    It's been discussed on NICO. I *THINK* they're motorcycle coilovers. I'm not sure how high the quality is on that setup.

    Suspension geometry isn't all that simple. I wouldn't trust it personally.

      Those are shocks off a 07 Yamaha R1. They run roughly 8.5kg/mm springs IIRC. It might be closer to 9kg/mm. I dont see any real useful benifit from it.

        Looks like a decent way to add weight in the rear and increase the center of gravity.

        This falls under the category of: "just because you can, doesn't mean you should".

          other than clearance, would it not give the ability to run longer springs or whatever springs and based on design not worry about any coilbinding or whatnot.... while controlling height based on rods? And would it not move the unsprung weight from the wheel to inside the car to not relaly be a part of the unsprung weight?

            Unsprung weight will go down, but I imagine total weight is going to go up with all that hardware. Plus I have to wonder how stiff that cross tube is with the bend in it. It's either really flexible, or really heavy.

            I imagine it'd not be that great unless the shocks were designed to work with the lower piston speeds(the cantilever has less of a motion ratio than the stock setup, so you're losing sensitivity there).

              Who has problems with rear clearance?

                I just don't think it is worthwhile. Sure it saves some un-sprung weight and I think that it can be done to save total weight too, easily if your car has a cage to begin with. I just don't think you will gain anything else though. I guess you could easily use much better actual racing shocks, which are not cheap BTW. The shocks that come with the setup are good enough to use, but I guarantee they are not right. Like def said it takes special valving for that low of a piston speed and travel, AKA actual racing shocks. That set-up is just not good enough to make it all worthwhile IMO.

                  It seems like there should be a support from the bend in the middle of the shock mount bar to the chassis.

                      This comment was made with some element of humor to it, primarily because the front is where most S-chassis owners have problems.

                          have you looked up the price for that shock yet?

                              I haven't but I bet it's like 800 bux a shock or more, none the less my point was to showcase something that is now doable on our cars. Hate on it or not but meh...

                              And about price, well people drool over the mention of ohlin's ttx shocks all the time on here so voila... some possibility...
