Round 1 of Bimmer Challenge 2020 season opener at Chuckwalla Valley Raceway. I made a lot of changes to the car over the past few months – specifically weight reduction. Car should weigh in around 2,900 lbs with no driver and half tank of gas. I also added some RS Future front splitter diffusers to help with the front downforce. Last time I came here to run the CW configuration was when I had no aero and pretty much full interior so I didn’t really know what to expect, but today was good enough for a 4 sec faster PB.
