Rear suspension is hard to learn because all of it lives under the car where you can never watch it work. I built this model so you can.
It's a fully articulated replica of the BRZ multi-link rear end. Every control arm adjusts, and you can cycle the whole thing through its travel and watch camber, toe, and bump steer change as it goes. Each arm is numbered, and there are reference marks for the OEM position, so you can pull a setup apart, get completely lost in it, and put it back to baseline in a few seconds.
What you walk away with is a feel for which arm does what. That's the part that's genuinely hard to pick up from a diagram, because on a real car you can only ever see the pieces, never the motion. It's a teaching aid rather than a setup tool, so it won't hand you numbers for your own build. What it will do is sit on an alignment rack, a shop counter, or in front of a customer who needs to see with their own eyes why the change you're recommending matters.
