[s-cars] Stock UrS Lugbolts - are they conical or sperical

[David Mackintosh]

Not only are there conical and spherical (ball) lug bolt seats, but there
are different ball seat radii.  I have OZ SL's, which are ball seat (like
the OEM alloys), but the radius is different, so you should not use the OEM
lug bolts with these wheels.  Keep this in mind if ordering wheel locks as
well.  I got my bolts and RAD locks (much better than McGard, IMO) from Mike
at purems.com.

Another tip:  I had a bear of a time getting my buggered-up oil drain plug
bolt out (PO used the dealer for oil changes), and ended up buying a breaker
bar and 1/2" drive 17mm impact socket, which is six-point, hardened steel,
and has radiused corners.  I replaced the drain plug with a Fumoto valve,
but the impact socket is perfect for lug bolts, even if you always do them
by hand (recommended).  I wrapped it with electrical tape to minimize the
possibility of scratching the finish on my wheels.
