What about our wheel spacer：
High-Strength Aluminum Alloy 6061-T6 ,Forged Material.
Surface treatment: Hard Anodized for durability and corrosion protection.
Machining : CNC machined 0.02mm precision
lugs and nuts : 40cr steel,professional 10.9 grade to increase safety
Limited Life Range Tested for Wheel Bolts/Stud (1 Million Times)
Strength-Tested for Applications (Bolt/Stud/Nut)
Anti-Rust Tested (NSS 72 Hours) for Applications (Bolt/Stud/Nut)

BENEFITS:
1. Increase the car wheel track, reduce the body center of gravity, reducing the body deformation to make the stability of the vehicle greatly ascend
2. To improve vehicle stability and improve handing and other functions
3. Ensure that the car is more flexible, smooth and safe to effectively solve the car speeding when cornering body floated rapidly Floating lateral tilting the phenomenon such as serious

Material
Truly Forged Aircraft Aluminum 6061T6 Alloy , tensile strength 300-310Mpa , yield strength 241-275Mpa,elongation 8-10% ,more better than normal 6061 forged spacer or casting 6061T6 spacer .

Forged Wheel Spacer
Our Wheel Spacer Made from High-Strength Aircraft Aluminum Alloy 6061-T6,
Lightweight,Forged Hard Anodized for durability and corrosion protection insist on using the forged material
The Casting Wheel Spacer material made wheel spacers  will snapped off and pose a very serious threat to the driving safety.

Precision CNC machined
modern CNC machined, the surface was more smooth, increasing car driving more stable and more secure and no vibration. 0.02mm Machining precision,
CNC Machined with 60 degree taper bulge seat lug nuts,Precision Engineered Hub-Centric and Model Specific for Perfect Fit and Wheel Balance.Machine pressed high tensile,heat treated studs.
