Practice sessions for this weekend’s F3 Masters race at Zolder kicked off today in pouring rain, with the morning session shortened to 30 minutes and the afternoon session largely washed out. Christian Vietoris was quickest for Mücke Motorsport this morning, ahead of the ART duo of James Jakes and Nico Hülkenberg, while in the afternoon it was Ultimate’s Esteban Guerrieri who set the pace ahead of Atte Mustonen and Hülkenberg.
