Default rear 4-link confussion

i have seen a couple different routes to go, but still looking to find whats the best most efficient route. i have seen a couple kits offering parallel bar setups. some offering triangulated link setup.

what can i use to best work on my 70 bird? i am in the process of minitubbing right now, so i was wanting to go to link/coilover rear to help with lowering, handling, larger tires, etc. can i get away with fitting in a universal kit from jegs or summit? let me know thanx

Yeah...you can, there's a whole bunch that sell kits...S&W then there's
Chassis Engineering. I think they both work about the parallel bar setups. and triangulated link setup. Might be better off getting it though one of
them, they have tech lines.

Why not just move the leaf springs inboard, they sell offset shackles and frame connectors.

well i have it up and cut into with the mini tubbing, figured add the 4-link. more up to date, adjustable with my ideas of lowering, allows for larger rims/tires. relatively cheap upgrade, minus the work hours installing/welding.

Maybe Im just stating the obvious, but thats not a 4-link. As it clearly says, its a 4 bar. Nothing wrong with a 4 bar. They are very popular. But there's a world of difference when it comes to adjustability at the dragstrip between a 4 bar and a 4-link. No comparison.

ok im not looking for a full blown drag style set up, the 4 triangulated bar/link whatever setup, allows me to take advantage of the mini tub, coilovers, etc

Are you creating your own mini tubs or using the Detroit speed kit?

perfect. im actually going with my own version of the g-bar set up. GP, how wide are your wheels and how much clearance do you have with your frame rails and inner wheel. im going to make my links run off the factory front spring perch, and custom up a top bar/bracket to handle the inner bound coilovers and 2 upper links. i was hoping you could give me a bit of help with gap sizes of the room from your spring perch to your axle tube.

You'd likely find a LOT more info on these rear setups over at pro-touring.com

Those guys are seriously into making cars with the latest and greatest suspensions. Thats where I'm headed with the 73 bird I just bought from Mark L. I want it to handle like its on rails, with the idea that I may eventually do some road racing with it.

If I understand correctly the normal 4 link setups offer more adjustability than a ladder bar one, but neither provides a lot of lateral support. Thats where the triangulated 4 link setups and the 3 link ones come in. These latter are the direction I plan to take. Probably a triangulated 4 link with adjustable coilovers.

All those suspensions have been around for years and are not anything new, all the dirt track and roundy round cars have been set up that way for ages.

True......what I meant by latest and greatest is the availability of specific components off the shelf, and in many cases bolt in kits. For example DSE I believe just came out with a basically bolt in triangulated 4 link setup for the 70-81 F body.
