If you’re a Porsche 911 owner looking to give your ride a more aggressive stance and improved handling, wheel spacers are likely on your radar. These simple accessories allow you to push your wheels outward, creating a wider track and potentially unlocking better traction and cornering performance.

But how big is too big when it comes to wheel spacers on a Porsche 911? That’s a question with no one-size-fits-all answer, as numerous factors come into play – your specific 911 model,  wheel/tire specs, and driving style all influence what’s a safe and performance-enhancing wheel spacer size versus one that could compromise safety or handling.

As a general rule of thumb, most 911 experts recommend sticking to wheel spacers between 5-15mm per wheel when using high-quality components from a reputable manufacturer. Larger spacers up to 20-25mm can work for some setups but require very precise installation and alignment to avoid potential issues.

What type of Porsche 911 wheel spacers are safest?

Not all wheel spacers are created equal. If you want maximum safety and performance benefits from running spacers on your Porsche 911, quality should be the top priority.

Forged AL6061-T6 with Tensile Strength ≥ 310MPa. To create their featherweight yet ultra-strong wheel spacers, BONOSS utilizes premium AL6061-T6 aluminum alloy forgings with an exceptional minimum tensile strength of 310MPa. This aerospace-grade material provides immense strength and stiffness to easily handle the loads and stresses generated by hard driving.

Multi-stage Hubcentric Design, More Stable at High-Speed. Rather than a simple flat spacer design, BONOSS wheel spacers incorporate a precise multi-stage hubcentric design that centers the wheel perfectly on the hub for exceptional high-speed stability and safety. This virtually eliminates the potential for dangerous wheel vibration or looseness.

ISO Grade 12.9 Wheel Bolts with Gasket Structure, Strength ≥ 1282MPa. The precision-machined wheel bolts included with BONOSS spacers are constructed from ultra-high strength ISO Grade 12.9 material with a mind-boggling minimum tensile strength of 1282 MPa. A special gasket structure helps maintain uniform clamping force over time.
