How much caster is the most caster? or what degree of caster is that? Roughly.the front one turned all the way out and the back one in the middle, or the back one all the way in and the front one in the middle. sounds dumb but you get the most caster that way . use the one in the middle to set camber. biggest problem is if the car was ever tweeked. I did a challenger a while back , set them like I said , put it on the rack and the pass side was really close and the dr side way off, turns out the frame was hit on that side.
I took your advice today, with middle in front and all the way in at rear, and discovered the geometry on these cars are not exactly perfectFor a general suggestion, I like more than 2 degrees of caster and between 1/2 and 3/4 degree of NEGative camber.
My baseline setting is always to adjust the front cams all the way out toward the fender and the rear cams in toward the engine.
Caster and camber are directly related in these systems. Often, due to the design, it can be hard to get enough caster without the camber going positive. 2 degrees is okay but more is better. I would NOT want any positive camber though, not if you intend to turn corners with any decent speed. Cars with positive camber and soft stock suspension often tend to scrub tread off of the outside edges of the tires when cornering. A little negative camber hurts nothing yet improves cornering power because when the body leans during turns, that negative camber tilts outward to positive.
I don't know how it happened but my 70 Charger was able to align to 4.5 degrees of POSitive caster, .75 degree of NEGative camber and 1/8" toe IN.....all with stock replacement parts. It steers great and the front tires do not wear unevenly despite some real spirited driving!
I think they are a Moog item. I installed them on the rear of my upper control arms in hopes of improving caster - and by design they did (provided they are installed correctly). But, to gain maximum advantage to caster they need to be installed front and rear - installed to move the front of the a-arm outboard and the rear of the a-arm inboard.I read about offset bushings to get better caster/ camber adjustments. Anyone know about them? Thanks
