Pro Touring 4 link setup

Wow, this is alot to take in for sure. I really wish I had access to the truck and could take some measurements.

Ok no crazy spacing on the UCA. That creates some problems. Without shorteing the UCA (which you said to stay away from) the UCA will have to run through the frame. I assume I can do this and just build a hole for each arm of the UCA to move through, but will take up lots of space on the top and bottom of where the frame is now. Doable but definitely on the little bit crazy side,

Another thought on this subject is do I need the UCA and LCA lengths to be the same or the effective lengths. With the UCA and LCA arms the same the UCA will have less effective length b/c it won't be parallel, so should it be longer than the LCA.

For camber angle, I was thinking between -1* and -2*. But I'd like to have a few degrees of adjustment. Any ideas on how to have some adjustability?

I also have a set of drop spindles for the truck. I had planned on not using them since the coilovers drop the truck about 3" in the front, which is not crazy but another 2" on top of that is getting to be alot. On the + side the drop spindles would drop the front but maintain the same suspension geometry, thereby raising the IC's and FRC (still below ground though) and lowering the CoG bringing them closer together. I couldn't say how much really without alot of measuring, which I can't do.

Sorry for the novel.


BTW bryce : Just realized why your name looked familiar. I watched alot of your videos on youtube. You care helped push me "over the edge". LOL Don't worry I won't tell the wife it was your fault.

Someone posted this on another forum I'm on. I made a couple of little tweaks to move the camber to -1.5* but left everything else alone. What do you guys think?

According to that I could see about 1 full degree of negative camber at about 30mm of droop. So I'd want to maybe use a little less static camber or is 2.5* total not to much?

I'm patiently waiting to see some pics of the actual work as I am going to 4-link my Sonoma with coil overs.

Well I've been doing some work. I've got the whole 4 link pretty much in but I cheaped out and went with some shorter bars. I don't like how the crossmember sits so I got some longer bars (30") and will be moving the crossmember forward about a foot or so. I'll post up some pics of the progress when I get done.
