I have the bow ties. They seem to stick pretty good in the dirt. But to the guy who says he strips out the spur gears all the time, he needs to learn to set the gear mesh. I'm using the original 70 t that came with the car. I did blow out the outdrives once though. But I like to have the power when I want to test my driving ability. I do want a Jato though. I am selling my rusty on ebay to raise funds for a jato. The boss only allows me to have one at a time. Damn!!!
