Hamann/OZ PG1's, WTF PCD is this?

[czarlos]

Specs:
Front:18x9.5 et 29
Rear: 18x13 et 33
PCD: 5x1??

Came across a set of Hamann PG1's on craigslist not to long ago and decided to swoop on them. The PO told me that they were Porsche fitment off of a widebody 964. Believing that I took these home with the idea that they'd be 5x130. Currently they are split apart, centers have been done in white and awaiting a redrill (decided after that I wanted them drilled to 5x114.3). But I am still trying to figure out what bolt pattern these are. I suck at measuring and am curious if any of the SW wheel guru's could help me identify what these came off of.

Did Hamann/OZ produce any wheels for the 5x108/5x110/5x112 market around the early 2000's? Help me out guys!

Anyone know?

why dont you just measure it? and if they are for that e36, you dont want 5x130, thats porsche pcd

[czarlos]

I measured them to 105mm, which is an incredibly odd bolt pattern. But my question is moreso what they even came off of. They're getting redrilled so I have a solution and they're going on to my 350z (the e36 will get its wheels rebarreled sometime this year though)

Sounds like you measured from bolt to bolt which works for 4 lug, my guess is they're 5x114.3

[projektzwo]

what the... now which is the right way to do the measurments for 5lugs.... ???

I'm so confused!

is it not stamped on the back side? take a picture of the back side and the center of the wheel.

just measure from the center of one hole to the center of another. its not that hard. just from the picture you posted, it is not bigger then 5x112.

or even better, make a circle that has a diameter of 112mm out of paper, and then put it over the wheel. good starting point as to if it is larger or smaller.

what you said is good about 4 lugs... try it with 5... hehe ...

Correct, that is wrong. You need to measure from the furtherest edge of a bolt hole, to the correlating center of another. Just like the picture posted above.

are you sure they arent 5x120?

ive never seen hamann pg1's on any other pattern.

[1badg35]

same here. the only bolt pattern i thought they made were 5x120 for the pg1. but with that said taking the circle with a diameter of whatever bolt pattern you think is a foolproof way of getting it right no matter how many holes

Yep, i thought that all hamann pg1 are all 5x120 and O.Z pegasus came with other pcd.. I had PG1 before and still have the pegasus..but then again like the people above me, just measure it
