Find one point on the sub frame inside or out doesn't matter drop plum bob mark it on the floor. Go to the other side an the exact same location on the sub frame from the other side do the same plumb bob it. Do the same in the rear then measure between the two points on the front. Find half way an do the same in the rear. An you can chalk line the two center marks front to rear. You have to make sure your ok with your car setting in the shop where you make it until your done.
There are usually factory holes that were used to align all the sheet metal parts in the factory fixtures prior to welding. These work great so long as the car was never in an accident.
Couple of comments. String the chassis to find the centerline & measure 4 link chassis bracket locations to ensure they are exact side to side & front to back FIRST. If not, everything measured from there on will be off & you will have to start over. Using the string method eliminates measuring from ball joints (or other components) as well as if the car has staggered front wheelbase. Another reason for establishing centerline is getting wheelie bars square to the centerline. When there's rear steer the wheelie bars should be adjusted to the centerline. Another method of measuring pinion angle is to remove the driveshaft from the equation. Measure rear end housing angle & Engine/Trans angle then calculate from there. Great videos, thank you for sharing!
Good video. When you say that you can't use the 4 link to preload in a stock suspension car...do you feel this holds true even when you add a wishbone? In my experience, even a triangulated setup will be able to use the upper bars to preload IF you have added a wishbone to the "stock suspension" mustang or G body Thanks
There is an in depth answer to this in our previous "4 Link 101" video posted here on the channel. Check it out! th-cam.com/video/LECIF02_rCk/w-d-xo.html
Does't the rotational force of the driveline plant the left rear tire harder. The car squating on the right is just a byproduct of this and is decieving that the right tire is being planted harder when in reality its trying to lift the right rear tire.
You couldn't have nailed a better explanation better. As a guy who knows nothing about how to setup a 4 link I now feel like if I had one I could adjust it with some confidence.
So how bad or abnormal is it for an old car to be 1/2-1/4in off in triangulation to the front. How bad is it if my left bars will have to be 2-3 turns shorter than? Im really stuck on my rebuild, i could really use some advice
You guys make amazing stuff. My question is do you feel like your small tire 4 link kit would be a good choice for say an 83 chevy truck street/strip vehicle ? Or do you have a better suggestion? Thank you. Great video
Big help! Actually doing my first ladder bar set up on my ‘66 GTO. One challenge I have to overcome is the fact that I have the bare frame at my place, whereas the body is at my buddy’s body shop having rust work done.
I went to ADRS in 1983 in April Sacramento Cal. this is what I learned exactly 40 years ago and that was the dark ages of fourlink with over 200 ICs and CG that racers and chassis builders did not understand back then...great video
What is the most accurate way to find the middle of the car in the front? I have a stock susp. foxbody. Love the How To vids, thanks!

Hey guys, question for ya... what affects the car more, the anti-squat percentage or the instant center length & height???

Does a 4 link calculator also work for stock triangulated 4 link?
Do you guys have or do a 4 link for a 4th gen Camaro?
You couldn't have nailed a better explanation better. As a guy who knows nothing about how to setup a 4 link I now feel like if I had one I could adjust it with some confidence.
