Will these work with my wheel spacers?

Yes — the 60mm extended length is designed specifically for spacer applications and deep-dish wheels where standard lug nuts won't reach. Measure your stud protrusion with spacers installed to confirm clearance before installation.

What tightening torque should I use?

Refer to your vehicle's service manual for the correct torque specification. Aluminum nuts require the same torque as steel, but double-check your manual since some vehicles spec differently for aftermarket hardware.

Do I need to replace all 20 at once, or can I mix and match with my existing hardware?

Match all five per wheel for consistency. Mixing different nut designs, materials, or weights on one wheel can cause uneven clamping and vibration. Use all 20 from this set on four wheels.
