Did you keep any of the purchase paperwork that might have specs or size info for your order? I like the set-up you have!
I would contact Devin Stewart at HRE. DevinS at hrewheels dot com I am sure they have the specs for my car but I doubt they would want to make a set for you from those specs as the Boxer is a handmade car and I had them alter the wheels from the original specs for a more aggressive look. HRE is a great company to work with. I really like the look of the 505M and might have gone with that if they were offered at the time. In fact I might order a set of 505M just to have another choice available and who knows how long HRE will offer them.
