I recently acquired my first 951. A 1986 model with 62k miles. It came with white phone dials, which I've never seen before. At a recent DE, another driver speculated they might have been added post-purchase since they looked like some sort of Turbo Cup special edition wheel (potentially magnesium). The part number stamped inside is:
951-362-116-00 and ,
There are markings which look like the alloy composition - 6K-AlSi12Mg
Anything special about these or are they run of the mill phone dials just painted white (well done however)? Other markings suggest early offsets as the rim size code ends in 23.3.
Thanks for any help.
