DO NOT MAX OUT YOUR GEAR RATIOS!!!!!!!!!!!!! Too much drag will be on your car after 140 mph, and ur car wont even shift into sixt gear if you max the gears. What you should do, or at least what i did, is put your settings to the rigth and go check in qualifying if your car tops out. If it does, put it to the right a little more, if not put it back to the left a little more. The max speed i reached, and it can go faster, was around 185 mph. I overlapped the other guys so it means you shouldnt have a problem. If you max it out, i didnt even max it out all the way with the settings, it wont shift inot sixth gear. U can do it but your car will not accelerate, but decaccelerate. By the way, good luck with that race, the most boring thing i ever did.
