    got a bad case of front wheel wobble after slowing from burnout. the cars 125 inch wheelbase and it does have a steering dampner. spindles are cut down early ford type., with the arms all part of forged spindle.caster is at 10 degrees and toe end is 1/8 inch. it has a front axle offset, 1 inch,and has a torsion bar front . front tires are 24 inch tall with no brakes. has a strange funny car type steering box and is center steer. steering arm off left spindle is 6 inch center to center. this all started after spindles, which were mounted backwards, were changed around to come off back of axle to correct the ackerman because of the reverse akerman and made car hard to turn. now the inside wheel turns sharper than the outside wheel for the correct akerman. early ford type spindles can onlly be mounted one way , behind axle for the correct akerman. car turns easier now but should it have more caster, which will make it harder to turn ,or less caster to correct that wobble after slowing and on brake? It is connected by all heim joints which are new. the dampner is a S and W adjustable type, the same that moto cross bikes use and is on its hardest setting. 50 pds preasure in front tire, 15 by 3.5 wheel

    the car is a friends and he bought it with these ford spindles in place. I measured the caster with a degree gauge off of the front flat of the spindle. all the kingpin bushings seem tight and the drag link support is tight. the torsion is bolted direct to the axle , no bushings, if thats what you mean. the spindle steering arm for the drag link is steel and tig welded to top of spindle. do you think more caster needed or less? thanks for your imput.

    Try running less toe in. bring it closer to 0. i know if i try running 1/8 toe in on my car it will rip the steering wheel out of your hand after the burnout.
