I got my wheels a few gays ago, and when I hit 60mph+ the car starts to vibrate a lot. I have had the car balanced twice already and it still does it. What do you huy think I should do? Maybe an allignment? Im running a 19/8.5 with a 38 offset, and a 19/9.5 in the rear with a 45 offset.

 

You might want to try hubcentric rings first. You'll have to check to see if your wheels need them. Most companies create the wheel so that it fits the larger hubs (cheaper for production instead of making custom-sized wheel to fit specific hubs). So, if that's the case, your wheel won't sit flush on the car's hub...causing some vibration. You may want to call the company you got them from and ask them if you need them with the wheel you got.

For your reference. most hub rings have a 73mm outside measurement. For the G35, we need a 66.1mm inside measurement.

 

I already have those on there.

 

I would try getting rid of the gays.

 

LOL . . .

Seriously, an alignment maybe in order and then proceed from there.

 

Have they been "road force" balanced? If not find a larger Infiniti dealer or the like (I use my local Honda dealer) since they have the Hunter 9700 balancer. Here is a link to the balancer: http://www.gsp9700.com/ It's an amazing machine, good luck.

 

Are the wheels new or used? Did you get a balance?

 

You may have a defective tire as well. Not often but it does happen.

 

did they put wheel spacers in that you don't need?
