Just bought a set of 17's, with 205-40-17. I'm getting a slight vibration. There balanced. Is there a kit i can buy to help out with this?

 

are they seated correctly on the hub? if they're slightly off, then you'll feel a vibration.

and what side or part of the car is vibrating?
what speed is the vibration starting/stopping?
did you install a drop with the wheels? because the alignment can also slightly contribute to any vibration.

 

if the vibration starting from 100km/h, you need "balance" your tires / wheels on tire shop.

 

did you get hub-centric rings?

 

no I did not. I think this is what im told I need.

It is very slight vibration, not to bad. Just noticeable going down the highway. Wheels are balanced.
Also Is there a hardened wheel lug studs out there. I have had 3 break ( originals ).
But just bought new lug nuts I hope this helps. This will be the second time taking that front end apart. 100 miles on that new hub bearing and now i have to do it again. Grr

 

did u buy these wheels used? if so, theres the chance of them being bent. even if they balanced out on the machine, it can cause a small shake/vibration.

OE studs are probably just as high grade as most aftermarket studs. get a tq wrench and tq to 80ft/lbs and you shouldnt have a problem. if u have been driving a lot on a hot day and need to take ur wheels off, let the lug nuts cool to reduce the risk of breaking the stud.

 

i'd get the hub-centric rings then. they're pretty cheap and might help. if they don't help, you only wasted like idk 15 bucks, and you should have them anyway.

Where and what size would I need?

also I just had them balanced, so it is not that.

 

not sure where you would get them. search on google or something. mine came with my rims, so i'm not sure where you would buy them separate.

 

You have to measure your hub and the hub opening in your wheel to know the size. Here's a source that has most sizes:

The shop that sold me my Black Racing Pros did not have the correct size adapter rings, so I had to run without them for a while. The vibration was very noticable on the highway. After they sent me the correct aluminum rings, I found that the vibration was reduced 90%. There is still a small amount, but not nearly as much as without them.
