The stock steering rack bushing are made out of old rotten 35-year-old rubber so we went ahead and replaced them with some of T3 hard urethane parts. These are replicas of the long ago discontinued TRD N2 parts. This will give our steering a more direct feel.
Stay tuned, we have discovered some rust and weak seam issues on our chassis that will need to be addressed before we can start assembling things. We will continue to show what we are doing to keep our old car relevant!

Well, that’ll do it! It’s actually interesting to me how many pretty well regarded cars moved to equal length 4-link rear suspension instead of… well, many other things. Not messing with setting anything up in CAD and going through the motions right now, but are there any issues with the upper links and lower links not being in the same plane, or “maybe in theory but not really”?
They have to be out of plane if you are going to have anti-squat which any 4 link needs at least a little of.
I meant in terms of the upper links being further inboard on the axle, to be clear; a lot of the implementation I’ve seen of, for example, 4-links under rally cars the box that was added here would contain top and bottom links instead of just top.
I suspect that some of this upper link stuff was done for interior packaging like it was on the FB RX-7 but ugh dealing with the consequences of that decision.
In this case, they are in the same location as stock. The factory doesn’t do this because they want to have a rear seat.
Mike, any thoughts as to whether it’d be worth using those boxes to add chassis rigidity if you’re converting to 3 link, or is it sort of moot at that point, since you’d be permanently tying the cage to the chassis at that point to provide positive location for the middle upper link anyway?
One of these days I’ll get started on my rotary 86, I swear!
You would have to do one in a three-link conversion. Don’t do a short upper link,
