I would like to know what angles you can have on the top bars of a triangulated 4 bar. I have mine set at 30 degree. Ive heard that they have to be 45 degrees but I have done them with stock rearends that are not . I want someone to tell me what they set theres at if they did them yourself, and how they work. no one in my club seems to know and I would like to let them know what has worked for other people. Thank you.

Actually, a good place to start is a local speed shop/ garage. Look for those who have race shops and actually build serious muscle in your area. These guys will have the real answers for you, and you never know, they usually will offer you pointers on what to avoid. Mostly from experiences at the track.
Each set-up is different on every ride. It mostly depends on the HP rating of your engine and the driveline combination. So, there really is no set in concreate answer for your situation. Many veriables to work with.
Length of drive-line, type of chassis set-up, meaning if you have a heavy modified rear section on your build, or is it a factory design you are modifieing. These are just a quick sample of the veriables to throw at you. Plus, the type of four link you are adding plays a big part into your final answer. With out seeing the set-up, we cannot give you everything.
Sorry for sounding blunt on your question. Good luck on your build.

What types of joints are you using? Quality spherical rod ends could handle less triangulation than rubber bushings. Off-road guys have found that 40 deg included angle (20 deg. each link) is about as low as you can go when using very stiff links (2" .375 wall isn't uncommon) , brackets, and strong rod ends.

Thank you. I have 30 degrees on each top bar. So I am thinking I am alright on a 350 stock crate engine in a custom cruzer. I have no need for power starts or cornering. Thank you again.
