‘It was a disaster’: Timo Glock eyes turnaround after Dorr McLaren Changes

McLaren changes target key weakness

Addressing Glock’s feedback was central to Dorr Motorsport’s winter development programme, with team manager Axel Funke highlighting a lack of feedback at the limit as the driver’s main concern.

“Timo’s biggest criticism of the car is that it provides very little feedback at the limit,” said Funke. “You suddenly lose grip, and with it, confidence and the sense of how far you can push.”

In response, the team worked in coordination with the Deutscher Motor Sport Bund (DMSB) to modify the suspension kinematics of the McLaren 720S GT3 Evo, aiming to improve drivability and tyre warm-up through a softer set-up.

Within the FIA’s strict GT3 homologation framework, the team utilised permitted tolerances of plus or minus five millimetres at the suspension mounting points. By flipping a bracket that connects the wishbone to the chassis, Dorr effectively shifted the geometry within those limits.

“We’ve just shifted the zero point,” Funke explained. “The centre of the pyramid is at plus three - now we flip it and it’s at minus three. That creates a six-millimetre difference, so we simply commit to never mounting the bracket in its original orientation again.”

Further deviations under DTM regulations

Additional changes include reprogramming the ABS system, which is allowed without re-homologation, and switching brake supplier from McLaren’s homologated partner Alcon to TM Performance for the 2026 season.

Funke described the move as both a performance and financial decision, with added sponsorship playing a role. The switch is permitted under DTM-specific regulations, which allow certain deviations from FIA homologation provided approval is obtained from the DMSB.

To ensure fairness, Dorr has agreed with rival teams to use TM brakes consistently throughout the season, avoiding any circuit-specific changes that could influence the Balance of Performance.
