Custom triangulated 4 - Link questions.

[x-tream]

I am building a custon triangulated 4 - link in a 70 cuda, and a 68 camaro. I am wondering what the proper down angle, and side angle of the top bar is the correct. Also is there an approprate lengh for the bars??

There is no answer. Designing suspension is far complex than just "what angle do the links need to be at". It takes hundreds of hours of both trial and error on the actual chassis combined with taking measurements and analyzing the results via an Excel based program.

I don't mean to sound harsh but if you asking what angle the links should be at you really have no business touching the torch or MIG yet. Spent a few months learning, searching, reading then do some measuring of what you have now and analyze that to get comfortable with the different programs as well as taking very precise measurements of pick-up points. After all that map out a plan and post you results, there are a few who will be happy to take a look at them and give an idea of how it looks on paper.

Give us a call, Mark. We've got a DIY kit that can be installed under most trunk pans. You get to decide where the brackets go, so it's all up to you.

Well i have built straight 4-link , ladder bar suspention for 500hp plus cars with out trouble before. We know have two cars in are shop that are more interested in pro-touring then drag racing. The reason i am asking this is because every picture i see is different. Since u say there is so much to read and understand, were can i find this information? My other option is to build it and see how it works. Which is not really how i want to do things, that is why i am on here asking people who have done this before.

Milken, Steve Smith, Herb Adams, and Fred Puhn will get you started.

Drag suspension is easy...just run a few parallel links and hang on. Things like roll oversteer/understeer, roll center height, brake hop characteristics, SVSA, and articulation are not usually considered.
