got a coupe and i had gt3s on it got rid of them and put on some meshes and now i have a vibration when going 60 and over thought the wheels could be unbalanced so i took it to honda to get them balance but i still have a vibration any thoughts on wat it could be the whole car vibrates its not just the steering wheel and the only time it dose it is when going 60 and over
thanks for any help

 

How sure are you it didnt do it before the wheel swap?

 

Alignment?

 

if it began with the new rims/tires, they have to be involved.
bent rim?
flatspot on tire?

 

This happened to me once cause of my motor mount. Check em out.

 

get the wheels rebalanced
get them checked out if they are bent
go to an alignment shop and have them align it
look underneath the car to check out for broken/worn parts
