Wheel alignment

This an old article on alignment I came across this morning. While it's a good article, I found you can't hit these numbers on caster and camber without tubular control arms. I was able to achieve the typical street performance numbers from the chart using tubular arms on a 68 barracuda I had several years ago but with stock UCAs, you can't get close.
Anyway, what are your thoughts on the chart and are you using factory specs or going with your own?

you need to install K7103 Moog Offset Bushings to your a arms to achieve those caster numbers in the chart.

If you installed them like the instructions in the package they might not help you much. The Moog intention of the bushings are for rusty cars that have sagging frames that bend inward over time.

The "trick" is to install them like this diagram below and ignore the Moog instructions. The arrows will be pointing opposite directions front bushing to rear bushing.



First make sure you set the ride height first to what you want. Factory manual alignment specs are no good for radial tires, they only work if you use bias-ply tires. For Radial tires, Camber -.50 to 0 degrees, Caster as much positive as you can get up to 3 degrees and toe in 1/16th to 1/8th inch. Car runs down the road straight as an arrow now. You will be limited to what you can do with stock A arm bushings, but if you have the Moog off set A arm bushing you can tweek it a little more.

Firm Feel also sells those bushing

I've also made shorter strut rods to help gain caster. Additionally depends on chassis rake. For every degree of chassis rise in the rear at static height, you lose 1 degree of positive caster. With offset bushings in the front only and 1 1/2-2 degrees of chassis rake you can usually get 0 camber and 2-3 degrees positive caster. I've aligned hundreds. Occasionally the stack-up is bad and you cant achieve those numbers. 2-3 degrees positive is plenty of caster. My drag car has 3 degrees chassis rake, 2.5 positive caster. Drives fine at 150mph with stock front style suspension.
