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. Our 18" wheels clear the optional factory PCCB.

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.

Performance Street & Track

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. Most notably, these fitments incorporate wider 9” front wheels which provide superior tire sidewall support over the more "generic" 8.5" front wheels. A wider front wheel and tire combination will increase front end grip and close the stagger from front to rear resulting in sharper turn-in and less understeer. This is one of the easiest and most effective improvements you can make to your Porsche from a handling perspective.

We've optimized the offset of our 9" front wheels to to work well with the stock fenders, however, a wide variety of tire compounds can be used and some may require negative camber to fit properly. See fitment notes under each tire configuration below to see if modifications are required. If you plan to track your car, we highly recommended dialing in negative camber regardless of whether your wheel/tire fitment requires it for fender clearance. Negative camber is vital for extracting the most performance and longevity out of your tires, and without the proper amount the outer shoulders of your tires will wear out prematurely and running tire costs will dramatically increase.

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. Most notably, these fitments incorporate wider 9” front wheels which provide superior tire sidewall support over the more "generic" 8.5" front wheels. A wider front wheel and tire combination will increase front end grip and close the stagger from front to rear resulting in sharper turn-in and less understeer. This is one of the easiest and most effective improvements you can make to your Porsche from a handling perspective.

PCA Spec 997 (SP997)

Race series compliant wheels

Spec 997 is a PCA racing series that promotes equal competition between drivers utilizing the 2009-2012 997.2 C2 S (3.8 liters) and C2 (3.6 liters) Coupes. Both six speed manual and PDK transmission are eligible. 

A s pec series or "one-make" series is based on a designated make/model vehicle and requires all drivers to prepare them in accordance to a predetermined set of rules. A field of identical race cars puts an emphasis on driver skill and team preparation, and with costs controlled more drivers can afford to get behind the wheel. This is some of the most exciting and competitive racing out there!

Whether you currently race in Spec 997, plan to join in the future, or you intend to modify your weekend track car in parity with the rulebook so you can accurately compare lap times to racers, any 987 Cayman/Boxster owner can run this approved wheel and tire configuration. In regards to wheels and tires, official rulebook states:

  • 18" wheels are required (8-9" front, 10-12" rear), but may be any commercially available aluminum wheel. 
  • Wheel/tire combined weight must be equal or exceed 40 lbs. for fronts, and 46 lbs. for rears.
  • Spacers are allowed so long as the top of the tire does not stick out beyond the fender.
  • Steel bolts or lug nuts are required. Hubs may be converted to studs in place of wheel bolts.

Should I Dial in Negative Camber, and How Much is Right for me? 

987.jpeg

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, it more importantly improves handling, turn-in and tire longevity.
