Wheelie Bar Height Settings


Wheelie bar height

There are two different heights, measuring from the center or the bottom of the wheel to the ground. The first is the cold tire pressure height, You should always be on the flattest ground you can find. Some Racers will do this adjustment in the car trailer where the surface is flat. If you're setting them with the tires cold, and at a tire pressure that will be your standard, you should know what distance you want. We will call this the cold tire pressure reading. The drivers side bar should be 1/4 in. higher than the passenger wheelie bar.

The second reading is the height after the burnout. When the tires get hotter, they grow and the height changes. So, after the burnout see how much the wheelie bar moves up. Have a measurement that you use and go up or down on one or both, it just depends on the track and the wheel strike. We're talking very slight adjustments at that point. Know where you want to be within an eighth of an inch.

The strike marks are used for two reasons. Generally you'll have two strikes. You're going to strike them immediately, and then the car is going to get up on the tire. When this happens it will come off them, the front end will start to come up, and then it gets on them again. So, we're looking at the distance of those two marks. The first strike is very short. Remember to run stagger on the height. The driver's side a 1/4 inch higher, typically, than the passenger side because that's the side that is going to hit first. You can also tell by the width of the chalk how hard they struck. If the chalk is wide, meaning you hit hard, you'll want to raise them up a little bit. I try to keep the strike distance equal but with some cars this doesn’t always become the case. You can control the car from going left to right, but you shouldn't steer the car with the wheelie bars, that should be done with the 4 link, or a front shock or front coil adjustment.
