Shipping: Ships with tracking. Most orders arrive in 1–3 weeks.

Installation

Every part is direct fit, with no cutting. The product details above say how this one mounts: tape, clips or screws.

Before you peel any tape: test-fit the part, clean the surface with isopropyl alcohol, and install above 60°F so the adhesive bonds. Lips, splitters and diffusers take longer and may need small pilot holes, and LED parts need wiring, so we recommend a professional install for those.

Shipping & returns

Every order ships with tracking. Most orders arrive in 1–3 weeks. Parts marked "Ships from a US warehouse" usually arrive faster. Spoilers, lips and diffusers ship separately because of their size.

Fitment guarantee: if a part doesn't fit the car and years it's listed for, contact us before installing and we'll refund you.

See our Shipping Policy and Refund Policy for details.
