FAQs
Will this rear diffuser fit my BMW 4 Series G26?
It matches the rear bumper shown in the gallery. Compare the valance shape in the photos with your own bumper first.
Is the carbon real?
Yes – carbon fiber with a UV-stable clear coat. Not a hydro-dipped or printed finish.
Do I need to cut the rear bumper?
No. It replaces the factory lower valance section and uses the original mounting points.
How is it shipped?
Made to order, then shipped worldwide with tracking. Reusable protective packaging.
Is the weave direction consistent?
Yes – the weave is laid to follow the shape of the part, so the pattern runs symmetrically on both sides.
