Does the center fit my brake calipers?
Never ever the wheel can touch your brake calipers. A clearance of 3mm is highly recommended. The h-masz affects the caliper clearance directly. If to small you will get a collision!
This leads to the question: Why should I look for a small h-masz? Most modular wheels do look more attractive with a deep dished outer lip. The smallest h-masz allows for the deepest lip.
