Rear 4 link numbers?

just running numbers into a calculator for link lenghts and locations, just wondering what numbers you are getting with your setups,
im in the process of doing a SAS using parts from another members rig I bought a long time ago. im designing the 4 Link in the rear, any help and pictures is apreciated
would love to see numbers/locations on the rugged rocks setup, but i cant seem to find any online.
so numbers like frame height, WB, CG, link lenghts and seperation, height links, anti squat. just to compare roughly to what the calculator is spitting out at me. any details is helpful

This was my setup based somewhat around the stock frame.

Thankyou, thats the type of info im looking for! My plan is almost the same as that but slightly different, wasnt going to triangulate the lowers, but the uppers were almost exactly the same measurements. Ill try to post a pic of my numbers im planning in a bit here

If you triangulate the lowers some, you will get that Roll Oversteer down. Right now, it will likely have quite a bit of body roll.

I would raise both of the frame mounts. As high as you can go on the uppers and maybe 1/2" less then that distance on the lowers. Unless you are targeting that anti squat number that is.
Sorry op this comment was on the one in the photo. On yours I would lower the frame lower mount or raise the upper just a bit to get that white diamond farther forward.

Drop the lower axle side down a bit to get more separation 5.5" is a bit small. 25% tire diameter is generally the guideline to go with. Sorry I didn't mention that before.

ok dropped the axle lowers a half to be 6" seperation, and raised the upper frame side by half inch, numbers stayed the same but roll ovesteer is 5. so I think I can pull this setup off on my rig and be happy, afterall its not a pro buggy or rocketship, just want it to have SOME road manners and not be all whillly nilly all over the place

You can aways use adjustable brackets on the frame side to give you more mounting options.
