Ladder bar leaf spring guys

[joespanova]

I want to get the car to "wheel stand" without changing the ride height of the car. If I drop the front of the bars down one more hole , which naturally increases the pinion angle also , without moving the housing down , do you think it makes the car more wheel stand prone?
There is a point , I guess , where dropping the bar down becomes counter productive and you just HAVE to change the ride height.

Raising the front of the bar will make it want to wheel stand more.

Not necessarily. That depends on where he is at now? Raising the bar moves the instant center rearward and higher and hits the tire harder. That may or may not make it try to wheel stand more?

Really not enough information to answer the question. A good general starting point with ladder bars is make the bottom bar parallel with the bottom of the car not the ground. Give it 2-5 degrees of downward pinion angle and see what happens.

This is good information. The higher into the chassis the front of the bar goes, the more tire hit, because you're getting less "leverage" against the chassis. The result of that loss of leverage is that the tire is driven into the track harder. The other side of the equation is that when the front attaching point of the bar is lowered, the car still may not wheelstand a great deal, because it simply may not have enough power to "lift" the chassis.

Without changing the ladder bar location is the rear end housing floating on the leaf spring perch? if its too tight then it's binding and this will kill your effort. . Luke SS311

No , everything's loose and oiled ( WD-40 ).

If you are not using floating spring perches, it is binding. WD40 is not a good lube. I ran ladder bars with leaf springs back in the '70s. On 10.5" tires. Hooked better when I went to mono leafs, then still better with the floaters.

Ed , of course I'm using floaters.......and they are not binding.
I'll move the bars up a hole and see what happens............for some reason I always assumed going down makes it more wheel stand prone......

Use some good moly grease to lube everything. Mine was a C/Super Modified '69 Camaro. 302" on 10.5" tires. Making it wheel stand was never an issue. Don't think I ever moved the bars up or down.

Just don't move the bars past level with the bottom of the rocker panel. Mine has a down angle of 1-2 degrees. Horsepower and good chassis is what will make the car get up in the front. Moving the bar down will make it hit the tire harder.
