What Do Wheel Spacers Do?

Wheel spacers move the wheels outward from the hub.

Benefits include:

Improved Fitment

Reduces factory wheel tuck.

Wider Track Width

Can improve stability.

Better Brake Clearance

Allows room for larger brake components.

Aggressive Appearance

Creates a flush wheel setup.

For many enthusiasts, spacers are the final step toward achieving proper wheel fitment.

Why RSX Owners Use 20mm Spacers

The factory RSX wheel fitment leaves plenty of room between the wheel and fender.

Many owners install spacers to achieve:

Flush Fitment

Brings wheels closer to the fender edge.

Better Stance

Creates a more purposeful appearance.

Wheel Clearance

Helps clear upgraded brake systems.

Improved Visual Balance

Particularly useful with aftermarket wheels.

A properly sized spacer can dramatically improve the way a car looks without changing the wheels themselves.

Hubcentric Design Matters

One of the most important features of this spacer kit is its hubcentric design.

What Is Hubcentric?

A hubcentric spacer uses a center bore that matches the vehicle hub.

Benefits include:

• Better wheel centering
• Reduced vibration risk
• Improved load distribution
• Easier installation

Cheap universal spacers often rely solely on wheel studs, which can lead to balance issues.

Hubcentric spacers help eliminate that problem.

Forged 6061-T6 Aluminum Construction

Material quality is critical when selecting wheel spacers.

These spacers are manufactured from:

6061-T6 Aluminum

Benefits include:

High Strength

Excellent structural integrity.

Lightweight

Adds minimal unsprung weight.

Corrosion Resistance

Suitable for daily driving conditions.

Durability

Commonly used in performance applications.

This material is widely trusted throughout the automotive industry.

CNC Machined Precision

The spacers are produced using:

Four-Axis CNC Machining

Advantages include:

• Precise tolerances
• Consistent fitment
• Better balance
• Improved manufacturing quality

Precision machining helps ensure a vibration-free installation.

Pre-Installed High-Strength Studs

The spacer kit utilizes:

Class 10.9 Carbon Steel Studs

Benefits include:

• High tensile strength
• Heat-treated durability
• Reliable clamping force

Quality wheel studs are essential because they handle significant loads during acceleration, braking, and cornering.

Performance Benefits

While wheel spacers don’t add horsepower, they can improve vehicle dynamics.

Wider Track Width

Moving wheels outward slightly increases track width.

Potential benefits include:

• Improved stability
• Better cornering confidence
• More planted appearance

Results vary depending on suspension setup and wheel specifications.

Installation Considerations

Before installing wheel spacers:

Verify Wheel Stud Engagement

Ensure proper thread engagement.

Check Fender Clearance

Particularly on lowered vehicles.

Torque Properly

Always follow manufacturer torque specifications.

Perform Alignment Checks

Especially if suspension modifications are already present.

Taking shortcuts during installation is never worth the risk.

Daily Driving vs Track Use

These spacers work well for:

Daily Drivers

Improve appearance and fitment.

Show Cars

Create a flush wheel setup.

Canyon Cars

Increase track width slightly.

Track Builds

Provide additional wheel clearance.

Many RSX owners successfully run 20mm spacers for years when installed correctly.

Yes. The spacers are designed for the RSX’s 5×114.3 bolt pattern, M12x1.5 thread pitch, and 64.1mm center bore.

Are hubcentric spacers better?

Yes. Hubcentric spacers help properly center the wheel and reduce vibration risk.

Will 20mm spacers cause rubbing?

That depends on wheel offset, tire size, suspension height, and alignment settings.

Do wheel spacers improve handling?

A wider track width may improve stability, but results vary by vehicle setup.
