howdy,
When im going between 65 and 85 the whooole car vibrates pretty bad... it gets worse at 78-80km/h... I just changed my stock Z rims to 17's i bought ... Does anyone know whats causing this?
do i need an alignment? or wheel balancing? all help is appreciated cheers.
Wheel balancing would be a good place to start. I had a wheel hub assembly that was bad and caused a vibration at 55-65 mph.
If you just got the tires mounted, they should re-check the balancing for free. I paid $65 each for wheel hubs. (replaced both).

most likely your wheels are not balanced.. balance them if it doesnt help get an alignment.
