Triangulated 4 link question

[mitch_04]

Hi everyone,
First off I'd like to thank everyone who posts on this site, I've learned a lot by browsing around. I'm about to build my first triangulated 4 link, although it isn't going to be on a pro-touring car. The suspension will be on an 85 C-10. My question is about the upper links. I have read that you do not what the axles upper links near the frame, you would want them near the differential. The reasoning for this is, I believe, that it would have an infinite instant center.

My question(s) is this: If I were to mount the axles upper links near the frame, what would the "seat of pants" difference be while driving? If I could go this route I would be able to mount longer links at a greater angle, helping me stay centered throughout the entire range of travel. The pickup will be bag on bar, and my main goal is to lay frame for shows with my secondary goal to be getting the best geometry available without hindering the main goal. If I have to go with the links near the differential, I would have to go much, much shorter since the frame is very narrow.

I do plan on building a pro-touring third gen Camaro, but until I find one in my price range I will learn on my pickup project.

Thanks for the help,
Mitch
