the 10mm spacers and even 5mm spacers come with new longer hub bolts...

that is when purchased from company's like Eibach or H&R...

Eibach is the only company I am aware of with 10mm spacers with the hub centric wheel bore part...

H&R and Eibach both have this on their 15mm, 20mm, 25mm...

I should have made that more clear I guess... Just figured since it comes with them it would be understood...

And personally, if you are going to use a 3mm spacer, that is giving up half the threads that are catching on your lug nuts anyway... I couldnt do that! Get longer hub bolts!

 

I wouldn't use 3mm spacers. Go with 5mm Hubcentric spacers to be on the safe side. Ichiba makes great aluminum spacers starting at 5mm's. You can find a set on ebay for $59.00. Longer hub bolts included!

 

H&R, Eibach, Ichiba etc... they make "Hub Centric" 5mm spacers, but they are only hubcentric to the wheel hub... they do not have the "Hub Centric" extended part that goes into the wheel bore...

This is the type of spacer the 5mm are...


This is what the 10mm and larger are like... with the hubcentric extension to make the wheel hubcentric to the spacer which is hubcentric to the wheel hub...
