Will these work with spacers and offset wheels?

Extended design is specifically engineered for wheels with deeper offsets and spacer applications. The extra length prevents thread runout when stud engagement is shallow.

Do I need to retorque these after the first drive?

Aluminum can settle slightly under load. Check torque spec in your vehicle's service manual and perform a retorque after 50 miles of driving as a safety measure.

Can I mix these with my stock lug nuts?

All 20 nuts should be replaced as a set to maintain even clamping force across the wheel. Mixing materials and lengths can create uneven load distribution.
