2000 poor handling on uneven roads
My 2000 coupe has very poor handling on even roads, almost to the point of being dangerous. Cannot see anything loose in the front suspension, had the alignment checked/set, still handles bad. Almost like a severe pull. Any common things to check?

Had the same problem on my '01 vert, running old GY run-flats that were a little under 50% tread left. Especially noticable in temps 40 degrees or below. It felt like the steering wheel would jump left or right out of my hands at times, around 35-40 mph.
Replaced with a fresh set of Hankooks and problem went away entirely, plus got rid of all the tire noise.
Check the dates on your tires, old run-flats get hard and 'tramline' in the tire grooves of the poorer roads.

I read something about some cars not having some sort of plug removed from the shocks at the factory which basically made them useless. Look and see if you have a plastic strap sticking out of your shocks where the two pieces meet.
EDIT: seems to be only magnetic ride related

Did they check both front AND rear alignment?

Do the alignment numbers match exactly left to right? The factory tolerances have such a wide range that the shop could have pointed both rear wheels to the left or right and been "within spec" along with using caster and camber numbers that are way out side to side.

SADLY, it gets tougher and tougher to find somebody who can do a proper wheel alignment. Believe me, if I was 20 years younger, I'd be buying my own rack....

Put some tires with rounder sidewalls. You won't believe the improvement. I went from GY Runflats to Michelin Pilot Sport A/S ZPs and it felt like a new car. No more hopping and skipping around corners like an old Pinto.

X1000My old Kuhmo runflats would take me all over the road. It was horrible. I lowered the pressure to 28lbs and it helped a little, but after replacing them, it was night and day.
As others said, under 40 degrees those runflats are like rocks.

I have the same problem......car start to move, but the steering wheel hasn't....its kinda worrisome when you are doing 80mph....
its like the tire is catching the edge of a pavement ridge and yanking me over... I lifted the front and everything seems firm and solid...
I replaced my tires with hankook ventus last year and I still have the same issue... I have never done and alignment since I have had the car (6 years). but it tracks pretty well, and tire wear was even.
I was thinking maybe the drive shafts were working in and out, or something odd.... that didn't show itself in "wear" that you could feel pulling and pushing the tires...
I guess the rear tires play a roll, but it seems like its a loose front end
is it possible( haven't checked yet) that the steering box could get sloppy?
thanks

I used to think , Its just the wide tires grabbing every little defect in the road....
my hankooks were brand new and the car was doing the same thing
my tires are not runflats!
and it is so hard to think its a tire wear issue.....then all cars would display similar traits if they had wide tires..
