    ok so. you have oem hubs that has lasted.. what? 25+ years? i have never heard of one failing. lets say the new billet hubs have 1/2 - 1/4 the life span? thats 6+ years minimum.. 50 000ks+

    the OE stuff is intentionally over built. i have heard of many bearing failures in 86s. but never an actual hub. if its a reputable manufacturer like Huw says, i dont see the problem.

    ALMOST any car these end up on is going to see semi limited road use.

    P.S im kinda keen. depending on timing.

    Kind of what I was getting at, but I tend to waffle on abit Huw is not talking about some sweatshop melting cola cans into faux rice gear to flog on e-bay. You're spot on Slydar OEM parts are over-engineered (Safety Factor like 5) Race components are tailored to a specific application and optimized (S.F. maybe less than 2 or 1 for non-critical components) But we're not shaving every gram for 1/1000 sec advantage, so there's no reason why these hubs would not be sturdy enough to use on road or last on car for X kms (with +track -mass) provided material selection and the hub itself is engineered with some forethought. I have confidence in these blokes.

    you want me to list over 3/4 of the components ?
    you will have to do some reading to figure this out, im sure google can be your pal for an hour or so

    In regards to the airplane vs car hub discussion I might have something usefull to add.
    I think a distinction has to be made not only between the actual axis that see load on for example a planes wing or a car hub but also on the characteristics of the load. Does the material see tension, compression or shear (or any combination of that). I've briefly worked at an airplane manufacturer and I can remember that when they're determining what material they're going to use where the charateristics of the load vs the material properties are taken into account as some materials are better suited for tension then compression etc...

    Ok chicken littles listen up. Group 4 fabrications say that no periodic replacement is required with their alloy hubs, ever. Id suggest that this was the case with these aussie made ones too if they make them from a durable grade of alloy.

    Sorry but I actually emailed them and asked the question outright, I didnt mean to upset the constant stream of misinformation and opinion that is hampering this thread from actually being informed.

    Carry on.

    Oh btw, if alloy could not be a suitable material from a safety point of view, then nobody told Mercedes when they built the new sls gullwing, maybe someone should email them and tell them they fucked up. No need to explain why.

    That's was exactly my point i was getting at when comparing this to aircraft engineering.
    Like I said 63 ton of air mobile, and nearly 50 ton will be hi grade duralium .
    Thats good enough for me, or how about Nearly 30,000 lbs of thrust trying to rip the wing off ... Hmm

    Yeah they're all valid points aluminium is an awesome material, no doubt. But the engineering requirements in an aircraft wing compared to those in a spindle type automotive hub could not be more different. You cant just say a 737 wing holds 15,000 lbs thrust so I'm going to remake my hubs in aluminium.

    That's each, so just under 60,000 lbs.
    I'm not saying that just because this is made from a certain material then make this out of it aswell.
    But it is sheer testimate to how strong and durable the material actually is and the forces it can withstand.
    And as littleredspirit has shown, others also think it's up to the task.

    i think its a good material for a hub. the steel is just cheaper. a little more material thinkness around the studs and inner bearing race and it should be fine and still much lighter. almost every bicycle/motorcycle hub in the world is made from aluminium alloy. the only specific difference i can think of really is the extra heat cycling from the brakes.

    i would love to hear discussion otherwise, if there is any though.
