
Motopark boss Timo Rumpfkeil confirmed to AUTOSPORT that his squad will run Dallara-Volkswagens for Dutchman Indy Dontje, Malaysian Nabil Jeffri and Colombian Andres Mendez, who are third, fourth and seventh respectively in the German rankings.
He added that the team has the capacity to bring its fourth car, but no decision has been taken yet.
That car is usually raced by championship leader Markus Pommer, but it is unclear whether the Spa entry would be for the German or another driver.
Van Amersfoort chief Frits van Amersfoort said that he is working on taking Briton Sam MacLeod and Malaysian Weiron Tan - second and sixth respectively in the German F3 points - and that both drivers have shown an interest in the event.
MacLeod could also contest the Spa meeting with Fortec Motorsport, with which he won two races in the British F3 opener at Rockingham and has been linked with further BF3 outings.
