Yeah it would be useful to make a 1 or a 1 and a half mile track so we can take our mod cars and see how fast they go and how long it takes to get it there without fliping it over..i have a Audi R8 for the FZ5 with the tweak and im doing about 175-180 mph before i hit the wall and im only in 5th gear and i have a whole nother gear to use
