Lieb had previously studied automotive and motor engineering at the University of Stuttgart for two semesters before choosing to focus on racing. Lieb completed his degree at Esslingen after seven semesters of study and has subsequently combined his racing with a role as an engineer at Porsche Motorsport's workshop in Weissach.

In 2005, Lieb returned to the FIA GT Championship where he won the GT2 Drivers title with Mike Rockenfeller for GruppeM Racing, netting a class win at the Spa 24 Hours along the way.

In 2009, Lieb teamed up with Richard Lietz in the Porsche 911 of Felbermayr Proton in the European Le Mans Series. He won the GT2 class championship with three wins in five rounds. On his return to the 24 Hours of Le Mans, running for Felbermayr-Proton alongside Lietz and Henzler, he had to retire.

In the American Le Mans Series, he was fourth in Sebring and 5th at Petit Le Mans as third driver of Bergmeister and Patrick Long for Flying Lizard, and came second at Miller with Henzler for Farnbacher-Loles' team, always in a Porsche 911 GT2 class.

Lieb and Lietz successfully defended the drivers and teams titles of GT2 class in the 2010 Le Mans Series, with three wins against two semi-officials' Ferrari F430 of AF Corse.

Counting Henzler as third driver for the fourth consecutive year, he finished fourth in the GTE-Pro class at the 24 Hours of Le Mans. In their participation in the 12 Hours of Sebring for Flying Lizard, again accompanying Bergmeister and Long, he finished in sixth position. He did not race Petit Le Mans, although in the 24 Hours of Daytona, where he finished sixth in the GT class in a Brumos' Porsche 911. He also returned to win the 24 Hours of Nürburgring for Manthey, forming crew with Bernhard, Dumas and Luhr. He also returned to pair with Alex Davison, but this time at the invitation of V8 Supercars to drive a Ford Falcon in Surfers Paradise Grand Prix, finishing 23rd and 18th in each race.

In 2012, Felbermayr-Proton left the European Le Mans Series for the World Endurance Championship. Lieb continued teaming up with Lietz in the team. He earned two wins and six podiums in eight races, whereby Felbermayr-Proton finished third in the teams championship and Porsche concluded second in the manufacturers championship. He also finished third in the 24 Hours of Daytona, again in the Brumos' Porsche 911. On the other hand, he returned to Surfers Paradise but this time drove a Holden Commodore, finishing second in the first round and 14th in the second.

Porsche officially entered in the 2013 World Endurance Championship, and Lieb was hired to drive one of the new Porsche 911 of Manthey alongside Lietz. Both, along with Dumas, won the 24 Hours of Le Mans, and captured five fourth-place finishes, one fifth-place finish, and one sixth-place finish, counting Dumas as third driver in the first three rounds. Thus, he was fifth in the Drivers' Championship, and third in the teams and makes.
