Running stock chromed wheels. I ordered hubcentric spacers 10mm and 12mm.
Confused on the bolts?
Having a mobile mechanic come out to the house on Wednesday to do the eibach spring install.
Which bolts to order?

Having to order so many I need a second set of eyes here...It's an 05 roadster base.
Thanks all!
Tried calling the vendor. No answer???

I think we have the ball end as far as length, remove a wheel push the factory bolt into the wheel and hold it tight and see how much you have sticking through, then do the same with the spacers on the wheel you are tring to put on. Then you will know if you need longer or shorter lug bolts.

 

Thank you!

 

Just add the spacer thickness to the OEM length and order that length. Remember to get "ball socket" type and not tapered.

10 for the front and 10 for the back.

 

Wish I was brilliantly logical like that....
Perfect thinking. I'll do that and thanks. Everything seems so complicated with these cars. I somehow abandoned the logical thinking path long ago.

 

Okay did some research.
Oem is 12mm x 1.5 bolt----bore is 66.6 factory-hubcentric spacer should be 66.5 for perfect fitment (avoiding any wobble issues) and of course the 5x112 bolt pattern.
So my options are the 12mm by 1.5 or 14mm by 1.5
I would assume the 12mm is the diameter of the bolt and the 1.5 the length???
Or...is the 14mm option indeed the longer bolt.
Daunting task these spacers....
Anyone with this set up have a vendor...

 

12 mm diameter. 1.5 mm is the pitch. (distance thread to thread).

You have to find out how the bolt is measured for length. From the bottom of the ball or the top of the ball. Go from there!
