Ok, there are a couple lingering questions I have about the WRX suspension, that I haven't found answered here (perhaps they are and I just suck at searching ). The suspension is described as MacPherson struts, with additions to the front and back, as well as funky "liquid" bushings. I don't have a WRX for inspection, so I can't go look at it, although I suspect someone here could describe it better than I could observe and speculate as to its purpose.
- Front suspension: What is a lower L-arm? What is it there for? Changing the camber is all I can come up with, but why and how?
- Rear suspension: Parallel link? What is that? (multi-link came to mind, but it's a MacPherson strut, and multi-link seems fundamentally different by all the reckoning I can do) Better question - what's it for? Are we talking the equivalent of a sway bar here? Is it still independent suspension, in practice (if not in marketing-speak)?
- Liquid bushings ... all I have ever heard about are polyurethane and rubber. What are liquid bushings? How do they compare to polys and rubber? (or are they polys or rubber?)
