I'm purchase a set of volk sf challenge from another member here. The problem that I'm having is I'm getting vibration when I'm drive on the freeway. I can feel the vibration start around 70mph, and it vibrates more when I go faster. Anyone know what might be the problems that I'm having?? When I purchase the wheels it came with tires already, so I didn't take it to a wheel shop to installed them. I just swap my old wheel with the volk. Do I need to install Hubcentric Rings for these wheels?? Thankz alot

 

May need to be balanced are they different sizes front and rear?

 

Yes, you need the hub-centric rings.

 

Is the steering wheel shaking or the whole body of the car shaking?

Steering wheel shimmy or shake usually is from out of balance and body shimmy or shaking usually is from no hubcentric rings.

SF Challenge have a centerbore of either 73.1 or 66.1. Your vehicle is 60.1 centerbore so you will need those.

If you purchased new wheels, its always wise to get a rebalance on them when you can.

 

do anyone of you guys know where I can get them and what size should I buy?
