4-link rear suspension
- Thread starter bashby
- Start date
I plan on building a 4 link for my car also. I have not even looked at it yet. I have built street rods before with both a parallel 4 link and a triangulated 4 link. The Sunbeam must wait its turn, though. Any photos and/or drawings would surely be helpful though. I have autocad 2004.
my thoughts exactly....
Packaging space is our biggest foe her. I am sure there is a solution where a triangulated 4 link works, but sometimes the easiest solution is the most elegant.
Been pondering this issue and I'm starting to think parallel 4 link with a pan hard bar is the way to go. Not as light but much easier to implement.

Rob,
I have been trying to sort out the parallel 4 link for a while now. I definitely don't think it is the easiest to install. In fact I think it is going to require a lot of cutting and reinforcing to access the upper link mounting point and to get the link to the rear end. There is a lot of room above the forward leaf spring mounting point however. My plan is to use the leaf spring mount as the lower arm mount and then go almost straight up from there into a dark abyss and just make it happen. This is necessary if you want mostly parallel, equal length links (which is preferred). I have all the parts starving for my attention, I just need the time, $$, and oh yah, time! I do however have a watts link already designed to handle the lateral control. All of this would go onto a new 8" Ford rear end.

My current trangulated 4-link configuration does not appear to need a Watts Link or Panhard Bar it does however negate (remove) about 1" of suspension travel in compression. I may decide to live with it and change the stops accordingly. It is simple and does not bind which is a good start! I am expected to go on travel tomorrow, I will post photos when I am able.

I had to cut the corner out of my battery box and make it a 45* angle for my upper right link to work. I cant remember exactly what the measurement was but from the top of the brackets on my upper links on the diff to the floor above was definitely under 3". I was worried about it bottoming out, but after a couple years and driving on some crappy Louisiana roads, and a couple autox's, its hasn't happened yet. 2-3" in compression is a good bit unless you have very soft coils.

I think mine are either 1&0 or 185#. I have double adjustable shocks and at the last autocross I would change settings every run and it ended up being best with the shocks on the lowest settings for both compression and rebound. Now if I could get the front end to be equal to the back end then maybe I would have a fighting chance against those pesky miatas.

The coil over shocks are single adjustable and I have posted a few photos of the installed 4-link rear suspension here:
