S14 suspension question

[pr0ject TRUENO]

Ok so here's the problem...I just installed some Kei-Office coilovers and took a brief drive. I noticed that after going over bumps, instead of the car going up and down, it feels as if the car is jolting side to side. FYI the steering wheel doesn't move; this feels as if it has something to do with the rear suspension...it's likely that the culprit could be the subframe bushings, but I just wanted a second opinion since this problem didn't happen with my old suspension. Although you should note that my old suspension was 100x softer. Tips?

subframe bushings, rucas and an alinement should do the trick... it's a combination of all of those things. You should add that you probably slammed the crap outta your car... if it was just mildly lowered you wouldn't feel it so much.

Mildly lowered this time :)

very common thing to feel if youve just installed coilovers on the car, lowered it, and you haven't aligned it yet.

add the appropriate mods if any and align it to spec. ask again if its still doing it

Bumpsteer. Adjust it out with new tie rod ends.
