The Tire Rack. The BR05 is basically a reproduction of the wheels BMW put on the CSL version of the M3. Well, not really a reproduction but I guess a reasonable facsimile without the associated cost. These are only about $660 a set in 18" size. They are 18x8 in the front and 18x9 in the back, exactly like the factory wheels my car came with. I think the offset in the front is a little bit less than stock because it looks like the wheel sticks out just a bit more. I'll have to look up the exact numbers and see for sure.
The black finish is something different for me and I really like the slim machined lip around the outside of the wheel face. The tires are Sumitomo HTR ZIII in 225/45ZR-18 in the front and 255/40ZR-18 in the back. They came perfectly balanced from Tire Rack and ready to mount. The Sumitomos are an underrated tire in my opinion. The Boxster I had came with them and I thought they were great, and the price is very reasonable at around $600 for the set in M3 sizes. They aren't for autocrossing or track days, but for street driving they are a great value.
