Custom triangulated 4 - Link questions.

[sinned]

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.
