Default Car feels unstable going over sewers/dips/ect

Whenever i go over dips in roads, or the 'sewers' that dip into the road a bit, or anything where the pavement may have any kind of dip my S feels like its unstable.

my tire pressure is at 32 psi all around(hankook rs2's if that matters). stock everything.

does anyone else experience this or is there a way to fix this?

Is it an AP1? If so, this is a known characteristic called bump steer. There are a couple different kits available to help correct the problem, sometimes called BSK (bumpsteer kit).

Megan has one of the more affordable versions:

It would help if your car is out of alignment. If you hit a curb etc. since your last alignment it might be a good idea.

Alignments usually go out within 5-6 Months or 5-6K Miles, even quicker if you have after-market suspension regardless of the situation. You should have it checked, and try running a little less positive caster. That should reduce bump steer on stock suspension a little. But keep in mind that you may lose some steering feel if you do that.

BTW is it an AP1? What MY?

I agree with the alignment check that was suggested above.

It's a long shot but check for spring spacers...

Some times they don't get all of them.
