[s-cars] Studs and Nuts! for OZ Supperlegarra Wheels

[John Tilden]

Hi Steve,
Perhaps I should have made it clear that the bolts in question are from OZ
and came with their wheels. Perhaps the OZ Radius is different than the Audi
OEM Bolt. I don't have any OEM Audi Bolts left to compare.

Regardless the OZ Bolts have a radius of 12mm (24mm spherical diameter)
while the OEM Porsche Aluminum Nuts have a larger radius that I calculate to
be 14mm (28mm spherical dia)

Are there any S-car drivers out there with OZ Superlegarra wheels installed?
Are you using Studs? What nuts have you used?

I have checked with a machinist buddy of mine and his CNC lathe will make
short work of the Porsche Nuts conversion to 12mm radius. I'll let you all
know how this turns out.

The Bad news is a set of OEM Porsche nuts is $110.00 plus another $55.00 for
4 security nuts, so it gets expensive fast. Stripping the black anodize and
redoing it clear will add some more $$ to this esoteric solution. Who would
think that such a simple conversion could get out of hand so fast!!!

Yes, I know!

John,

the 24mm vs. 28mm difference appears to be consistent with my
observations. this measurement is the outside diameter and is
different because the arc shoulder of the Porsche bolt is 90 degrees
vs. what appears to be 45-60 degrees on the Audi.

while I don't have any arc gauges handy, the shoulders on both appear
to have the same radius of curvature. the only potential problem is
that your lug holes might be drilled too small and not allow the
Porsche lugs to fit (or be tightened - they're 19mm)
