[DeTomaso] Torque question

[boyd casey]

I am still trying to get a straight answer to that question (hub centric vs
lug centric) The vendor said to me "around the time we made your wheels we
were transitioning from lug centric to hub centric construction. I need to
go back and check the records on yours. If they are "Lug centric" I can
supply you with adapter rings to make them "Hub centric". So that answer
leads me to believe that they are "Lug centric' When I pick up my wheel from
the repair shop I am going to compare the back of the wheel to the hub and
see if they are hub centric. My wheels are three piece so I can (possibly )
have my wheel centers reworked to be hub centric , or my hubs or bite the
bullet and get four  new centers that are hub centric at $500 ea. What are
your thoughts on adapter rings to make lug centric wheels hub centric? What
should I do differently if the wheels are in fact Lug centric? Did you see
my answer about the studs? they are not off the shelf Pantera parts they are
12mm x 1.75" 10.9 steel  , and 12mm x 1.5 rh thread. And the lug pattern is
the same as stock  Panteras 4 x 114.3, 4.5 lug diameter. The 1.75" long
studs are also long enough to provide more then adequate thread engagement.
