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.

Performance Street & Track

Wider fitments for enhanced performance

f3caaf295d079a158d399890e2b60eb665146a67-6716x4477.webp

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.

Hardcore Track & Race

All-out performance for fastest lap times

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.

305/30-19 Falken RT660s on our 19x11 ET40s, rear passenger side inner clearance

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:

  • JRZ RS Pro Coilovers
  • KW Clubsport Coilovers
  • Motion Control Suspension (MCS) Coilovers
  • Megan Racing Street Series Coilovers
  • HKS Height Adjustable Springs on Factory Struts

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.

Should I Dial In Negative Camber and How Much Is Right for Me? 

Whether you are a casual weekend track warrior that still enjoys your car on the street, or a hardcore 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 (when dialed in through the top hat / camber plate), it more importantly improves handling, turn-in and tire longevity. Learn more in our blog article The Positives of Negative Camber.
