Carlsson 2/6 Wheel Bore Size

[nmal]

I bought a set of staggered Carlsson 2/6 19" wheels a a couple years back and I'm finally getting around to mounting them to check fit before having them refinished. I want to mount them to see if I like them before spending $ on refinishing and tires.

19x8.5 ET35
19x10 ET30

The front wheels have the correct bore size but the rear wheels have a larger bore. I tried my best to measure and bought bore adapter rings, OD 78.1mm to ID 66.6mm, which do not fit because the OD of the rings needs to be slightly larger.

Would anyone happen to know the bore size of the rear wheels? Also based on the offset it seems spacers would be desirable. The previous owner had them mounted on his E500E so he must have been using spacers + bore adapter. Any guidance is appreciated.

I can't help with the bore size, but a 10" rear wheel with ET30 does NOT need spacers!!

As Dave said, 10j et30 does not need spacers.
I measured some hub rings a friend made for a set of Carlsson 2/6s at about 78.1. Dead battery in my digital calipers and the wheels are gone. I do remember I ended up using commercially bought hub rings. If you look online at companies like "Gorilla hub rings" they should have a listing for the ring. If 78.1 is loose something may not be right with the wheels. Where did you get your adapter rings?

You can mount them with the rings you have to check appearance, but they may create some vibration.
