When i reach 70-80 mph range, the steering wheel shakes really bad, and the car vibrates.
At first I thought it was one of my wheels being off balanced, so i had them all balanced... but it didn't fix the problem.
What else could cause the shaking? I definately know it's coming from a wheel, because it gets worse and higher frequency the higher speed i go.
What else could be wrong? Bent rim? Bubbled on the tire? I did a visual check and it doesn't seem to be any of those.. and when the re-balanced the tires, wouldn't they have noticed that?
Could a warped rotor cause that vibration? I know i have a warped rotor.. but I'm not too sure it would cause a driving problem (other then braking funny, of course).
All this started after I put on the OZ F1's from the 99 oz edition eclipse.

Mine was also shaking between 75 and 80. I just replaced my tires yesterday and the problem was solved. My new tires are awesome and really improved the handling of my car. There was also no noticeable problems with the other tires, but they were the problem.

Same thing happened to me when I got my enkei shoguns on and balanced -shook like crazy, and I know for a fact my alignment was fine. I took it back to the tire shop after a couple days, and had it balanced again. the ride was perfect after that.
they said that they were going to do a different "special balance for aftermarket/racing rims." I was thinking to myself whatever, I don't really think there is such a thing. A balance is a balance. I think what happens is someone who doesn't run the machine correctly is doing something wrong. get 'em to do it again.
If you are not on the brakes then the rotors will not make the steering wheel shake like that, even if they are slightly warped. They don't have enough rotational inertia to shake the wheel at freeway speeds. But to test it, see if the shaking gets worse when you press on the brakes.

that's not true. there are different ways of balancing. one (the one they prolly did first) is called static balancing. they use sticky weights and place them in the center. this is the most inaccurate type of balance. static balancing averages the inside and outside inbalance and tells you how much to add in teh center. the accurate and real form of balancing is called dynamic balancing. that's where the balance each side individually. that's what you hae now i can guarantee it. there's no way you are more comfortable with a static balance than with a dynamic

Thats weird bro... my car never shook with those wheels/tires on my car. Id have to say something is out of balance, whenever ive had a vibration problem like that its always either been a bad tire or balancing. The rotors wouldnt do that unless you were braking. I hope you get it figured out.. lemme know how it turns out.

I think its one of your front tires. Usually if the wheel is off balance, it will start shaking around 55-65 mph, and kinda get better or stop when you go faster. You said it starts off light then gets worse by going faster, so i think you might have a busted steel belt in the tire, or a small bubble in the tread. The guys balancing the tire should be able to see a small bubble in the tread when balancing..It could be just your balance is off, but its def one or the other...

yeah, i think all eclipse owners who mod their suspension and wheels go through this problem. i had the samething happen to me adn still does. around 70-90 mph it shakes, but before 70 and after 90 it is smooth again. i don't understand how going faster will smooth out the ride. but anyways, i read in a previous post that adding a upper strut tower bar will reduce the shaking. i plan on getting front and rear soon. later

shuwa29, wow, that's like the same thing that happens to me. after 80, the shaking actually lessens... hmm.. hopefully one of us will figure out a solution.
And fasterGS, i'm guessing that UPS was a little rough with the tire and messed something up. Hopefully it's nothing more then me needing to rebalance it, but it's definately not something i'd blame you for. =)
I'll see what's up after i put my shocks/springs and nuespeed strut bar on.
