Has anyone had any experience with wheel spacers? What are they good for, and what are they NOT good for? I have heard some bad stories about them, but can't understand why as there are so many of them being advertised and sold.
My way of thinking is that they are a whole bunch cheaper than buying fatter tires.

Spacers as fitted between rim and hubs are NOT legal in W.A. Dont know about other states.
As such you would void any insurance etc

I doubt it would void insurance unless it was shown to have caused the accident.

A bit like being drunk in an accident that was not your fault. You would be at the mercy of the insurance company who could well void your insurance. As I understand "cause" is not important if you have an illegally modified vehicle and they choose to notice it.

ross,
it would be banned because it is an alteration to the vehicle specifications that are NOT fitted on the vehicle when manufactured and therefore NOT specified on the insurance policy as fitted to the vehicle.

It will also add more pressure to the wheel bearings as the wheel is offset away from the bearing.
My rims are offset, they are also noted on my insurance policy :)

I never said they were legal.I have had a few claims over the years and never been knocked back on illegal modifications and no one has ever climbed under there to see if I had wheel spacers.

Offset rims put the same pressure on wheel bearings as spacers id it widens the track by the same amount

They are also a good way of getting your insurance policy nullified!

The only use that I could think of, is to space the spare away from the back door.

Yeah but a bit heavy if you have the 50mm Ha Ha

I agree with you .
the vehicle is unroadworthy if they are fitted .

If you want to widen the track of your vehicle you can also get rims with a more positive(?) offset.
I imagine a lot of the V8 78/79 series have them fitted

I thought about doing that when tossing up wheel and tyre combinations recently. Since I have never had a tram tracking problem the idea soon went out of my head. Also having different wheels front and back and the possible need for two different spares would be against the KISS principle. Still, I wonder if anyone has really done it.

Why would you have 2 different wheels with spacers??

John,
The correct rim ensures that the upward force is midway between the inner and outer wheel bearing and hence no rotational torque. Spacers destroy this symmetry and can cause bearing failure or breakages.

The small gain in track seems to me to be not worth upsetting the mechanical stability and the insurance cover.

yes, the small gain is not much when measured in cms, but it definitely does make a huge difference to the drivability of the vehicle

Thanks everyone,

I guess it would be better to pay the extra for the fatter tires and rims. What is a positive offset rim? can anyone send me a picture of one?

Hi John

I use wheel spacers all the time depending which wheel set I have on.

I had some made up out of aluminium plate 6mm thick such that 1 or 2 can be used.

First wheel offset - postive is such that wheel rim is moved inwards towards the engine giving overall less track.

Most standard wheels have something like +10 mm , whereas aftermarket wheels are often 0 offset if alloy with some common wheels up to -22mm.

Reasons for use - my main reason is that some of my wheel rims just touch the brake calipers and a 6mm plate spaces them out.
THis also allows big tyres to be positioned inside wheel arch for better clearance.


(Funny story - once got a set of rims/tyres delivered late at night for big trip next day - out them on in dark and next morning rushed around getting up jumped in car and it would not move - stalled everytime I let clutch out - spent long time trying to sort out what must have been a jammed on handbrake - only to find wheel rims were jammed to calipers and had to change wheel set back - talk about dumb.)

Other - Reasons , many of our newer cars have poor rollover stability and widening the track with makes them a little better - espically if the owner has
rasied the suspension on an already low stability car.


Others of our new cars - like some cruisers have back wheel track narrower than front - not by a few mm but by around 100mm - this is bads news and makes car face a lot more rolling resistance, as well as being twitchy.
Wheel spacers of up to 50mm are around to fix this.

In my 4 wheels sets , I have differing offsets and spacers are sometimes used to mix/match wheels and tyres.

2 of my spacers - have been lost to friends who do also use them as shaker says ,to move rear wheel away from door.

A non- approved use is that my wife grabs a spare spacer I carry and puts it on our little stove to space saucepan away from hot gas.

Illegal in NSW too, would imagine all states would be the same, instant defect too.
They can also lead to broken wheel studs as well as the already mentioned wheel bearings.

Are illegal Nationwide Can be used off road but definitely not on road.

Just because you can buy something doesnt mean you can use it anywhere you like.

Off road on private land, or an organised event only.
RWC laws apply to all gazetted tracks.

I thought the risk would be on the wheel studs and would increase the potential for the studs to break.
Also less thread.

When I had my VDJ79 Trayback I had a pair of Snake Racing's 50mm spacers on the back to make the wheel track the same as the front axle.

I was aware of, but wasn't bothered about, all the legal and wheel hub stress issues.

What bothered me most, however, was the combination of basic human laziness and the fact that the nuts holding the spacers on could not be checked for tightness unless the wheel was removed.

That was a pain in the proverbial and was unlikely to be a regular thing. So they became a source of worry and that was an even bigger pita.

I'm glad I ain't too scared to be lazy

Does anybody know if wheel spacers can be used on trailers. Reason I ask is my trailer has 70 series offset and if I wanted to put IFS wheels to suit 100 series, can i use wheel spacers to make up the difference?
Regards
