I think you may need a chance to step back and ensure everything is right.

Check the torque spec on all alignment related hardware.
Set tire PSI to 35psi at all 4 corners, (this is entirely just to rule the tires out so you can get some of the underpinnings right.)
Look over the coilover install instructions from Tein. Are your lower mounts set correctly? I had a set come to me where the height appeared to of been set by using the preload, (slammed,) and the lower mounts were up as high as they could go. Spinning the coilover back down into the mount to Tein's specs and checking preload resolved a very harsh feeling everywhere, (this was on Flex Z's, felt like bumpstops on tiny bumps...it most likely was.)

What tires are you running? What's their condition? If you're asking too much of junky all seasons, or have 'tired' old tires, you could be down on grip which is making the tc light flicker at you and upsetting concentration and the car as well.

I think the folks suggesting some actual data are correct, that there's a bit of proving everything is okay, but you should do all you can to rule out a mechanical issue, and incorrect installation is a common issue with coilovers, be it noise or handling/compliance issues.
