Due to having to cancel an early June event, hadn't run Buttonwillow since April and finally ran it this past weekend. 'tiz been way too long, I'm sure those who are familiar with Buttonwillow would agree.
Here's a video of a decent run from a not-all-that-stellar day at the track.

2011 E90 M3 Jerez Black DCT ZCP (Gone - traded in)
