Staggered-width 20″ wheels are finished in black and wrapped in 245/35 front and 295/30 rear Michelin Pilot Sport Cup 2 tires. The GT4 used the front suspension from the 991.1 GT3 as well as a specially-tuned multi-link rear setup, Porsche Stability Management, and Porsche Torque Vectoring. Stopping power is provided by optional Porsche Ceramic Composite Brakes with yellow calipers, and a fluid flush was carried out in February 2021.
