Will these fit my wheels without hitting the brake caliper or suspension?

Extended open-end design is made for wheels with deeper offsets or custom fitments. Verify your wheel offset and brake clearance before purchase — test-fit one wheel first if you're running aggressive fitment.

Do I need a torque wrench to install these?

Yes. Refer to your vehicle's service manual for the correct torque spec — most cars fall between 80–120 ft-lbs, but specs vary. Always use a calibrated torque wrench to avoid under- or over-tightening.

Can I mix these with my existing lug nuts?

You can if your existing nuts are the same size and thread pitch, but for consistency and safety, run a full matched set. The locking nuts should be distributed evenly — typically one per wheel.
