Leon Posted September 25, 2012 Share Posted September 25, 2012 (edited) These are not progressive rate springs. I'm running the bump stops provided in the full bushing kit. It is possible that the car is bottoming out, but when I run on 1 or 2, it seems to bounce TERRIBLY. Like it just gets in rythem and stays there. Sounds like a damper issue to me. You are having to soften the Tokicos, which have very stiff compression damping, a lot in order to be comfortable. However, given the "bounciness", this says that the spring rate/damper combo is now very underdamped, meaning that the damper has less control of the spring/mass. A damper with relatively stiff low-speed damping but softer high-speed damping should still perform well, while riding better. I'm hoping to find a damper that can accomplish this and accomodate a Z coilover install as well, as my Z has Eibachs/HPs now which ride rough and have very little bump travel before the ES poly bumpstop (which I haven't cut, yet). The nicer bump stops should help too, if you hit them often. Just take a look at a bumpstop some time and it will be pretty obvious whether you're been riding them or not. A lower unsprung/sprung weight ratio will improve ride and generally decreasing unsprung weight (wheels, tires, brakes, some suspension parts, etc.) will have a positive effect on ride, handling, acceleration, braking and traction.

RebekahsZ Posted September 25, 2012 Share Posted September 25, 2012 An easy way to see if you are bottoming out is to put a long bread-tie type twisty tie around the strut rod and see how much it gets pushed up. Kind of a "tell-tale." Quote Link to comment Share on other sites More sharing options...
SUNNY Z Posted September 27, 2012 Author Share Posted September 27, 2012 I don't think its bottoming out, as my bump stops haven't kissed the gland nut (that I'm aware of) Quote Link to comment Share on other sites More sharing options...
JCan Posted October 26, 2012 Share Posted October 26, 2012 All. I recently purchased tokoko illumina springs and shocks. The insrtuctions suggest that u cut the stop in half before installing. My car isn't on the road yet so I can not comment as to the ride... FYI Jim Quote Link to comment Share on other sites More sharing options...
