Identifying Suspension Types

If you’re using coilovers, see the image below to identify which type of coilover spring you have, as it may effect your wheel fitment.

Concavity & Face Profiles

Each of our wheel designs is available in two or three different levels of concavity, which we call Profiles. The Profile is dictated by the width and offset, meaning wide lower-offset wheels will have more concavity, while narrow higher-offset wheels will have less concavity.
