Why 20mm Spacers Are Popular

20mm spacers are ideal for:

• Aggressive flush fitment
• Wider stance without excessive poke
• Improved wheel positioning
• Better suspension and brake clearance
• Daily-driven performance setups

Basically, enough stance to look good without destroying drivability.

[CRAFTSMANSHIP] Customadeonly wheel spacers are crafted by the automated CNC process in our 4 Axis machining center. Delivering consistent quality & precision to each and every product that produced which gets rid of the balance issue that other brands can have.

Hubcentric Design Benefits

Hubcentric spacers:

• Properly center the wheel on the hub
• Reduce vibration issues
• Improve wheel balance accuracy
• Deliver smoother highway driving

Because shaky steering wheels at 80 MPH are not part of the JDM experience.

[QUALITY] Made with high grade 6061 T-6 aluminum, the fabric is known for high tensile strength and durability. Spacers are assembled with class 10.9 (SAE grade 8) carbon steel studs w/ heat treated. Customadeonly wheel spacers are also backed by our 3 YEAR product warranty against any functional defects.

Forged Construction Advantages

These spacers are:

• Forged for increased strength
• CNC-machined for precision tolerances
• Designed for improved balance and consistency

Which matters when you’re attaching wheels to cars people actually drive hard.

[INSTALLATION] Your Factory wheel studs would possibly extend past the skin of the wheel spacers. On this case, it is important to: 1) Shorten the factory studs 2) The wheels wish to have the open slots (cavities) between mounting holes. 3) Purchase a set of shorter studs and replace them with the factory studs

Performance Benefits

Wheel spacers can help:

• Improve cornering stability
• Widen track width
• Enhance steering feel
• Improve overall appearance

Your 350Z, G37, or GT-R instantly looks lower, wider, and significantly more aggressive.

Installation Notes

• Bolt-on installation
• Verify wheel stud engagement
• Re-torque after initial driving period
• Check fender and suspension clearance before spirited driving

Because wheel fitment mistakes become very educational.

Final Take

No horsepower gains.

But 20mm spacers dramatically improve stance and wheel fitment on Nissan and Infiniti platforms—and honestly, they’re one of the cleanest visual upgrades you can make.
