like the title says my car has a vibration between 50 and 60 mph...thats where its most noticeable...just put on new rear drums and shoes and new front rotors,pads and calipers...both frozen somehow O_o. tires are practically new about 10K miles on them. any ideas what would cause this problem ive read that it could be unbalanced tires which im taking it in on tuesday to have done...ive also read it could be motor mounts or cv joints ? can ANYONE isolate this for me i would appreciate it a lot

 

it's unbalanced wheels. they will probably tell you that it's just that low profile tires react to the ridges in the road more... a balance will take care of you.

 

yep, you need to get your wheels balanced

 

alright i hope its just that cause ive spent enough money on this damn car...i dont understand how both calipers would freeze up..

 

thread jack... mine does it too but has only done it since my wreck... and i just had the wheels balanced today and still does it alignment tomorrow.

 

mine does it too but around any speed.
i am getting my rims off sat and the place i went to said it could be a warped rotor. idk if when i got the rims put on if they used a torque stick or not. ur suppose to.

ill find out if my brakes are messed up when i go on sat.

 

My 09 SS/TC does that a little but only when I get on the throttle at certain speeds. If I let off the throttle, it goes away.

 

check your tires for warps.... could be the steel belts...hit any big pot holes lately??

 

idk i took my rims off today. the guy looked over the rims and he said something about going to gm and asking about pulsation on the rotors.
the vibration stopped.
so its deff sutn with the rims and not my car.
