Fox rims - reconditioning stop

  • What is the reason for this higher value?

    Do you know the difference between casting and forging?


    • Casting is cheaper, the aluminum is liquefied and poured into the mold, then finished and painted. Done. This is how >90% of all rims are made.
    • Forging means that the aluminum from which the rim is made is no longer liquefied. Instead, the aluminum blank is placed in a mold and pressed/hammered into the mold by immense pressures, aka "smooshed". This compresses the aluminum considerably as it is pressed together. As a result, the material structure is greatly changed or compressed and the rim becomes much more stable. This also means that less material has to be used, because the rim - designed for the same load - can be constructed more easily. Overall, the better process, but also more costly (tool or mold must be built and wears out over time, other aluminum alloys that are less brittle or, more elastic to survive the forging process etc.... ) and therefore more expensive.

    The Fuchs rims are forged. A Fuchs rim is about 30% lighter with higher strength at the same time....


    Crankshafts, camshafts, etc. are also mostly forged (from steel). Three guesses why...

    The insolvent BBS (not to be confused with above mentioned company) also produces forged wheels for Porsche, but only from 19".


    The Cargraphic wheel is available with forged stars.


    The 1552 also has forged stars. The original Outlaw 001 is a complete forged wheel.


    There are other alternatives. But they are probably not cheaper than a Fuchs wheel.

  • However, forging only works with fresh dies and a press in mint condition. This seems to be no longer so great in Meinerzhagen, if you see the Easter eggs that come out of there.

    The sacred impeller is not significantly lighter now, and the strength has also failed in motorsports. Of course, the old part can also no longer be compared with modern forged rims.

  • That's why forged wheels for all the sports car and luxury sedan manufacturers in the world are lying there.


    No point in going into further detail here.

    The sacred impeller is dead. The new forged wheels are mounted on new new tools. They are not such easter eggs either.

    Fuchs is now but not so the market leader in forged wheels.

    to what is written above,


    Furthermore, the "fibers" of the material are "practically bent" according to the contour.


    So more stable than a casting which is later machined. where then the fibers are interrupted again.


    That's more or less what I learned in vocational school.

    Fuchs is not such a leader in forged wheels now, though.

    I guess you don't know what a tool is and when and why it is (has to be) changed.

    You have no idea.

  • I guess you just want to poke around and defend the sacred impeller. Mr. Gauck would say: "he is a stranger to modernity".


    Why did you ask for alternatives anyway?

  • I would like to extend this by the topic 'dislocations'.

    These multiply by forming and block each other :pfeil: increasing the yield strength.

    This also usually goes so far that the material is no longer deformable and heat is used to partially 'heal' the dislocations.

    They then move again and 'neutralize' each other - vulgo: soft annealing.

    Then it's on to forging.


    The supreme discipline is then:

    Finally, heat treating an extremely kneaded material in such a way that the right compromise between yield strength and ductility is achieved.

    Also known for steel as 'tempering'.
