Wheelie bar help
Looking for help in setting my wheelie bars. First time I ever had a car that will use them.
How far off the ground should the center of the wheel be with the driver in the seat? And should they be staggered due to the weight of the driver? 3300lb. car, back half, 4 link, bracket car 865hp N/A - No power adders T-400 with brake Dana 60, 4:11, Spool Thank you, Bob

its all trial @ error, got to give the car what it wants, mine are longer than yours and they are 6in off the ground to the center of the wheel bolt, with the r.h. side being a 1/2 in lower

I agree about trial and error. I set mine up blind and they've worked fine so far. My only spec was they had to be short enough that I don't trip on them every time I walk around the back of the car.
 I'm not able to make specific measurements on the car right now My set came spring-loaded, but I removed the springs and replaced them with solid pipes to reduce flexing. Jim

[QUOTE=twooldgoats;5901724]I agree about trial and error. I set mine up blind and they've worked fine so far. My only spec was they had to be short enough that I don't trip on them every time I walk around the back of the car.
My concern is that if I set them to high will I do a giant wheel stand (Not what I want) or set them to low and unload the rear tires (Creating a dangerous trip down the track, also Not what I want) . I see the guy's that have those big power builds with real long bars set the wheels pretty high, that's why I gave the size of mine to see if anyone could give a starting point with shorter bars. I don't trip over mine. lol... Bob,

It's been ten+ years since I built my car and, as I said, I'm not where I can measure now. I do remember calculating how high the front of the chassis would have to come up before the wheelie bar wheels hit, but it was only a rough estimate. If you watch the rear view video of my car in my signature (7.75 @ 178) you can get a good idea of the distances and see how they function during an actual pass. The attached pic of the launch from the front is the same launch shown in the video.

One thing I noticed on the "street" car on Outlaws: the wheelie bars are very long.
More adjustability? |
