Have you thought about finding a wheel with the right width + offset?
Here's a handy calculator: https://www.1010tires.com/Tools/Wheel-Offset-Calculator

As a reference point, the 997 Cup came with the following (EXPENSIVE) wheels:
Rear 18x12 ET30 (997.362.140.97)
Front 18x9.5 ET37 (997.362.136.96)

These dimensions would get you +4" in the rear but you would need some hefty spacers (which it looks like you already have) as the inside has 42mm less clearance.

I do eventually want to put some wheels on the car that fit, unfortunately (as you pointed out) 911 wheels won't work. I actually have 18x12" wheels on the back on my 911, all of the extra width is on the inside of the wheel. This is possible on 911s since they have a multi-link rear suspension and don't have the long track arm that gets in the way of the wheel. If anyone knows of a cheap 17" wheel that can be ordered in custom offsets please let me know.

I don't know how these offsets would work or how "cheap" but here is one wheel you can get in configurable offsets:

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

It’s off the jack stands, it’s off the jack stands! As it sits it’s 17”s wider than stock😬





The Boxster also picked up a new stable mate...can you tell what it is?
