Drive through a desolate city in Utah, USA. The gravity upheld by this planet is similar to Jupiter and so it is very grippy. Make sure not to go offroad as a little jump can cause large amounts of suspension damagge now that the gravity is 3x that of normal. The SBR is the fastest version and should outrun most obstacles, just watch for buildings and bricks. You will need to maintain your speed on the jump at the end as the gravity will act against you. Also, the time is distorted.
