Wheel Spacers 101

Trips

Here is a good thread.

Anyone have a setup of 15mm spacers in front and 20 rear?

There are two types

Type 1. Requires you to replace the studs for longer ones some prefer this method but does require more work

Example:



Type 2. Require you to only remove the wheel to bolt the spacer to the existing studs and reuse the original lugs to tighten the wheels to the spacer.
This the easiest way to go.

There is a cost different between the two options

Example



Now the only thing left is to decide on how big of a spacer one uses?


Most will go with

15mm front 20mm rear
20mm front 20mm rear
20mm front 25mm rear

Thanks. That was a very helpful video. He mentions one reason you would want to add spacers is to accomdate larger brake calipers. I noticed the three front rims Nissan offers come with 43, 47 and 40 offsets. I assume that's to accomdate the larger calipers on the front brakes. Does anyone no exactly how much offset is needed to accomodate the 370Z front brakes (non-sport edition)?

Also what if a wheel has more offset than the factory wheel? For example, if I replace the rear factory 18x9 +15 with a 18x9.5 +35. I believe that will increase the scrub radius. What effect is that going to have on tire wear, performance, etc?

Before you flame me: I searched for an hour and can't find a straight answer!

So please, somebody answer this:

Will version 2 bolt-on 15 mm and 20mm spacers work with Factory 18" wheels?

If yes, do I use 15mm on the front or the back?

Does anyone hav experience with factory 18" wheels and bolt-on version 2 spacer combination?

Thanks!

Jordo!

Okay... I don't know the exact answer, but I can tell you that the stud replacement is a sure fire thing -- it WILL be able to fit. With bolt on it's a bit hit or miss depending on your wheels.

I would just ask the seller -- if they get it wrong, you will be returning them, so they have an incentive to shoot you straight before buying...

Does any one have a picture (or take and post one) of the back of the stock 18" wheels? I would like to see if there are recesses where the studs could fit for a flush installation of v2 bolt-on spacers.

Thanks!

Turns out this was a dumb question. I will correct myself with info I learned in another thread for the benefit of anyone reading this thread who doesn't know this.

Offset has nothing to do with brake clearance. Brake clearance is simply a function of wheel design. If you have a wheel that doesn't clear your brake calipers, adding a spacer will always increase brake clearance.

Having said that, here's a question....
Someone told me adding spacers can cause wheel bearing failure. Can anyone confirm or deny this?
