Proper wheel spacers for a Porsche must maintain hub-centric fitment to preserve the vehicle’s precise handling characteristics. Finding the best wheel spacers for porsche isn’t just about looks—it’s about safety and performance. You want a set that bolts on perfectly without vibrations or wobbles.
Many Porsche owners add spacers to push the wheels out for a wider stance. This fills the wheel wells better and can improve cornering stability. But cheap spacers can ruin your driving experience or even cause damage.
In this guide, you’ll learn exactly what to look for. We’ll cover materials, fitment types, and the top brands that Porsche enthusiasts trust. By the end, you’ll know how to choose spacers that keep your car safe and looking sharp.
Why Hub-Centric Fitment Matters For Your Porsche
Your Porsche’s wheels are designed to center perfectly on the hub. This is called hub-centric fitment. When you add spacers, you must maintain this centering.
Lug-centric spacers rely on the lug nuts to center the wheel. This can cause vibrations at high speeds. Hub-centric spacers have a raised lip that fits into the wheel’s center bore. This keeps everything aligned.
For a Porsche, hub-centric is non-negotiable. The car’s suspension and steering are tuned for precision. Any misalignment will be felt in the steering wheel.
What Happens With Non-Hub-Centric Spacers
If you use spacers without a hub ring, the wheel might not sit perfectly flat. This leads to:
- Steering wheel shake at highway speeds
- Uneven tire wear
- Stress on wheel bearings
- Potential lug nut loosening over time
Always choose spacers that include a hub-centric ring or are machined as one piece. This is the first rule for any Porsche.

Rennline Wheel Spacers
Rennline is a Porsche-specific brand. They make parts exclusively for these cars. Their spacers are designed with the exact specifications of each model.
Rennline spacers are machined from 7075 aluminum. This is stronger than 6061. They are also lighter, which helps reduce unsprung weight.
Each spacer is anodized black or silver. The hub-centric lip is precisely sized. Rennline also includes longer lug bolts with a tapered seat.
Rennline Vs. Other Brands
Rennline is more expensive than BMS or ECS. But you get Porsche-specific engineering. If you want the best possible fit, Rennline is worth the extra cost.
Many track-focused Porsche owners choose Rennline. The strength and precision reduce the risk of failure under hard cornering.
How To Choose The Right Thickness
Spacer thickness is measured in millimeters. Common sizes for Porsches range from 5mm to 25mm. The right size depends on your wheel and tire setup.
Too thick and your tires may rub the fenders. Too thin and you won’t get the look you want. Here’s a general guide:
- 5mm to 10mm: Subtle stance, minimal change
- 12mm to 15mm: Moderate stance, fills wheel wells
- 20mm to 25mm: Aggressive stance, may require fender rolling
Always test fit before committing. Jack up the car and turn the steering lock to lock. Check for clearance at the fender and suspension components.
Measuring Your Current Clearance
- Park on a level surface
- Turn the wheel fully to one side
- Measure the gap between the tire and the fender
- Repeat on the other side
- Subtract 5mm for safety margin
This gives you the maximum spacer thickness you can use without rubbing. For the rear, also check clearance to the inner fender liner.
Installation Tips For Porsche Wheel Spacers
Installing spacers is a straightforward job. But you need to do it correctly. Mistakes can lead to loose wheels or damaged threads.
Tools You’ll Need
- Jack and jack stands
- Lug wrench or torque wrench
- Torque wrench (required)
- Anti-seize compound (optional)
- Thread locker (if recommended by manufacturer)
Step-By-Step Installation
- Loosen the lug nuts while the car is on the ground
- Jack up the car and place on jack stands
- Remove the wheel
- Clean the hub surface with a wire brush
- Slide the spacer onto the hub
- If using studs, install them now
- Mount the wheel onto the spacer
- Hand-tighten the lug nuts
- Lower the car to the ground
- Torque the lug nuts to spec (usually 96-118 ft-lbs for Porsche)
After 50 miles, re-torque the lug nuts. Spacers can settle and bolts may loosen slightly. This is normal.
Common Mistakes To Avoid
Even experienced DIYers make errors. Here are the most common pitfalls:
- Using spacers that are too thick without checking clearance
- Forgetting to re-torque after initial drive
- Using lug nuts that are too short (must engage at least 7 full turns)
- Installing spacers on dirty or rusty hubs
- Mixing spacer brands on the same axle
Avoid these and your spacers will serve you well for years.
Material Matters: Aluminum Vs. Steel
Most spacers are made from aluminum. It’s lightweight and resists corrosion. Steel spacers are heavier but stronger.
For a Porsche, aluminum is the standard. It reduces unsprung weight, which improves handling. Steel spacers are rarely used except for extreme applications.
Look for 6061-T6 or 7075 aluminum. These are aerospace-grade alloys. They offer the best strength-to-weight ratio.
Anodizing And Coating
Anodizing creates a hard, corrosion-resistant surface. Black anodized spacers look stealthy. Silver anodized is more traditional.
Some spacers have a painted finish. This can chip off over time. Anodizing is more durable.
If you live in a snowy area, anodized spacers resist road salt better. This is a good choice for daily drivers.
Wheel Studs Vs. Lug Bolts
Porsches typically use lug bolts. The bolt goes through the wheel and into the hub. With spacers, you need longer bolts.
Some spacer kits convert to wheel studs. Studs are installed into the hub, and you use lug nuts to secure the wheel. This makes wheel changes easier.
Studs are popular on track cars. They allow faster tire changes. For street use, bolts are fine.
Bolt Length Requirements
The bolt must engage at least 7 full turns into the hub. Measure the depth of the threaded hole. Add the spacer thickness to the wheel’s mounting surface thickness.
Most spacer kits include the correct length bolts. If not, you need to measure and buy separately. Never use bolts that are too short.
Spacer Kits Vs. Individual Spacers
Kits include spacers, bolts, and sometimes hub rings. They are convenient and ensure compatibility. Individual spacers may require you to source bolts separately.
For most people, a kit is the best choice. It saves time and reduces the chance of mistakes. Brands like H&R and ECS offer complete kits.
If you buy individual spacers, match the bolt thread pitch. Porsche uses M14x1.5 on most models. Verify your car’s specifications.
Frequently Asked Questions
Are wheel spacers safe on a Porsche?
Yes, when installed correctly with hub-centric spacers and proper torque. Use quality brands and check bolts regularly.
Will spacers affect my Porsche’s warranty?
