Car bounces left to right on highway !?!?!
I just took my car out last nite on the highway for the first time and after 65mph my car was losing control... it was bouncing left to right . I have Tein S-tech springs with OEM shocks and a staggered 18inch setup ..also just got a wheel alignment with some negative camber to UK specs .... Can it be the alignment ? springs ? shocks? This car is no fun if i can't go over 70mph lol HELP

Shocks wouldn't produce a side to side movement on a typical highway, but to even begin to guess what might be causing your problem, I need to understand the symptom(s) a little better.
When you say "bouncing," do you mean that the car is actually moving up and down, or do you mean that it is "bouncing side to side?"
Is this happening over bumps? Over rain grooves? Knowning *when* it happens might help us figure out the cause. Is it at a particular speed, or all speeds? Does it happen when going in a straight line, or when cornering (or both)?
What size wheels and tires do you have?
What tire pressure(s) are you running?
Can you post the final alignemnt numbers?
Do you know what the spring rates are? How much do they drop the car? Unless they are radically different than the OEM springs they're not going to hurt the Showa Spec Coil Overs that come on the car.
If you can give us a few more details, somebody might be able to come up with some suggestions, but I don't want to guess without a little more information.

Orite then... i have 18x8 in front and 18x9 rear Rota D2's ... 225's front and 255's rear ... the car starts the bouncing a little after 60mph and feels like its pulling side to side... i aligned the car with -1 camber in front and -2 rear ...
Also when i go to switch lanes at those speeds it feels like its over reacting ... tire pressure is about 32psi ... what do ya think?

Ive heard that a nice "race" alignment will make your car uncomfortably jolty on the highway, could this be the case?
I'm not familiar with the tires he's running, but some tires will "nibble" on rain groves, jerking the car back and forth.
A good alignment man who's familar with the car should be able to diagnose the problem after taking the car for a drive, but it's tough trying to figure out exactly what the car is doing based on written descriptions. I'd still like to see the final alignment specs, especially toe.
