the deal in getting a car to go 300mph in the game is really simple believe it or not...
all i got to do is pick one of the last 2 cars in the game max out the performance parts for the car
then in the middle of a race or while in free roam
press start there should be an option that say performance or something along that line click on that and move the areodinamics all the way to the right..now having done that continue with the game
get to a nice long straight strip of road max the speed of the car out then burn the nitro and if u dont hit anything to hard u will be able to hit 300 plus MPH...
