i dont know how this felt b4 when i just bought this car, bcuz i was all happy about it....but time passes by,,,i feel weird about ...

its hard to describe...but i will try my best....

when i accerelate i feel ground is touching my feet...
i did not lower anything,,,

and also when i am stopping, braking, i feel and hear like echoing from ground..

like "Doo,DOO,Doo" its not actual sound from brake or anything,, but its like echoing...and i feel like its unbalanced, so it feels like bouncing..

i dont know its really hard to describe..

so i went to dealership, bcuzi thought that i had problem on my brake..

but they said, my tires are not even so that is why its doing that

but my tires are pretty much michelin brand new tires...
and i see my tires, it loooks fine to me
dealership asked me to change tires, but i cant believe them..

is there anybody has kinda same feeling as me, or anybody know what it causes to that..???

in other, wheneven i accelerate or brake, i feel like bouncing slippering with echoing from the ground..like "DOO DOO DOO DOO......."

hm..help me out

thanks

 

look man, I think English is not your first language, but I have no clue what you are saying. you should spend a little more time rewording your post and describing the problem if you expect anyone to be able to understand enough to help you.

g/l

 

it sounds like you're describing the uneven treads on your tires; that's what would make that "DOO DOO DOO" sound. doesn't matter if you'r etires are new, they can still be defective.

 

I sure hope English is not your first language. If it is not I apologize. If it is go back to school.

 

new tires and an alignment.

 

sounds like negative camber/tire feathering/alignment issue that most G coupes are having...
would suggest 1st do alignment see if sound still exist
if it does..afraid gotta change tires
how many miles on tires?
