I got these in a Porsche parts lot purchase out of a Porsche race shop, so I am hoping not only are they Porsche, but someone here might know exactly what they fit.

Set of four wheels - look like they have never been used. They are 6 pin in a 3.5" diameter circle, and the pins look to be 3/8" diameter holes on the back, and 5/8" on the front side. They are Chassis Engineering Brand, popular in Can Am, formula car, and all kinds of racing back in the 60s, 70s and 80s.

Similar to Centerlines, obviously, but not that brand. they also have a non-ferrous (maybe Magnesium, just based on the fact it's darker than the aluminum) center disc in between the inner and outer halves (I have an identical set of Porsche fitment wheels from the same purchase).

15x10 - 3 1/16" backspacing 16.0 lbs
15x12 - 3 1/16" backspacing 17.4 lbs


Fitment could be Lola March Indylights, Lotus 23/51 (but too wide for that), FSAE, ?? Appreciate any input that might nail it down for sure. Cast pin hubs unbolt from centers, so could be removed and redrilled for another application, of course.
