Brake Clearance Information
In the engineering phase of wheel development we 3D scan factory brakes and review 2D aftermarket brake templates in order to optimize our barrel profiles and spoke curvatures. As a result, our wheels offer massive brake clearance so you can run the smallest possible wheel diameter.

Easy upgrades for street-driven cars
These bolt-on wheel fitments are ideal for enthusiasts enjoying their car day-to-day on the street, and they are typically paired with all-season or performance-oriented summer tires. These wheel and tire configurations will improve the appearance and performance of the car without requiring modifications to the factory suspension or alignment. Just bolt-on and enjoy!
While these wheel fitments can be used for track days and AutoX, performance will be left on the table. Drivers that prioritize performance should review our Performance Street & Track and/or Hardcore Track & Race sections below.

Wider fitments for enhanced performance
Whether you enjoy spirited street driving or you are a weekend track warrior chasing lap times, these wheel & tire configurations are ideal for enthusiasts looking for a more dramatic improvement in performance and they are typically paired with performance-oriented Summer tires or track-oriented R-compounds.
Square Configurations
Recommended for enthusiasts that want to mitigate understeer and rotate tires front & rear for extended life. Square configurations may compromise rear-end grip when compared to staggered configurations.

Front Tire Fitment Notes: The implications of fitting wider and taller tires on the Z4 carry over from our experience with the A90/MKV Supra. Learn more here: Supra 18" Wheels Technical Article
Staggered Configurations
Recommended for enthusiasts that prioritize rear-end grip/traction. Wheels and tires cannot be rotated front to rear and large staggers may induce understeer.

Track focused fitments that require significant modifications
These wheel and tire configurations are best suited for hardcore track junkies and club racers competing for a spot on the podium. Everything from Extreme Summer tires to full Racing Slicks are commonly used depending on your experience behind the wheel, class rules, etc.
The majority of these fitments were developed for the A90 Supra. With the architecture sharing between the 2 models, most of the track-oriented fitments developed for the Supra carry over to its convertible twin. One area of concern we noted was a fuel filler pipe and clamp assembly in the passenger side rear wheelwell of the Z4 that came closer to wider 305-section tires.

We've limited our recommendations to slightly narrower tires for rear fitments or spacer notes to account for this difference.
Aftermarket coilovers with a slimmer silhouette in comparison to the stock struts are recommended. Not all aftermarket coilovers provide a slim enough silhouette to accommodate 11” wheels on the front without the use of spacers, so please contact an APEX product expert if you have any questions. List of confirmed aftermarket that allows no spacers:
Additional Negative Camber Required. For both on-track performance and rub-free fitment, we recommend dialing in negative camber with these aggressive track setups. The amount of camber required will vary based on tire choice and ride height.

Whether you are a casual weekend track warrior that still enjoys your car on the street, or a hard core racer competing for a spot on the podium, negative camber is a vital part of chassis setup that has many benefits. Not only will adding negative camber create more room for wider wheel and tire configurations, it more importantly improves handling, turn-in and tire longevity.
