Our PB of 1:56.39 at Sonoma Raceway in a 981 Boxster GTS on PS4S tires. Unfortunately we once again delaminated our front PS4S tires.

Video recorded using the Track Attack app with our recommended windshield mount and OBD BLE dongle (see www.trackattack.app) and HR via the Track Attack Apple Watch app. External GPS used is the RaceBox mini (use code TRACKATTACK15 for 15% off).
