MM5700 in T4

Oh, I forgot to mention this. When doing speed runs, you might want to wrap the inside of your tires with a double layer of duct tape. Be sure the clean the insides of your tires to get a good stick. This will help to greatly reduce the ballooning of the tires. This isn't so much for purposes of gearing as it is for keeping control of the truck. It gets really hard to steer when you're hauling butt. It also helped to keep the tires from tearing off of the wheels. Just keep in mind that the tape will let go at some point. For me, the tires were usually worn out by the time that happened.
