Got a 76 camaro, I am looking for front end geometry setting that will help me get this thing under control. The front end is just sloppy into the turns and I need to try to get it handled. Can anyone help?

Start with a good rebuild of bushings and ball joints will get rid of the slop then someone should have some camber caster for camaro's on here toe out around 1/8out

Good start point is replace ball joints/bushings, a little trick to grind off a little of new lower bushings till they "fall" under their own weight bolted in, and use some grease to help in that matter, also the low friction ball joints(taller ones on both sides) work very well and I recremend them. Whatever you can get out of the LF for positive camber do it, but not much more than 2degrees, late 70's caddy LF uppers are longer and taller than camaros if you must use stocks uppers. 3.5 negative on the RF (pending on tire wear/tire pressure) caster 4 RF/2 LF 2split. I shoot for 3/8inch toe out but between 1/4-1/2 inch is good. Don't forget to divide your difference on your measurement in half, for that is your actual toe (example: 1 inch difference is 1/2 inch toe) as I said befor, the suspension should have very little friction if any, I build my front end without springs/shocks and cycle them to look for any binding and fix as necessary. That should be a good place to start. Hope this helps

Leaf4life, I'm curious about your theory on toe. Why do you divide the number in half? I was always taught toe is the difference front to rear, not front to center. Just asking because I have never heard of this and I've been in racing for well over 20 years, dirt and asphalt.

You have to divide it because its between two measurements.

"Toe out is the difference in distance between the front of the tire and the rear of the tire. A slight amount of toe out is desired on a race car. Toe out is adjusted by changing the length of the tie rods. If you desire 1/8 inch toe out , the measured distance of the front of the tires and the rear of the tires would be 1/4 inch. Measure the front and rear distance between the tires and divide by 2 to get the amount of toe out."
The first and third sentences are direct contradictions. If the toe is the difference between the front and rear, then subtract the rear from the front. No dividing by 2, unless you are wanting the toe for just 1 tire.

Yeah, I center my drag link and right tie rod to straight by stringing the right side. With the idle arm and pitman arm squared and adjusting the right side tie rod as close as possible to straight. mark in the center of subframe and draglink. then get the left in the ball park.i do all my adjustments toe wise on the left. I'm not trying to insult you it's just what I was taught years ago and have had great success with it. If you have a different way that works good for you, then that's great. ;D

out 1/4" run a 850-900 rf spring. 900-1000 on lf spring.

i agree with leaf4life , that way you always have a reference point .

You guys!!!! If you can get serious! I run 1" on wide tires and 3/4" on regular ones and you have to roll the car to and fro and back to center of that and measure in the center half way up! It all chances when on the gas or brake plus all that technical stuff when turning and rolling over! Looks good on the track and with a new trophy!
