Default Possible bumpsteer kit fix?

I have a 2000, S2000 that's on lowering springs & stock struts, running staggered 18x8 ~+45F 18x9 ~+50R; when I'm going ~50+ mph, the car feels like it's being pushed around. Whether I'm on a side street, freeway, whatever, it feels like the grooves of the road kind of force me to go wherever the grooves go. Or it feels like the wind is pushing me from side to side. The feeling isn't extremely harsh, but sometimes it does get a little bit sketchy.

After the research I've done, it seems that the problem revolves around a bump steer kit of some sort. But also the research says otherwise. Just curious if someone could possibly clear that up for me?
I've also never owned/driven anything rwd prior to my S so I wouldn't know if this is a typical rwd problem or not. Thanks in advance for help/advice!

I noticed when I first put on larger tires (255 width all around) my car would follow the grooves worse than before. I have bump steer kits front and rear and am pretty low, fwiw.

When was the last time your car was aligned? Excessive toe in or toe out and can make the car feel nervous like you're describing and any changes in the road surface would exacerbate it.

You have a blown shock, and it's performance is starting to degrade.

Check your tire pressure.

Re-invert the contapulous piston for the quantafurter. Or invest in an aphideral trapinslugmber, this makes seizing the fingaltrupermal easy compared to the conventional method of untorquing the limasphere bar. If all else fails inspect suspension for damaged parts and alignment before chasing this mythical kit.

I have never been so satisfied being trolled before.

Thank you guys for the insight though. I thought maybe it would be something like that, but I thought I'd get some input from fellow S owners before I tried to figure it out myself.

Well I say it's blown shock(s) because I currently have that problem, and I have the same symptoms you have. The right front is blown on mine. Luckily since they're stock shocks, you can just replace a pair and be done with it.

If you're a true masochist like me you can invest in a set of Koni Yellows, and drill out the top hat bushings and hole in the dust cover to 12mm. They're cheaper than OEM, and it's a replacement for the shocks, furthermore they're re-buildable unlike the oem sealed units, and can handle lowering springs better than the OEM shocks.

THMotorsports has them stupid cheap right now, I think it's like $134 for each of the fronts and $124 for each of the rears with free shipping.

Simplest explanation are your alignment , crappy and/or mismatched tire, tire pressure.
