I bought these for my 1996 Corvette as they can be used with both the original wheels and my new Z06 replica wheels, eliminating the need to close the lugs in the event of a wheel change switch. I chose these as I always thought that matching lug nuts looked better and offered more security than a mismatched lock per wheel. As this 6 bolt wheel kit comes with 24 matching nuts it offers four spares for in the event of damage or loss when using 5-hole wheels. My kit is in its second winter season with no signs of corrosion, and while it's generally considered good practice to regularly check the torque of the jam nuts, I've never found that they need additional tightening.
