Vehicle Covered in this Guide 2002-2008 Z4M Roadster (E85) and Coupe (E86). Fitment is identical between all Z4M models.
Chassis Introduction The E85/86 Z4M is a favorite among many for its performance potential and unique styling. Because of the dramatic offset difference front-to-rear, the Z4M really lends itself both visually and mechanically to staggered fitments. With the right suspension and alignment modifications, rotatable square fitments can be used as well.

Easy upgrades for street-driven cars
These fitments prioritize (in order): 1. Ease of fitment 2. Aesthetics 3. Performance
Ideal for the driver who wants a no-nonsense direct bolt-on fitment. These fitments are a small step up from stock wheels and tires, and offer a small but noticeable performance improvement.
Staggered Setups
Maintains stock-like handling characteristics, tires can only be rotated left to right. Maximizes both front and rear tire width.
Aggressive fitments focused on appearance and concavity
These fitments prioritize (in order): 1. Aesthetics 2. Performance 3. Ease of fitment
Ideal for the driver who wants to fill out the wheel wells with the widest possible rubber and perfectly flush offsets. Sometimes these fitments are a direct bolt-on, but often times require small spacers, negative camber, or rolled fenders for the sake of dialing in the perfect blend of function and form.
Staggered Setups Maintains stock-like handling characteristics, tires can only be rotated left to right. Maximizes both front and rear tire width.
Wider fitments for enhanced performance
These fitments prioritize (in order): 1. Performance 2. Ease of fitment 3. Aesthetics
These fitments are effective for both performance-oriented street cars and weekend track warriors. The suspension type, alignment settings, and tire brand/size can be changed accordingly to work for either scenario.
Square Setups Recommended for most types of street and performance driving. Allows proper front-to-rear tire rotation to extend tire life & improve handling balance.

These no-compromise fitments are ideal for dedicated track / race cars. They rely on aggressive negative camber specifications and often require rolled rear fenders to prevent rubbing. Since you'll be using all available real estate under the fender arches to accommodate these wide wheels, coilovers with linear race springs are a must for inner clearance (JRZ, MCS, Ground Control, AST, Moton, etc.).

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.
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.

About Camber Plates Adjustable camber plates do more than just aid in wide wheel and tire fitment. They provide increased grip and reduced tire wear by spreading the load evenly during cornering. Learn more in our blog article, The Positives of Negative Camber.
We have tested many brake kits with the wheels listed in this guide. Please email us with any questions related to brake clearance, we’ll be happy to help.
