Factory driver Preining won twice in Porsche's first season in the DTM last year with two-time Le Mans 24 Hours winner Timo Bernhard's operation, following up the Weissach marque's first series victory at the Norisring with a charging drive at a wet Red Bull Ring, while Porsche-contracted Olsen dominated from pole for SSR Performance at Spa.
Preining's move to join the incoming Manthey effort was predicted by Autosport last month and, with SSR switching to Lamborghini, announcing factory drivers Mirko Bortolotti and Franck Perera as part of its three-car roster on Thursday, Olsen has moved across to join him at Manthey following the conclusion of its works involvement with Porsche in the World Endurance Championship's now-defunct GTE Pro class.
