Spacers, nuts and bolts? What's stock?

[gerardgt]

Hi there, a couple of questions.

I am looking for the OEM part numbers for the original bolts and nuts.

The previous owner put spacers just on the back and I've been told the nuts had to be changed as well as getting longer bolts.

Now the front wheel bolts and rear wheel bolts are different. What are the stock part numbers? Why the original nuts don't fit?

In paraller, which spacers do you recommend, same size front and rear, with stock suspension and stock 18inch wheels?

Any pics?

Thanks!

Surely you wont want these though if you are then going to add spacers again ?

Why do you want spacers (if indeed you do)? Is it for looks or for a technical reason (wrong offset wheels, clearing bigger calipers, etc.)?

The OE bolts are no good because they're too short to provide enough grip on the thread in the hub...so if you use 5mm spacers you need 5mm longer bolts, if you use 30mm spacer you need 30mm longer bolts.

However, DO NOT use the longer bolts if you remove the spacers as the bolt may go through the back of the hub and create issues with anything it comes into contact behind the hub.
