Rear hub spacers

[Stiv]

Hi guys,

Can someone explain to me why are rear wheels more inside the car than the front two?
And what will rear hub spacers change regarding driving characteristics?

Thank you :redface:

There are a number of theads dedicated to the subject of wheel spacers. Go to the search feature at the upper right of the page and type in "wheel spacers". You'll find quite a bit of info then.

I've been told the car has a narrower track in the rear.

Rear hub spacers, or wheels spacers (that go on the outside) do this:

1. Widen the track on the wheels they are used on. This can improve handling in corners and overal stability (resistance to cross wind, for example).

2. They bring the wheels out for a more flush look, which most people think improves the overall look of the vehicle.

what's the advantage of hub spacers over wheel spacers?

hub spacers are a hassle free part. you never have to mess with them once they're installed.

wheel spacers require the use of longer studs $$$ and will put more wear/tear on your wheelbearings in the rear than hub spacers (which put no wear/tear at all on your bearings)

Ok, but why is that so? The only thing I can think off is that this way puts more force on the outer front wheel during cornering (e.g. better traction). For example, imagine a car with two front wheels and one in the back in the center. The force distribution would be much different.

Or maybe I misunderstood something, maybe it's my bad english :)

I've seen this statement made a few times and would like some clarification on a question which always goes through my mind. I have 10mm wheel spacers with ET42 wheels. How does this combination differ, as far as stress, from a ET32 wheel by itself?

i believe the the spacer goes behind the bearing rather than front.. front will extends the distance between the wheel bearing and the wheel which cause more stress on the bearing due to leverage..where as behind keeps it the same a stock just sticking out more vs stock.

Does not answer my question.

The way the body is designed they appear not to be flush with the fenders. But the wheels are evenly spaced. If you would take a string and run it from the front tire to the back you would see there is no angle change. Spacing out the rear tires brings the tire out to bring it more flush with the fenders to correct the cosmetic issue while providing a wider rear track. Wider means more stable. Vehicle will handle better especially on turns. Same reason why putting high offset wheels on your car it handles better.

Also the way that the spacers are installed they dont put any unessisary stress on the bearings because the bolt inbetween the hub and the rear axle assembly.

The type of spacers that go on the outer portion of hubs and with extended studs are the ones you have to worry about because over time they may cause premature bearing failure. But if your going to hit pothole with enough force to damage a bearing its not going to make a difference what type of spacer you are running.

It doesn't.

Race teams around the world use wheels spacers (to clear larger brake calipers, for example). I have used them for years.

Anyone claiming extra stress on the wheel bearing is sharing "book knowledge" -- sounds right, but there isn't much evidence that damage occurs BECAUSE of the spacers.

With that said, maybe there is a longevity problem, that the bearings won't last 250,000 miles.

It doesn't.

Thank you. :thumbsup:
