I'm in the process of fabing up brackets for the silverado. This will be a "true" 4 link (with multi adjustment holes and rod ends). Based on calculations, I can get anywhere from 65% anti-squat to 175% anti-squat (I plan to start at the 65% setting to prevent brake hop). I have 2 2600lb air bags that will support the rear and should give good ride quality.

I'll progressively attach pictures throughout the build.

The current pictures are the "mock up" of the front brackets. Everything is 1/4" plates that will bolt to the stock front spring hanger location and then be welded (the bolts ensure alignment). They are only lightly tacked at the moment as to check all the angles, make the triangular gussets, and make sure everything is spot on. Then I'll weld everything up nice and strong.

 

What does "true" 4 link mean? Will this be street driven? or track only? I assume track only since it looks like your running hiem joints. Looks good so far, lots of adjustability.

 

Nope, it's my daily driver.

I prefer rod ends on my setups since they provide positive location and eliminate "mush" from compliance. I have never understood why people complain about "noise" from rod ends. I used them exclusively on my Camaro and my car was silent.

When I say "true", I mean an adjustable link system with numerous options vs. the "4 bar" setups that have one setting with no adjustment capability.

 

a 01 camaro all motor needed a 4 link? dont stock suspension go into the 7 and 8's?

anyways post more pics up of the build

 

do you mind explaining your choice of 65% anti squat? Ive helped do setups on some fast full drag cars and even analyzed a couple year old NHRA pro stock car. All seem to be in the 110-120% range. I see you mention brake hop. im assuming a high a/s number will cause the rear to do something funny under breaking in a street car.

 

cool pics, im interested to see how it turns out

 

initial post:
The camaro has a 3 link along with C5 front spindles and a full tube frame (though it won't be all motor either).



65% is simply a "start point". Since I'm not looking to drag it, I'm more concerned about overall performance (both accel and breaking).

While high a/s % is good at the track, it can have negative results on rough pavement. As the a/s % increases, compliance under load decreases.

In road race and auto-x setups, anywhere between 65%-75% is usually seen as a good initial target since "from a dig" acceleration isn't the main goal. It gives reasonably solid acceleration while not showing any of the annoying side effects of short instantaneous center problems.

Hopefully I made that clear enough (felt a bit long). So short answer again, 65% is simply my start point. As I stated in the beginning post, working the numbers I COULD get upwards of 175% a/s if I REALLY wanted to. I'll drive the truck for a while at 65% and then perhaps start playing with it over the coming months (I can never leave things alone anyways....no reason to think this should be any different..lol )

 

More pictures (actually a few days old now). These are from the initial "test fit" of the bracket (thus the 2 bolts positioning it. All 5 bolts have since been installed (to lock it down) and the bracket was then welded to the frame permanently.

 

These are off the rearend getting the old (leaf spring/shock) brackets cut off and then prepped to weld the 4 brackets. (Note: the T56 sitting on the tranny jack in the background... summer project )

The rearend is currently under the truck with the 4 link bars connected, the bags sitting in place, and awaiting the panhard rod mount welded on the frame (tomorrow morning's project). I have been lazy with taking pictures however.

 

Are you putting them on the outside of the frame rail? I know it is better but most people put them on the inside to tuck bigger rubber.
