Default Wheelie bar length question

I have decided to put wheelie bars on my 1967 Camaro. The problem I have is that I don't have a clue what the length should be. Sprung or un-sprung bars ? I will give you guys some of the basic info on the car...... It weighs about 3200lbs BBC makes about 825 hp on race gas,4.88 gear with a 33 in tall tire and its a ladder bar car. Any help would be GREAT !!!!

Default Wheelie bars

If the car has the stock front suspension then it is recommended to have the sprung wheelie bars, but if it has the strut front end with limited travel then go with the solid bars. The general idea is to have them about 50% of the wheelbase (in your case about 54-60"). The shorter the bars are, the more leverage they will have to try to lift the rear tires and create spin.

Thx for the reply.... The car has stock suspension although I have it tied down and it only has about 2-3 in of travel. Would you still go with the sprung in this case ?

Thx

With the car only having the front end limited to only about 2-3" of front end travel, I would go with the solid bars and not the ones with the springs and would adjust the center of the wheel to be about 6" off of the ground.

Here is a couple of pictures of a set that I built for a '68 Camaro from the ART kit. I stopped these right about the parachute, so he wouldn't be as likely to trip on them. The car runs 5.15's @ 130 in the 1/8th.

Hey Bill,
Not trying to hijack the thread, but what is the purpose of the slip joint cross bar on the top bars? Also i'm in the process of building a blown sm/blk alcohol Anglia with an ART rect. tube chassis streched to 92", i was seriously thinking about putting 72" sprung bars on it, i guess that sounds rediculas but i was thinking it would help stabilize the launch.

I think that the bars ended up being about 60" on the Camaro. The kit started out as the Pro kit #018904 from A.R.T. (www.appliedracing.com) with the 84" bars. It is a complete weld together kit as the feet where the wheels bolt-in comes in 4 pieces for each side.

Zip,
The top bars have left and right hand rod ends on them so that you can spin them to lengthen and shorten them. The slip joint allows for the fine adjustments and keeps the top bars from trying to separate when loaded. The slip joint is held in position on the top tubes by additional sleeves that are on either side of the slip joint and are welded to the tubes.

i wouldn't go past 84 inches...longer then 84 inches you get into other issues such as UNLOADING the car .
