Yeah i don't think theres a problem with split rims cause all simmons rims are split rims.

I dont see any problem with split rims. I fixed em every day for the last three years. Just saying what the regulations state. Simmon's wheels are da crap, and I dont expect they would fail for any reason other than some form of damage.

I didnt think B45's were split rims, but anyways...........

I reckon you'll probably find that Performance Wheels in Adelaide do a split rim superlite, cause I saw them advertised a fair while ago in a UK mini mag.
Correction - these wheels would be the UK made Superlite brand - just checked out the website.

Refer to my post in the knowledge base. Download the RTA guidelines for modifying light vehicles. This is your bible for what is legal and what is not. simple.

Steel is tougher than aluminium. This means that steel will take the punishment of a NSW road better than aluminum, will last longer. This is the reason that serious 4wds use steel wheels. (also the reason that most suburban only 4wds sold these days have alloy wheels - they never see a rough track!)

Aluminium is lighter than steel - which is why it was used for racing wheels, and eventually they made them for the road.

Magnesium is lighter than aluminium again, but i would definitely not use these wheels on the road. they just won't last. The ones they use on rally cars get thrown away after each event. Seriously.

The Simmons split rim wheels use a steel rim with an alloy centre (most of them anyway).

It was a pleasure ausmini. I'll miss all you misfits and reprobates

and by "tougher", Mecker (mickmini) means that they take more impact forces better
more flexible and resistence to plastic deformation. the kinda 'bounce' back

aluminium and magnesium are much more 'crystalline' so a crack would propagate and spread

you should also NEVER weld wheels back again. the heat generated around the weld will distort the lattice and residual compressive stresses will make a "strong" area next to a "weak" area and that difference will leave a crack between the two

most of you are right from what i know /heard

MB racing wheels are made by a Miglia Racer called Mike Barney and the Spectrum wheels are made by Metal SPinners and are different to the MB wheels both of them are made for Miglia series in UK as they are very light spun alloy rims with alloy centres (3 part wheels )

i have contact phone numbers for both Mike Barney and Joe Butler

email me and i will give you the details

Also Minispeed make a wheel very much the same as the Spectrum which is what i am looking into atm

I just picked up a set of four jelly bean mags (only for the good tyres). Every single wheel is cracked on the spokes!! Don't know if the wheels are a bad design or the car they were off took a serious beating, but I haven't seen so many cracks in my life! Guess the wheels are scrap now, or melt them down for the alloy

Anto - cut them in half down the centre of the rim, paint 'em up all nice like, make them into garage wall clocks, and sell them on ebay

the set of jellybeans I'm selling aren't cracked at all, so yours must have been driven by someone crazier than me!

That's the thing - they were off a stock-as-a-rock 998 Clubman. Maybe the cracks were sustained on a previous car. Still, you'd have to try pretty hard to crack all four of the wheels. I could understand just one, but four?

Anto.

probably corrosion induced cracking if it is on all four. i would describe it but i am off home now...

instead of loads greater than the yield strength (breakage point) to crack the material,
corrosion cracking works along the grains of the metal
usually starts with a small crack, small loads open up that crack and the forces holding the grains together are torn apart by the natural corrosion of the metal
should be many small multi-directional cracks instead of great big linear ones
