more likely an alignment/wheel issue.

Is it on aftermarket rims? what brand?
How much is left on the rubber? is there uneven treadware?
Are there any bubbles or noticably large scrapes on the side walls?
do u feel anything coasting down a hill

alignment?

if its always shaky but gets worse the faster you go, it probably means you have warped wheels or your tires have uneven wear.
right now, one of my right rear control arms also have worn bushings. it doesn't feel shaky but it's causing the car to steer left and right slightly and it feels like the steering's loose. go under the car and try shaking the suspension rods, if they're loose then the bushings definitely need to be replaced. i have the parts already to fix mine, but i'm just waiting for my tank to go empty. i'm not really looking forward to having to drop the tank and also removing those long bolts holding both rear arms..

thats anything on suspension, bad tires, balancing, alignment. if it was on idle then that would be a mount.

Well it gets real bad at around 70 but it could be my tires they look put on oddly also maybe the cheap rims on there ill check that out anybody recommend coilovers for the st185 for a decent price?
