The second video in Sector3's custom championship series has been published on Youtube. On show this time is an intense race at the newly released Sonoma Raceway with the GTR2 class. As mentioned in the first part, Sector3 is preparing a revamp of the GTR2 class along with the custom championship feature. The car used in the video is, again, the upcoming Cadillac CTS-V.R, which, while not my favorite car, has a great throaty sound. Sound off in the comments below!
