A laptime of 1:49 on the RedBull Ring GP track, Traffic got in the way, I think the car is capable of doing a 1:47 or 1:46 with later shifting and no traffic, as well as throwing out the passenger. A 1:44 or 1:42 would probably be possible with the larger brakes. After tuning the car is much more capable than the first video posted on this channel.
