In the box
1 rear diffuser with LED light.
Install
Bolts to the M Sport rear bumper with screws. The diffuser has exhaust openings on both sides, built for a dual-side exhaust; a stock F30 exhaust exits on the left only, so the right opening stays open unless you add a tip. The LED needs to be wired in. Professional install recommended.
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.
