Product Details

The Flat 6 Motorsports aftermarket Porsche 997 wheel spacer kit is a complete bolt-on solution for anyone looking to improve the look and handling feel of their 911, Cayman/Boxster, or Panamera. No longer do you need to have your wheels and tires tucked under the wheel wells keeping your Porsche looking dainty. Our spacers add front and rear track to your Porsche vehicle improving handling and adding a beefier and more aggressive look.

We tested several combinations to come up with the optimal size 7mm/15mm wheel spacer kit for all 911s and Cayman/Boxsters using any OEM wheel (or aftermarket with OEM offset specs) regardless of suspension set-up.

Each wheel spacer kit comes complete with 7mm spacers for the front wheels, 15mm spacers for the rear wheels, and 20 extended bolts sized to fit the additional length of the spacer to provide a secure fit to the hub. Our spacer kits are CNC machined from high-strength aircraft-grade 7075 T6 aluminum. They are precisely made to be hubcentric, allowing for perfect fitment and vibration free driving. They are hard anodized in black or silver providing a durable finish and stealth look. Our extended bolts are also black to mirror the OEM look.
