I think my wheel(s) are bent on my type r, they are ADR 17" with low pro tires, i bough it that way. I did not notice it until i get on the freeway and stayed at above 60mph, its shakes pretty bad, but drives striaight. is that most likely the wheel(s) being bent, or is that my suspension? i moved my front wheels to the back and that seemed to calm it down it a little, that is why i thinks its my wheels not my suspension, but i am not sure.
Now to the second part in 1-3 gear when i pull the motor to above 7,700 rpms the car shakes really bad, whould that be the wheels as well or would that be the motor, or something that has to do with the motor? Any help would be great. And if anyone knows where i can buy a set of stock type r wheels let me know. Thanks for any help.

 

it could be the offset of your rims. it could also be a bent rims or a crack on the rims. usually you could tell that your rims are bent just looking at them, but the only way to find out if the rims are cracked you would have to take the tires off and clean some of the junk off. then look at them very carefully.

 

have your wheels balanced. unbalanced wheels will shake the steering wheel at highway speeds. u wont feel anything when city driving. I used to work at a tire shop. Had a couple of these problems come in.
