New Wheels - OZ Alleggeritas in black

I am totally with you on your points. Autox is a completely different animal.
The thing that gets me with these wheels is that I'm not sure where their proper usage would be.
They're probably too light for the street and will bend easily. Being unrepairable, they're disposable. I'm not saying you couldn't drive them on the street, but chances are you'll hit a pothole and it'll be done. I have a set of 19" cargraphics on my car now (crazy heavy but built like a tank) and I've managed to get a bend or two on the inside lip of those. And I'm realllllly careful.
In the same breath, their weight would fantastic on the track, but will they hold up to the rigors of track use?
I have to "assume" OZ would not put them in the "Racing" category if they weren't confident in the strength of the wheel. I just don't know enough about this HLT process... However, as someone mentioned here I believe... Aren't Porsche wheels cast? People run those all day long without giving it a second thought.

From what I read on their website, it sounds like they use casting to make wheels that look like race wheels and forging for wheels that will go on the track. This is obviously subjective...
From OZ's site:
The single piece philosophy produced with very modern technologies, but followed with the attention dedicated to a craft made product, makes it possible to apply the same qualitative plus of the Formula 1 wheels also in the wheels being mounted on our vehicles: in OZ factory the same product lines manufacture the mythical Superturismo both for competition and street use, continuously sharing know-how technologies in racing and in the wheels for the After Market collections.
OZ uses two metal processes: casting and forging. The first is mainly used in the production of After Market vanguard technological solutions characterizing competition wheels (Whatever the hell that means...). Forging follows a basically different production process, which highlights the physical and mechanical features of the alloy, making them suitable for the use in competition, or for high prestige road applications and very high technological standard.
Metals used in the production of light alloy wheels are aluminium and magnesium. They are non-ferrous metals with physical and mechanical features presenting small quantities of binding elements, such as silicon, copper, manganese, zinc, nickel and titanium. OZ wheels are produced by using different aluminium or magnesium alloys; they can be cast or forged according to the kind of market they are projected for.
Usually aluminium alloy wheels are destined to the After Market, either for the car or motorbikemarket. They are for road use. The choice of the aluminium alloy composition is decided accordingto the wheel's features required by the market.
Magnesium alloy wheels, considering their high costs, optimium mechanical characteristics andlightness, are produced exclusively for competition use to supply Formula 1, Rally, Formula 3000,Super Touring Car, Le Mans, IRL and Superbike Teams.

Many of you guys are quick to associate price with quality. Just because a wheel isn't forged does not at all mean it can't be strong as one. I'd put these wheels against any forged wheel twice the cost for strength because I know how OZ makes them. They are extremely proud of their race heritage and will not put their name on a wheel that is not 100% trackworthy.
I would love, love, love to have an inexpensive wheel that is strong enough for track duty. I think that CCW's come pretty close to that goal, for you can buy a set of new wheels for about $2,800. But the adage "light, cheap, strong: pick two" seems to very much apply to the various Porsche wheel offerings. I hope I am wrong as it applies to OZ's Alleggeritas. CCW's are not the lightest, but they do seem to be fairly stout. That that they are $1,000 less (but not $2,000 less) than the BBS, Forgeline, Fikse wheels is seeming testament to either the compromise with weight versus strength and/or a marketing decision by CCW to not overprice their wheels. I do sure wish CCW's were as pretty as Fikses . . .
Just rambling.
<edit> I certainly don't mean to poo-poo the OZ's or the OP's choice in wheels. I have looked at these wheels as possible alternatives for me. I'll compromise on a lot of things just to show up to the race track, but I do worry about compromising on strength. The last thing I want to do is ball up my car and get hurt because I made a poor choice, be it with wheels or a bad passing attempt.
BTW, Damon, do you know what sort of loads (in ft/lbs) that the Alleggeritas are rated for?

They appear to be track worthy, according to both OZ and a GT3 owner that is currently using them.

Agree, would be interested in data.

True enough. OZ has a pretty solid reputation though and the wheel in question is TUV approved. It's my understanding that TUV is much more stringent that DOT.
What was the story behind this failure? Did it come apart as a result of the spoke connection at the carbon or was it the spokes themselves? Dymag has had more than a few incidents with these wheels from what I understand.

Thanks Mike, hopefully I will see you soon, maybe at FDM. I used one of your threads to help me put black 996 seats in my car. Also just dyed rear seats and trim black with surflex. Much better now, was too much cashmere before

Sounds like you've been busy....... we need to plan a mini get-together at FDM soon (maybe sometime next weekend if I can get away for a few hours).
