Long story short today I put nsx wheels on my s2k and wanted to lower it. Suspension setup is tein flex coils with the EDFC. I got the collars to move down and evened it up everywhere but the car didn't really go much lower. I've given it a couple hours to settle and still not much. Maybe an inch lower after lowering the collars about 4 inches. And on top of the car not being lower, it's ridiculously bouncy; almost to the point that it's un-driveable. I noticed that after I lowered the collars the springs didn't really de-compress much and there's a bunch of space between the top of the spring and the top of the strut. Is this normal? Should I do something specific with the EDFC unit? Could this be causing the car not to lower and/or be making it bouncy? Pleeease anybody with any input/experience lowering my specific setup- chime in I really want my car to be fun to drive and right now it's not

 

If you've got a gap between the top of the spring and the upper mount while the car is siting on the ground, then you're simply driving around on shocks that have bottomed out internally - essentially, the springs are dead weight and your shocks have no more compression travel left.

It's normal in that this is what happens when you lower a car too far, but it's not smart. The EDFC has nothing to do with with your shock travel or your ride height, its a gimmick to adjust damping "on the fly". A suggestion? Raise the car up.

 

That's what I was afraid of. I didn't the springs should stay compressed but haven't ever seen that before and didn't know if they would stretch back out. Thanks

 

word well i had never worked on a 3 perch coilover turns out i had only adjusted the preload and not the ride height. everything's fine and car is nice and low now
