I have been struggling with trying to figure out trac bar and drag link angles and geometry, while also making sure they have plenty of clearance (at full compression/full extension and the full swing of the turning radius).
So I decided to make a really ugly 2D sketch on SolidWorks and now I have figured out my lengths and geometry.
For anyone out there also trying to figure out the best way to fabricate a drag link (DL) and trac bar (TB), the most important thing to do is to make the TB and DL as parallel as possible. Next, the most important thing is to make them as flat as possible (so lateral movement in the compression state = lateral movement in the extension state). Another important thing is to make them as close in length as possible...
