Frequently Asked Questions

Will these work with my current wheel studs?

M12x1.5 is a common thread pitch on most vehicles. Verify your stud size before ordering — if your car runs a different thread pitch, these won't thread on properly.

Do the lock nuts come separated from the standard nuts, or are they mixed in?

Lock nuts are included as a separate pair. The remaining 18 pieces are standard extended lug nuts. You'll pair locks with regular nuts based on which wheels need them most.

Can I use these on a track car without concerns?

Aluminum lug nuts handle daily and weekend track duty fine. For sustained high-heat or competition environments, verify your local rules — some sanctioning bodies prefer steel. Standard aluminum hardware is street and road-course safe.

K2 Industries & OUR OWN FAQ's

How do I check fitment?

Check the listing for your year, make, model, trim and engine. Body style, build date and factory options can matter. If the listing is unclear, send FI Performance your vehicle details and the product link or SKU before ordering.

What comes with this part?

Check the product description for quantities, hardware and accessories. Photos may show the part installed with other components. Ask us if you need to confirm whether a part is sold individually, as a pair or as a kit.

Will I need extra parts or modifications?

That depends on the part and your setup. Check for adapters, wiring, coding, tuning, trimming or additional hardware before booking installation. If you already have aftermarket parts, tell us what’s installed.

What should I check for headlights or tail lights?

Match your factory lighting type, connector and body style. Halogen, HID and LED assemblies can differ even on the same model. Check pre-facelift versus facelift fitment and features such as adaptive lights or leveling.

Should I have a shop install it?

We recommend a qualified installer for wiring, engine, brake and suspension work. Inspect the part and confirm fitment before cutting, drilling, painting or modifying anything.

When will my order ship?

Availability and lead time vary by item. If you’re working around a shop appointment or event, contact FI Performance for a current estimate before ordering.

How do returns and warranty claims work?

Contact FI Performance with your order number before sending anything back. Eligibility depends on the item, its condition and the applicable policy. If there’s damage or a defect, keep the packaging and send photos of the part, label and issue.

Is this part intended for street use?

Check the listing for any use restrictions and confirm the requirements where you drive. If you need a specific approval or certification, ask us to verify it for the exact part number before ordering.

What parts are best for my car and goals?

Tell FI Performance your vehicle, intended use and goals. We can help narrow down the right parts and put together a practical modification plan for your build.

Do you offer financing options?

Eligible financing options are shown at checkout. Select the available financing method during checkout to review payment terms and monthly-payment options.

How do I track my order?

When your order ships, FI Performance sends tracking information by email so you can follow delivery progress and view the estimated arrival date.

What payment methods do you accept?

FI Performance accepts major credit cards, PayPal and any financing options displayed at checkout.

How do I know if I have factory Xenon lighting?

Factory Xenon lights commonly have a blue-tinted output and a short warm-up period. Check your owner's manual or send FI Performance your vehicle details so we can help confirm your factory lighting type.

What is the difference between Halogen, HID and LED lighting?

Halogen lighting is the traditional, affordable option. HID lighting typically provides greater brightness, while LED lighting is energy-efficient and long-lasting. FI Performance can help you select the correct option for your vehicle.

How do I prevent lighting condensation?

Condensation can occur as temperatures change. Lighting assemblies are designed to minimize it; contact FI Performance for guidance if you see persistent condensation or have product-specific questions.
