Hello everybody,

I am thinking of buy new rims for my Xfire cab. 06'

Right now the rims are ( Offset )ET35 in front and ET22 in back. Those are the standard sizes.

I have found some amazing rims, replicas of the SLR Mercedes, check picture.
(rims in the internet Option M443 8x18 5/112 ET35 Nav 66.6 )

But the thing is that they are both ET35.

Do I need some spacers? WHat brand of spacers do you use?
And how is it possible that I hear people say they have different size of ET numbers?
