If you're interested. They are posting a dragster mod this weekend at
RC mod.com .
The wheelie bar is actually an extra piece that used to come with some Bit bodies. It was to be attached to the front of the car to keep it from getting damaged when it went along the rails on the track. It would also keep the car from getting hung up as you went around a corner too fast. Now people attach the wheelie bar with a micro screw to the back of the car to give the car a pro dragster look or as storage for an extra battery cell or two. They look real nice once they are installed. It's also a very easy mod to do.
You can buy a wheelie bar from RCmod. You have to contact the admin at:
info@rcmod.com to buy it. It's not in the store yet.
