hi Guys 
i just fitted new semi slick on and the wheel shop cant fix vibration after 110KPH. and they are saying its because of the wheels are not for mr2 and may need  some O ring or somthing.
110k and under is very smooth.
 
any idea guy. or anyone has the same wheel on mr2

What they may be talking about is a ring that goes inside the wheel so it seats on the hub. I believe they are called hub centric rings. I believe they also shift the weight off the studs and onto the hub.

i just googled Hub Centric  Rings. and i understand it now. i just wonder did any one had to do it on their mr2 with same wheels.
thanks 123 Grosso 

I'm sure you wouldnt be the first person to do it. Some people swear by them and others dont see the point, they're relatively inexpensive and if you are going to be doing those speeds often then they would be worth the investment.

well im preparing the car for track use only. so i may need them

I had GTR/GTS-T rims on my Bathurst… and yes, you should definitely be using hubcentric rings to prevent them wobbling at higher speeds. Aluminium ones are preferable, though you can also get plastic ones.
 
These are exactly what you need (the correct diameter for R32 GTR/GTS-T rims):

sorry guy im a little worried now. i got the hubcentric rings 
i told do not use them as its dangers on high speed specially my car going to be track days car.
as it could brake the studs. is that true. 
any one have hubcentric ring on their wheels and go racing with no problem. 

As I understand it, NOT using hubrings is what puts your studs at risk, because without them, the wheel is no longer located by the hub… so all the pressure is on the studs.
 
If you have any concerns, rings Peter Hennesey at Road and Race in Rydalmere and ask his opinion. Peter is as knowledgable about wheels and suspension as anyone, prepares race cars and he also races himself.

I think people are confusing hub centric rings and hub centric spacers....
 
Hub Centric Rings align a non-standard rim to the hub of the car so the wheel is centered true and reduces the stress on the studs.

 
Hub Centric Spacers space the wheel out to change the offset and can apply additional loads to the studs. (However they are still a much better thing to use then NON-hub centric spacers).

 
If your wheel shop it telling you not to use hub centric rings, I would go find another place that knows what they are talking about....
