Do you not see anything other people have posted about Northstar? Rebelracer even said the track is coming apart. It is known they don't prep for test and tune sessions, so I'm not sure where you are getting your info from.
Say what? I don't know man. Its either my stock tires are hurting me that bad or the track prep is terrible. I have in car footage of me going sideways on the track in 3rs gear.
