Porsche Centre Lock Wheel Guide Pin

Centre lock wheels are widely used on modern high-performance Porsche models because they replace traditional multi-bolt wheel fastening systems with a single central locking mechanism. This design is derived from motorsport and allows for quicker wheel changes and reduced unsprung mass.

However, centre lock wheels are typically large and heavy, which makes them difficult to handle during removal and installation. Without proper support, the weight of the wheel can cause alignment issues, accidental drops, or damage to expensive braking components.

Fits:

• Porsche 997.2 - 2009 to 2012 
• Porsche 991.1 - 2012 to 2016
• Porsche 991.1 - 2016 to 2019
• Porsche 992.1 - 2019 to 2024
• Porsche 992.2 - 2024>>

The Centre lock Wheel Guide Pin is designed to safely support the wheel during installation and removal, helping align the wheel with the hub while carrying its weight.

What This Centre lock Wheel Guide Pin Does

This guide pin threads into the wheel hub after the centre lock nut has been removed. Once installed, it acts as a support shaft for the wheel, allowing the wheel to slide onto or off the hub in a controlled manner.

This tool helps:

• Support the full weight of the wheel during removal and installation
• Maintain alignment between the wheel and hub spline interface
• Reduce the risk of accidental wheel drops
• Protect expensive brake components during wheel changes

Why You Need a Centre lock Wheel Guide Pin

Prevents Operator Fatigue and Injury
 Centre lock wheels are heavy and awkward to handle. This tool reduces the physical strain involved in aligning and supporting the wheel.

Protects Carbon-Ceramic Brakes
If a wheel slips during installation or removal, it can easily damage painted brake calipers or costly carbon-ceramic brake discs (PCCB). The guide pin keeps the wheel securely supported.

Prevents Wheel Damage
Dropping a wheel during installation can scratch or damage the wheel finish. The guide pin allows controlled positioning during fitting.

Improves Wheel Alignment
The tool helps guide the wheel onto the hub spline interface, making installation smoother and more precise.

Premium Construction for Wheel Protection

The PF99-610-30 guide pin is precision machined from a combination of high-strength materials designed to protect both the wheel and hub.

Construction includes:

• High-strength Delrin
• Durable polyurethane
• Anodised aluminium components

These materials provide strength, durability and excellent protection against scratching or marking wheels and hubs.

Convenient Storage and Workshop Use

Each guide pin is supplied in a reusable plastic twist tube, keeping the tool protected when not in use. This makes it ideal for:

• Professional workshops
• Porsche specialists
• Track day preparation
• Home mechanics working on centre lock-equipped cars

PowerAlign Wheel Mounting Guide Pins are designed to allow the safer mounting and easy alignment of heavy alloy wheels on most common cars to use lug bolts.
Available singularly to suit a specific vehicle or as a handy 4-piece workshop kit.
The individual pins come supplied in a handy reusable plastic twist tube for protection when not being used and the 4-piece workshop kit is supplied with a steel storage case for pride of place in your toolbox.

The individual pins come supplied in a reusable twist tube and the 4-piece workshop kit is supplied with a steel storage case for pride of place in your toolbox.

 Simply thread the appropriate pin size into one of the bolt holes on the wheel hub. The wheel can then be lifted and placed on the guide pin, and easily slid into place on the hub; keeping the bolt holes aligned for other bolts to be inserted and tightened.

This reduces the awkward and back-straining process of holding the wheel in place with one hand whilst lining up and threading in the first bolt; thus, reducing the risk, hassle, and strain of mounting wheels.

Proven using simulated and real-world testing, the new mounting pins use high-strength CNC-machined AISI 303 Stainless Steel, some 50% stronger than plated mild steel, to ensure durability and resilience in a workshop environment, and are supplied with colour-coded 3D-printed protective sleeves for ease of identification and anodised 2011-T6 aluminium caps to absorb knocks and prevent damage to the wheel, unlike others on the market.

The Powerflex Range:

Road Series (Road & Fast Road) - POWERFLEX Road Series bushes improve your cars’ road holding and chassis performance by controlling the amount of unwanted flex in the suspension. This means the suspension is doing what it is supposed to. It means your tyres have greater contact with the road at all times, therefore, improving safety and performance. Correctly formulated polyurethane is as good if not better at noise, vibration and harshness suppression when compared to worn rubber. Our Road bushes offer Prolonged tyre life, Improved performance, Increase safety, and Greater cost-effectiveness.

Black Series (Track & Motorsport) - POWERFLEX Black Series bushes are manufactured using our Black 95 Shore A compound to provide maximum control of chassis geometry. They are designed for the Track, ready to Race and are engineered to be the best. This compound can be up to 80% more resistant to load than standard rubber and 25% stiffer than our purple performance material. If your requirements are purely for the ultimate in handling and chassis performance then Powerflex Black Series are unique, offering the most precise and accurate alignment for your chassis.

Heritage Collection (Classic & Restoration Use) - POWERFLEX Heritage Collection bushes are manufactured using modern-day materials with properties biased for the road. These dark grey coloured bushes will improve any collector’s car, whilst retaining the same standard appearance of a rubber bush. Our new range speaks to the growing demand for quality replacement parts that have an aesthetic in keeping with’ the look of the original part and restoration project as a whole whilst carrying all of the performance and longevity benefits offered by Powerflex’s unique blend of polyurethane. Going a step further than simply using the same material and durometer of hardness for all of our parts, each part location has its own shore designation to ensure improved suspension performance without discomfort or vibration, all of which ship in our new ‘Classic’ Dark Grey colour suitable for all road-based applications.

Powerflex Materials:

The materials used by Powerflex are colour coded to make them easily identifiable. Below explains the shore rating and their common uses.

Red 65A – Used for our Universal exhaust mounts and diesel engine mounts.
Yellow 70A – Mainly used for engine mounts, diff mounts and subframe mounts or areas where the bush needs a lot of movement and absorption.
Purple 80A – Our most common material. This is used in most areas of the suspension and provides the right mix between performance and compliance.
Black 95A – Our hardest material. This is used mostly for our Black Series range or in our Road Series where the vehicle’s standard suspension demands require us to use this hardness of material i.e. in areas of high load.

Grey* - Used specifically for our Heritage Collection. This can be any of the durometers mentioned but will always be the same as the equivalent part from our Road Series i.e. if it’s Purple 80A in our Road Series, it’d be Grey 80A in our Heritage Collection. On our Road Series and Heritage Collection kits, we can use a mix of all 4 of our materials. During the development stages, we test the original bush and see what the requirements are for strength and movement. At that point, we then decide which of our materials would be best suited. We don’t believe in a one material suits all rule. Manufacturers will do the same and will use different shore rubbers, however, it’s not as noticeable as all rubber bushes look visually similar.

Yellow 70A – Mainly used for engine mounts, diff mounts and subframe mounts or areas where the bush needs a lot of movement and absorption.
Purple 80A – Our most common material. This is used in most areas of the suspension and provides the right mix between performance and compliance.
Black 95A – Our hardest material. This is used mostly for our Black Series range or in our Road Series where the vehicle’s standard suspension demands require us to use this hardness of material i.e. in areas of high load.

Grey* - Used specifically for our Heritage Collection. This can be any of the durometers mentioned but will always be the same as the equivalent part from our Road Series i.e. if it’s Purple 80A in our Road Series, it’d be Grey 80A in our Heritage Collection. On our Road Series and Heritage Collection kits, we can use a mix of all 4 of our materials. During the development stages, we test the original bush and see what the requirements are for strength and movement. At that point, we then decide which of our materials would be best suited. We don’t believe in a one material suits all rule. Manufacturers will do the same and will use different shore rubbers, however, it’s not as noticeable as all rubber bushes look visually similar.

*NOTE: Porsche updated the 924's front anti-roll bar design during the 1982 model year. If your 1982 Porsche 924 has a VIN from F 92-CN402 198 onward (or F 92-CN450 832 onward for North America), it will be compatible. 

For 1982 Porsche 924 Turbo models, compatibility starts from F 93-CN100 306 onward (or F 93-CN150 332 onward for North American and Japanese models). Please ensure you check your VIN to confirm fitment. If you're unsure, please do not hesitate to contact us with your vehicle's VIN number for confirmation.

Additionally, due to the vehicle's age and some ambiguity in the official catalogue, we highly recommend measuring your anti-roll bar before ordering to ensure you select the correct size.

The Powerflex Range:

Road Series (Road & Fast Road) - POWERFLEX Road Series bushes improve your cars’ road holding and chassis performance by controlling the amount of unwanted flex in the suspension. This means the suspension is doing what it is supposed to. It means your tyres have greater contact with the road at all times, therefore, improving safety and performance. Correctly formulated polyurethane is as good if not better at noise, vibration and harshness suppression when compared to worn rubber. Our Road bushes offer Prolonged tyre life, Improved performance, Increase safety, and Greater cost-effectiveness.

Black Series (Track & Motorsport) - POWERFLEX Black Series bushes are manufactured using our Black 95 Shore A compound to provide maximum control of chassis geometry. They are designed for the Track, ready to Race and are engineered to be the best. This compound can be up to 80% more resistant to load than standard rubber and 25% stiffer than our purple performance material. If your requirements are purely for the ultimate in handling and chassis performance then Powerflex Black Series are unique, offering the most precise and accurate alignment for your chassis.

Heritage Collection (Classic & Restoration Use) - POWERFLEX Heritage Collection bushes are manufactured using modern-day materials with properties biased for the road. These dark grey coloured bushes will improve any collector’s car, whilst retaining the same standard appearance of a rubber bush. Our new range speaks to the growing demand for quality replacement parts that have an aesthetic in keeping with’ the look of the original part and restoration project as a whole whilst carrying all of the performance and longevity benefits offered by Powerflex’s unique blend of polyurethane. Going a step further than simply using the same material and durometer of hardness for all of our parts, each part location has its own shore designation to ensure improved suspension performance without discomfort or vibration, all of which ship in our new ‘Classic’ Dark Grey colour suitable for all road-based applications.
