I think the benifits are self-explanitory. You get to spend a buttload of money for push-button changing of suspension stiffness, instead of getting outa the driver seat and taking 1minute to adjust your top-adjustable suspension. Then again, if you have top-adjustable suspension, you allready spent a buttload. Go for it.
What isn't stock-looking about top-adjustable non-tems suspension on an mk2?
TEMS is really easy, could be adapted from almost any car, just need to have all the wiring, servos, and control module. The big punch to your pants is going to be finding struts/shocks that are A.) top adjustable, and B.) in the same degree range as the servos you are using.
Its great that you found that sheet, it really is. I just want to know your rationalization between TEMS and manually top-adjustable suspension, where one is for "factory look" and one is for "race". Samn damn thing, just one manipulation of a control, instead of 4...
Honestly too, finding that setup to stick on your car is impossible. I mean, really... You would need the struts/shocks, top mounts, actuators, brackets, all wiring, and the control module. If you did find it, would have to be shipped from JAPAN or something of the like. BIIIG $$$ for all that jazz. Not to mention what happens when you need replacement struts? Goodluck.
Its not an "option" if its impossible to find... Yes, TEMS is an option, but fully custom would be easier to find/purchase than that factory setup.
If it is from a MX Cressida, then they are not going to be easy to find. According to my 85 Toyota Press release information, they were available on the 5-speed Cressy's. Not sure if they were available on 84's or 86's. And 5-speed Cressy's are not exactly easy to find, about 95% of them are Automatic's.
the really sad thing is about a year ago i saw a cressida 5 speed with tems and thought nothing of it. it was crushed a looooooong time ago. if i ever see another one ill look into it. might be nice to have on a daily driver. certainly would make it a unique mkii.
