Not comfortable with 5mm spacers as there is barely any hub lip left for the rim to sit in as "hub centric". Don't know how you guys race with 5mm spacers...

You can get a hub extender from Turner Motorsport for $40 to safely run a 5mm spacer. They just replace the dust cap.
To run the 275 on the Z4M I had to run the 5mm spacer for strut clearance. That said I recently switched backed down to a 265 because i didnt want to run the spacer due to increased scrub radius. If you can get away without running the spacer do it!
