There are numerous CSL style wheels available across all continents and all manufaturers.
Velocity Motoring is probaby the most recognized brand that I have seen.
I have discovered these wheels available from TC Kline Racing that are manufactured under the APEX ARC-8 brand and appear to be the panacea for Z4 owners looking for lightweight, well proportioned wheels that fit the fenders well, and provide the benefits of a lightweight wheel that reduces unsprung weight and provides the performance advantages associated with light weight racing wheels.
Give them a look. The offsets are also very close, and may require only minimum sized spacers to work perfectly. Plus they weigh in at only 18 lbs compared to factory wheels and replacements that typically run in the 24 lbs range.
