Lug bolts or lug nuts - specs for OEM wheels.

There is a spacer that adds another 12 mm or so to the rear offset.



Since I am going back to stock 17" wheels it was built back in 2003, I need to ensure my bolts will work.

All the bolts I see on the car are ball style.

Front most likely will fit no problem.

Rear - they will also fit, but could it be they are too long?



Now they are definitely longer than the front ones.



I guess, in the end the question is - what is the correct length of the OEM bolts for OEM wheels?

The 17's do not need any spacers in the back, or front.

Fronts will have about 7-8 turns before getting tight.

Rear - a few more...



So what do we do?

If you have spacers, the bolts are aftermarket and lengthened to accommodate the added width of the spacer. Just subtract the width of the spacer from the length of the bolt and you have your answer.

BTW, make sure you buy bolts with freely rotating necks. You will trash (and potentially structurally damage) the wheel of you don't)

I have my old bolts from when I installed spacers a few years ago. They're not in great shape but I could cherry pick the better ones for you if you're interested.
