Hey guys
Quick question. I have 19mm spacer hubs on the rear of my 76 clubby which look fine with 165/70/10 fitted But looking at the front flares I reckon 25mm spacers would bring the wheel out to the limit of the flare for RWC acceptance. Question is Is it ok to have 19mm spacers on the rear and 25mm on the front?
Cheers
Rob M

No reason why not.
Note those 19mm ones are Moke, they are not as common as the 25mm ones, which were used on all Clubbies with 4.5" wheels and drum brakes, also Cooper S & GT (rear).

Correct me if I'm wrong, but I thought spacers are illegal in Australia unless they came from the factory. The spaced drums are OK, but I don't think you can have separate spacers.

I think they are talking about the drums with the built in spacers

The old rule of thumb was. the spacers needed to be screwed on separately to be legal. Not sure if that's still the case.

This spacer issue is again formed in ignorance of the mini.

Most cars have a central protruding chamfer on the hub so the wheel locates centrally on this and the wheel nuts clamp the wheel to the face of the flange and force the wheel around this chamfer centralising the wheel as it's tightened, the Mini's locate the wheel centrally off the wheel nut position, no chamfer used here.

For best balancing of the mini wheel it should be done on the car as the wheel could be off centre by the accuracy of 4 wheel nut holes. Most modern tyre fitters dont have the equipment to do this and separately balance them off the car. So they refit them off centre and the wheel shakes again.

SO the reason spacers are frowned on is they either dont have the chamfer to locate the wheel centrally and/or they aren't mounted to the backing flange and the wheel becomes off center and out of balance. So spacers are not allowed. Assemblies of the hub or wheel are though (so bolt the spacer to either)

Back in the day some racers would recess chamfer the hubs and fit a double ended chamfer ring to perfectly centre the wheels every time. Apparently having a steady wheel is important....go figure!

Good info Besser, thank you. Now for another question on legalities and safety ( not necessarily the same things always) Hopefully Rob Mitch has his answer.. if not apologies thread hijack.....
Fitment of changed PCD rims, it seems there are new fitment with various PCDs able to be ordered, fair enough,, not sure about inhouse quality assurance of centring but ok. but what about retro fitting altered PCDs??

Qld RWC requires wheel track to be no greater than +/-25mm from standard factory wheel track for an independent suspension vehicle and +/- 50mm for a live axle.
If the spacer is designed and install by the factory and is built into the drum or hub as part of the design it is ok. Also if the wheel itself has a spacer cast into (alloy)or welded onto (steel) and does not exceed the above factory figures +/- this is also ok, the 12'' clubman wheels had a steel spacer welded to them from factory.
Also some early Porsche 911's had non fixed spacers from the factory technically legal but what I call a grey area.
This may have changed since I last read the ADR's, but I would be surprised.
Mini/moke wheels are centralised by the chamfer on the wheels and nuts this also hold the nut tight.

The smaller spaced drums were used on mokes and clubman's, if using the smaller spaced drums it is very important to use the correct wheel studs. Don't laugh I have seen plenty that haven't.

As for PCD they must remain as per factory even when brakes or axles are changed so for the mini/moke 4''.
It is possible to have an approved engineer redesign the hub and blue plate it. Or you can have drawings made and send them to Qld transport Brisbane with the correct form and money to be assessed directly.
Also note that normal blue plate inspectors cannot do this approval it must be an engineer.

Many years ago people were fitting Holden etc wheel to the mokes/minis, the PCD was metric, while they fitted to a fashion the studs were bent in the process, this caused wheel wobble issues and wheels coming off due to snapped studs but not as often as you would think.

Hope this helps and my memory is holding up
