Porsche Motorsport has instructed its customer GT3 teams to shut off the ABS and TC control systems when running the 992-spec 911 GT3 R on track until further notice, DSC has learned. The German marque has moved rapidly to implement a solution to the problem for cars due to race this weekend.
This instruction adds to the drama for the car and follows multiple reports from customer teams of issues with the systems since its customer race debut at the Rolex 24 Hours in January. This has now apparently been tracked down by Porsche Motorsport, as Sebastian Golz, head of the 911 GT3 R project, confirms in a statement provided to DSC:
“Porsche Motorsport has informed all customer teams and owners that until further notice all Porsche 911 GT3R (992) type cars must not be operated while the ABS and TC control system are active,” the statement reads.
“The background for this is the ongoing analysis of anomalies identified in the wheel speed measurement system, which can lead to the erroneous measurement of the rear wheel speeds, and in turn cause errors in the regulation of the ABS and TC systems.
“Porsche Motorsport has successfully worked on a mechanical solution to secure the right wheel speed measurement under all circumstances. After the installation of the solution the use of the vehicle, including the use of the ABS and TC control system, is released again without any restriction.
“The provision of parts for the events GTWC Europe Monza, 24h Qualifying Race Nordschleife, Michelin Le Mans Cup Barcelona for this weekend is already being implemented.
“The further implementation for the following events is currently being planned.”
