Porsche Hubcentric Wheel Spacers – 5×130 PCD, 71.6 mm Bore | UK Made

Porsche Wheel Spacer Kit

These Porsche wheel spacers are precision CNC-machined hubcentric track widening spacers, built specifically for Porsche 5×130 (5x130) vehicles. Every pair is bored to exactly 71.6 mm centre bore to sit flush on the hub — no vibration, no balancing issues, no adaptors needed.

Fitting Porsche wheel spacers pushes the wheel outward, reducing your ET offset, widening your track, and giving your 911, 718, Boxster, Cayman or Panamera a flush fitment stance that fills the arches properly.

Why Brightstone Engineering Spacers?

• UK manufactured - machined in-house in Britain. Not imported and relabelled.
• True hubcentric fitment - 71.6 mm bore matches the Porsche hub lip exactly for vibration-free running
• 6082-T6 billet aluminium - aerospace-grade alloy, strong and lightweight
• Supplied with extended wheel bolts - correct M14×1.5 ball-seat hardware for Porsche included in every kit
• Lifetime guarantee - covers materials and manufacturing defects
• Brake caliper clearance - adding wheel spacers creates additional clearance between the wheel and brake caliper, making these ideal if you're running or planning to fit larger aftermarket brake calipers

What's Included:

• 2 × hubcentric Porsche Wheel Spacers (your chosen thickness)
• 10 × extended M14×1.5 ball-seat wheel bolts

Porsche Wheel Bolt Specification & Thread Engagement

These spacers are supplied with extended M14×1.5 ball-seat wheel bolts sized to match the standard Porsche OEM bolt length plus the thickness of the spacer. The standard Porsche water-cooled wheel bolt (996 onwards, all 911, Boxster, Cayman, 718 and Panamera) has a shank length of 29mm, measured from the washer base to the end of the thread.

The extended bolts supplied with each kit are sized as follows:

For safe installation, a minimum of 9 full turns of thread engagement into the hub carrier is required. This equates to a minimum of 14mm of thread engagement — equal to the bolt diameter — which is the recognised engineering standard for M14 fasteners.

⚠️ Before fitting, always remove one of your existing wheel bolts and measure the shank length. If your bolts differ from the 29mm standard — which is common with aftermarket wheels, which often have deeper bolt pockets requiring longer OEM bolts — the extended bolts supplied in this kit may not be correct for your application. Contact us before ordering if your existing bolts are not 29mm shank length and we will advise the correct extended bolt for your fitment.

⚠️ Aftermarket wheel warning: Many aftermarket wheels have deeper bolt pockets than OEM Porsche wheels. If your car is running aftermarket wheels, your existing bolts may already be longer than 29mm. In this case the bolts supplied in this kit will be longer still — always verify adequate clearance within the wheel bolt pocket and sufficient thread engagement before torquing to specification.

Porsche Fitment Table

These Porsche wheel spacers are designed for vehicles with a 5×130 PCD (pitch circle diameter) wheel bolt pattern and 71.6 mm hub bore (centre bore). Check both your PCD and centre bore before ordering, fitting the wrong spacer is the most common mistake.

These spacers fit the full water-cooled Porsche 911 range: 996, 997, 991 and 992 generations, covering every variant from base Carrera through to GT3 RS and Turbo S.

These wheel spacers also cover the mid-engine Porsche models: all Boxster generations (986, 987, 981) and Cayman (987, 981), plus the 718 platform (982) in both Boxster and Cayman form including GT4 and Spyder variants. Panamera fitment covers both the 970 and 971 generations across all body styles including Sport Turismo.

Always confirm your vehicle's PCD and hub bore before ordering. These spacers are designed for 5×130 PCD with 71.6 mm centre bore.

Installation:

Professional fitting recommended. Torque wheel bolts to Porsche's specified setting — first stage 80Nm, final stage 130Nm, tightened in a star pattern at each stage. Always use a calibrated torque wrench and re-check torque after 50–100 miles.
