I have a different set of Momo 3 piece wheels (I haven't been able to identify the model #) that have a pretty big "back" barrel, you could possibly reassemble with the barrels reversed and have the bigger barrel be out the outside, they would be pushed out more than 4", and I could take a measurement and see. They are approximately 17x10 and 17x9 (from a Cayman IMSA GT 2.9), I was going to run them on my Cayman but doesn't look like I am going to have my tire trailer hitch resolved anytime soon and so these are just sitting, $800 plus shipping (what I paid) Next time I get to my storage I'll measure the barrel widths and send them to you, if that might work?
Hell ya! Let me know

I took a break from engine work and started on the trunk. I had to ditch the lexan trunk since it probably would have melted so I'm back to the old steel trunk. I was able to pull about a third of the weight off of it by skinning it and cut the first of two holes for the turbos. There will be a hole like this on each side. I think its going to look pretty good once cleaned up and wrapped
