shaking problems

[jayspeedy24]

i've had my gts dropped on tein s.techs for about 3 months now and i've got a problem..im overseas right now so i dont know how legit it is or not..the wifey is driving it..but anyways..shes saying that its still shaking when she goes above 70mph and its already been aligned..any ideas on what could still cause it? should i go ahead and purchase endlinks or get the eibach camber adjustments?? i'll be back home in 3 weeks(yea!!) so i'd like to know what to buy now so i can have the part at home ready to be installed..thanks.

I'll wager money on bent wheel. Put it to you like this: your car is lowered, which means it has virtually no compression travel left on the stock shocks. Wives don't pay attention to things like potholes. I'll be she plowed into something and bent a wheel.

You might need to get the tires balanced or you maybe need hub rings. Or like mentioned you might have a bent rim or a dead spot on one of your tires.

im with the bent rim. i have a small bend on the front right rim and ive got the shimmy!

[wacko604]

rotate the tires and try it again

man that sucks..thanks for the help

check for bent rims, then try front tires balance...

yes like said, first, rotate the tires, you might have one badly balanced or damaged.

But also, check the tire pressure. I have BFG KDW2 now and didnt like hem at all in curves at first. Iwas using same tire pressure as before (34 front -32 rear) and tried different pressure and still, the car was handling like crap compared to before w/ t1-s. I had stering vibrations too at 70 mph and more. I finally increased the tire pressure to 'bout 35-36 and handling was so much better. Like before again. I dont drive my car now (tranny issue) but from what I remenbered, steering vibration looked gone but the tires are much more noisy which I dont care, it is resonable. I hope it is gone when I ride the car again! BTW, now, I finally feel like the kdw2 is a nice tire. maybe very slightly less stable in curves than t1-s but w/ better str8 line reaction. No wheel hop or anything like that compared to my old t1-s. Well, so far I'd say they are perfect for my driving ..

By changing suspension setup, you might affect the balance, thus affecting the needed tire pressure. Hope it solves your problem! I knew the tire pressure has an impact before but I never knew it could make that much of a difference! In my case, it probably had to do with the tire threads ..

Someting else to look at if the balance, rotation and wheel check doesn't pan out, check your coils. Make sure they are seated correctly. Also, one of the most over looked cause of front end shimmy is a brake caliper slowly locking up.

thanks for all the advice...right before i left..about a 1 month..i got my springs put in..i had about 29k on the stock springs/struts and i've read that the stocks struts are okay since the tein s.techs dont do a drop more than 2 inches..i hope thats what you guys heard as well..but the stupid thing i didnt do was get them aligned right after...the place i got them installed at said i should be good for a while...i kept telling the wife to get it aligned and she kept blowin it off...but what am i looking for when you say the brake caliper is locking up? will it look like its randomly touching the disc? kinda like lopesided? hopefully when i get back it isnt as bad as she makes it sound..

Haha. You heard wrong. At 29k miles, you're stock shocks are on their way to dead. Lowering the car at all makes them die fast. My stock shocks on Progress (1.75" drop) springs went to hell in like 6 months, and that was on a car with 3k miles on it.
