Right after a track day at Blackhawk Farms Raceway where the Z4 dropped its best lap time by 2 seconds, we visit Jefferson Speedway Track Attack on the same RE-71RS tires (+M3 front control arms) and improve the Z4's best time by 0.7s (down from a ~40.2) and improve on my PB in the 911 by 0.2s!!
The track conditions were perfect today. Shout-out to Jeff who set a new lap record (37.4xx) in his white Audi TT RS.
