So I bought vossen 20" rims for my g37 and then added on Eibach springs with a rear camber kit around 7 days ago. Today I was driving around 70 mph for the fist time with my new rims and my car was vibrating! I have the alignment report and only the front right tire has - 1.7% camber and everything else was perfect with the alignment. So I was wondering if that's how the ride will be with the new rims and springs at high speeds or is it because of the negative camber on the front right tire or is it something else? Please help me out here.

 

You should not have any additional vibrations with the hardware you added to your ride. Maybe your balance is off? Since you are feeling the issue at or above 70mph, try a road-force balance and see if that gets rid of it.

Forgot to ask, how are your tires? The reason why I ask this is because I had some crappy tires on my car when I bought it, and used to have that same problem. Anything above ~60mph caused a vibration that made me feel not safe, which is why I never drove the car above 105. I had the balance checked and re-checked to no avail. Well, my rear tires needed to be replaced so I went with all four. Problem solved. No vibrations at all, and I took the car to 125 for the first time and did not realize I got there, because there was no vibrations AT ALL. I love my car again!

 

I don't know man! But it is vibrating. By the way I don't know if this has any effect but my rear tire size is 285 and 245 in the front

 

Tire size should be at 245/35/20 & 285/30/20 also please make sure you are getting a high speed road force balance. More than likely its balancing.

 

Tires are BRAND NEW! Nitto! I will get a balance next I guess. But you really think its that?

 

It could be, it sounds like it is. Did you have everything installed the same day?

 

No! I had the rims installed then after 2 weeks without driving my car I installed the springs and 3 days after that had the camber kit installed.

 

Boom your problem is Nitto!! **** for Tires!

 

I doubt it's the tires! A TON of people have Nittos on the forum and this hasn't happened to anyone. I will get my balance done soon and hopefully that is the problem.

 

Are you using the hub rings on the wheels? Double check your lug nuts too.

 

I got a solution, After putting on my Stance Evolutions on 20x9.5-20x10.5 noticed vibrations afrer 70... went to a shop they re-balanced them and said hey! You need Hub rings...thats whats causing it...well $30 bucks and ran 70+ and vibration gone...the hubs did the ticket...well atleast on mine...

 

Okay so isn't good but I don't know what hub rings are. Are they just any ordinary lug nuts? Or special order? And can lug nuts really make that big of a difference?

 

Hub rings are to make the wheels hubcentric aka fit properly on your car. If the hub size on the wheel compared to the car are just a teeny bit off, it will cause issues like vibrations.

 

Vossen should've provided the hub rings to start with.... I don't know why they didn't if they know our bore sizes are different.

First, you should take off one of your wheels and check the bore of the wheel and see if there is a ring inside. It should be a different color than your wheel. My hub rings were purple, and then I got another shipment that was dark blue. They can also be clear as well.

Be sure to check that before getting anything extra.

 

Well I bought my wheels used to that's probably why I didn't get mine maybe. Ill check though.
