    lemmertz vs KPZ steel wheels

    Might have been discussed here before, but could not find sofar. What is the difference between the Lemmertz and KPZ wheels, apart from the manufacturer ;-)?
    Did both deliver to Porsche simultaneously and if yes for different car types, eg 911 vs 912? If no, which 911 mfg periods got which wheels 1964-1966?
    cheers, jacques

    Don't feel bad, question was asked earlier this year with no real answer. Two suppliers manufacturing to the same spec to meed demand?

    The situation wasn't unique to Porsche - Alfa Romeo used 2 different suppliers for the steel wheels fitted to the Giulietta Sprints ... Fergat & Borrani

    Here's what I know. As mentioned before two vendors supplied steel wheels to Porsche for the 911 and 912 models: Lemmerz and Kronprinz (KPZ). Everyone assumes that they all look the same but they look quite different.

    The arch between the rim and the hubcap on the Kronprinz wheel is somewhat flat. The brake-vent holes are somewhat angular and trapezoidal and flush with the surface. The small side of the opening towards the rim is flat. The large side of the opening towards the cap has a modest arch and comes very close to the hubcap.The sides are very flat and have relatively sharp angles where they transition to the large sides.

    The area between the rim and hubcap on the Lemmerz wheel has a pronounced arch. The brake-vent holes are not flush with the surface; they dimple down quite dramatically making the holes look very soft and the center very curvy. The side of the opening towards the rim is flat. The large side has a very pronounced arch and does not come as close to the hubcap. The sides of the vents are very rounded, more so than the KPZ.

    While some believe that KPZ supplied the painted wheels and Lemmerz supplied the chromed wheels, this has been refuted by owners of original chromed KPZs. However, some owners of chromed KPZ rims report the centres being painted grey, others report unpainted centres, whereas it seems all Lemmerz chromed wheels had grey painted centres.

    KPZ 4 1/2 x 15 wheels weigh 13.0 lbs each, Lemmerz 4 1/2 x 15 wheels are heavier at 13.8 lbs each.

    For 1964-1966 911s, whichever brand was in stock was fitted, but brands were not mixed. A little like the toolkit tools. Exact month/year matches were unlikely to be a consideration, so a mix of months was a possibility.

    Around late 1968, early 1969 KPZ became the predominant supplier to Porsche, supplying the 15 1/2 x 15 and 6 x 15 wheel for the 1970-1973 911s, and the spacesaver wheels for the 911, 924, 928 and 944 models.

    And that's all I know about that! (Quote: Forrest Gump)

    Also, with regard to your other question. From my observations, the Lemmerz were more prevalent on the earlier models - 356s and early (64-66) 911/912s. The KPZ appeared to continue on into the 70s. And I think even the spare spacesaver wheels of much later models were KPZ. That said, I have a friend who has original wheels in his MY 1965 911 which are KPZ. And my MY67 912 has Lemmerz dated 10/66. So likely they were used concurrently during the early years of production. Hope this helps!
