Frequently Asked Questions
Will these work with my existing wheels without modification?
M12 x 1.5 is a standard metric fastener size. Your wheels need to be drilled for M12 holes β verify your wheel specs before ordering. Extended L40 profile is designed for modern wheel seating, so check your wheel's lug seat style matches.
Do I need to use both the standard and locking nuts, or can I use all locking nuts?
The set is built with both standard and locking pairs for a balanced approach. You can install all locking nuts if you prefer, but most drivers use the lock-ring pairs on three or four positions per wheel for secure hold without over-constraining.
What's the right torque spec for these?
Refer to your vehicle's service manual for the correct torque value β it varies by application. Aluminum nuts torque similarly to steel, but always confirm your OEM specification before installation to avoid under- or over-tightening.
