Wheels spacers....does it matter?

[rip]

really it depends on you,

It depends if your hubs and rims are both hubcentric, this mean the hub center boss locates the wheel.

Now there is a second, more common way to locate the wheel onto the hub, it's call lug centric. This means that the wheel centers itself about the lug nuts.

Also realize that there are rims and wheel that are both.

Also know that some people swear that if your car is hub centric and you don't use hubcentric stuff (spacers, hub rings, wheel) that you'll get virbrations at faster speeds. Some say that you won't.

So the second type of spacer you shown are hub centric thus really only work if your hubs are also hub centric. With a spacer like the first one you rely solely on the lug nuts to center the wheel.

Now if I remember right porsche have cup styled lug nuts and a hubcentric ring to center the wheel. So it depends on how picky you are.

I myself, figured that the OEM engineered it for a reason thus, kept the hubcentric stuff.
