The mounting points line up with the factory lower bumper fixings on the BMW Bumpers 3 Series F30.

It fixes from underneath with the supplied screws and clips; removing the rear bumper is not necessary on the BMW Bumpers 3 Series F30.

FRP needs priming and paint before fitting; the gel-coat surface is only a base, not a final finish.

If your car has a factory tow bar, the diffuser may need trimming around the mounting bracket.

This part ships ready for prep and paint, or usable as moulded. The same shape can also be produced in carbon fiber, forged carbon or fiberglass if you are building a set for a show car.

• Same part available in carbon fiber on request
• Set pricing when ordered together with other trim pieces
• Moulded finish for a dark car, or prep for body-colour paint
• Gloss black, satin black or raw grey finish

We ship to more than thirty countries, mostly direct to workshops, tuners and distributors who resell under their own label.

One piece is fine for a first sample – there is no minimum order. When you need volume, the same mould runs batches of 50, 200 or 1,000+ pieces.

The packaging is built for a journey, not a shelf: foam wrap, corner protection and a double-wall carton, so the part arrives as it left the bench.

Wipe with a soft cloth and a pH-neutral cleaner; avoid solvent-based dressings, which can dull the moulded finish.

Because every piece is laid up to order, expect around two weeks in production before dispatch. Tracking is provided, and the 12-month warranty covers manufacturing defects such as de-lamination or a lifting clear coat.

In the box: diffuser, screws, clips and a fitment card.
