I noticed for a while that at low speed(5mph), my car seems to wobble. However, at high speed(65+ on the highway), my Z isn't harsher then it normally it and i have no pulling problems, and it handles great. As far as i can tell visually, my rims aren't bent. Any ideas? if the rims were out-of-round, could that explain what i am experiencing?

 

maybe the wheels aren't balanced correctly???

 

Oops, let me clarify, perhaps wobble is a bad choice of words, what i meant to say was my cars feels "bumpy" @ 5mph.. in the up-and-down sense. and at highway speed, it seems fine.

 

re-torque the lugs, and if that doesnt help, get them re-balanced.

 

Does the car set for awhile? You may be getting flat spots in the tires that work themselves out after a few blocks.

 

thanks for all the feedback. FYI, i drive the car daily to work.
The odd part is that my Z performs flawlessly when driving at medium to high speed. alignment is nearly perfect. But somehow at less then 5mph there seems to be a bouncy ride. BTW, my OE tires that came with my Ray's Rims are showing cupping now. :-(
