After three rounds of the championship, Romain Grosjean and Thomas Mutsch of Matech once again lead the Drivers Championship for the first time since their victory in Abu Dhabi to start the season. Grosjean and Mutsch lead the Vitaphone pair of Michael Bartels and Andrea Bertolini by twelve points. In the Teams Championship however it is Vitaphone who are on top but are carrying only a four-point margin over Matech. Also, following a fire at Silverstone, Phoenix is once again down to a single Corvette, reducing the series grid to 23. Defending GT1 class race winner Enrique Bernoldi, who won the 2009 FIA GT event in a Corvette, is also part of the 2010 field with Vitaphone Maserati.
Following the previous round in Brno, performance balancing modifications were published by the FIA which affected four manufacturers. The affected four, Corvette,[2]Maserati,[3]Ford,[4] and Aston Martin,[5] all had weight added to their minimum requirement in order to retard their performance potential, with Maserati having the most dramatic change with 55 kg (121 lb) added to their minimum.[3] Further, the Fords also had their air restrictors reduced in size in order to decrease engine power. In addition to performance balancing weight additions, four teams had success ballast further added following their performances at the Brno round. Brno Championship Racing winners Romain Grosjean and Thomas Mutsch in the No. 5 Matech Ford will carry 40 kg (88 lb) of ballast for the second time this season, while the No. 7 Young Driver Aston Martin, No. 13 Phoenix Corvette, and No. 23 Sumo PowerNissan are also carrying with ballast.
