This day comprised of a drag and sprint component. Each competitor had two drag runs, one on each straight of the circuit.

Drag
Best run (according to RaceChrono):
60 feet - 2.43 s
1/4 mile - 14.49 s @ 157.1 kph
0-100 kph - 7.19 s

Sprints
Tyre pressures that worked for me: Front - 34 PSI hot, Rear - 33 PSI hot.
Tyres: Dunlop D03G/D02G
Brakes:
- First time trying Ferodo DS2500 at the front, they held up very nicely.
- Also got some titanium shims for the front, brake pedal still felt spongy after each session though.
