Wheel Failure - Scary Time...

Yep. Too much style & not enough substance.
I wonder how many wheel designers are engineers & how many are graphic artists?
OZ are a decent manufacturer and provide a lot of alloys for motorsport including Touring Cars and F1.I wonder how many wheel designers are engineers & how many are graphic artists?
Multispoke alloys have been used in BTCC for ages.
Thanks for the vast amount of replies.
These are a set of genuine Mitsubishi wheels which were fitted to homologate the wheel for use in rallying
From the factory, the centre caps read O.Z, as shown here, but the wheels are actually manufactured by Enkei and are stamped so on the rear face.
I had them powdercoated in this colour.
I will photograph the other wheels upon work finish, and post for discussion
Thanks again, Tommy.

Did you actually buy them yourself though?
The reason I linked to the other thread was the fakes come with all correct stamps and hallmarks making them nigh on impossible to tell apart until this happens. The fact all four are doing it especially the rears rule out the type of tyres used.
If you did buy them yourself it may be worthwhile getting them inspected by OZ to ascertain if genuine or not. If they are I would say you may have a good argument for a new set on goodwill. If not genuine it would be in their interest in assisting you in following the paper trail back to where they came from.
Good luck and look forward to seeing the other pictures.

Not posted on here for a couple of years, but I thought I'd make you aware of my experience so that somebody in the future could possibly avoid this.
I have a Mitsubishi Evolution VI GSR running around 300hp and was on a spirited drive. As I turned, quite sharply into a large roundabout, this occured, with no impact or collision.
To note, these are genuine wheels!
Any clues as to their failure?
All the other wheels are similarly cracking in the same place, too.

Flippinheck! When radials first made inroads into sports car racing & bitumen rallying, Morgans, MG A & B & Triumphs started breaking wheels & stub axles.
When we advised Morgan of the problems we were having in Oz with stub axles, it took them less than 6 weeks to have heavier ones available.
At the time regulations called for the original center to be used, but they dropped that pretty quickly.

I'm 50/50 if I should approach Mitsubishi about it? They might just laugh me off?
Might be an option.However I cannot recall those wheels actually fitted to any "official" Evo back then.
From memory the Enkei used back then were either 5 spoke or 12 spoke for tarmac only...
And moreover I can't remember that a car manufacturer has to homologate the wheel for rally use.

Strictly correct, but in a practical engineering sense if your non ferrous components can get to 10-20 million cycles without failure you can treat it as a you would a limit on a iron component. As in it's so far away from the number of cycles a component will see in the real world that it may as well be a limit.
20 million cycles in terms of a road wheel doesn't seem to be very much. Given a 2 meter tyre circumference that is only about 25000 miles, and that's cyclic stress just from the cars weight, let alone bumps, potholes and cornering forces.AlexIT said:

These are the wheels that all Evolution VI GSR's left the factory with. They were badged and stickered up as OZ, but were manufactured by Enkei and Stamped Mitsubishi on the reverse.However I cannot recall those wheels actually fitted to any "official" Evo back then.

They used to look like this before I went wild with the paint pot...
These are the wheel which this car came from the factory with
If they are the original wheels the car came with could ask Mitsubishi but then its an old car now and they could say they are simply at the end of their expected lifespan and if the car had been to dealership and a crack spotted they would have said new set required, just like when any other part wears out.
Infact no point asking, its what 12 or 13 years old? Past scrappage time for many vehicles

This will have weakened the metal and caused the fatigue.All the other wheels are cracking because they went through the same process, I remember a thread a month or two back with countless stories of powder coating causing failures like this in its early days.
