Rear Bumper Splitters for BMW F80 M3 & F82 / F83 M4 2014-2020, Carbon Fiber or Matte Black FRP
Available in stock (20)
Rear Bumper Splitters for BMW F80 M3 & F82 / F83 M4 (2014-2020)
Splitter trims for the lower corners of the rear bumper, sharpening the widest part of the M car's rear end and framing the quad exhausts. Two finishes are offered: 3x3 weave carbon fiber for the woven look, or matte black fiberglass (FRP) as a lower-cost alternative in the same shape. Both are finished under a double-layer UV-protected clear coat, developed with 3D design and CNC moulding, and test-fitted on an actual car.
Fitment
- BMW F80 M3 sedan, F82 M4 coupe and F83 M4 convertible

Installation
Professional installation is recommended. These mount with the supplied self-tapping screws rather than adhesive tape, and the screws form their own holes in the bumper, so plan the installation as permanent.
- Clean and degrease the lower corners of the rear bumper, then dry them fully.
- Dry-fit each splitter and mark the alignment and screw positions before driving any fastener.
- Fit the screws evenly, working from the centre of each splitter outward.
- Check that both sides sit level and the gaps match before finishing.
FAQ
What is the difference between carbon fiber and FRP? Carbon fiber shows a visible woven finish and is lighter. FRP is moulded to the same shape in matte black at a lower price.
Is this a tape-on part? No. It mounts with self-tapping screws, so the installation is not reversible.
Do they fit a standard 3 Series or 4 Series? No. Only the F80 M3 and F82 / F83 M4 are covered.
Does it fit the convertible? Yes, the F83 M4 convertible is covered alongside the coupe and sedan.

Ordered the BMW front bumper fog light grille and the fitment was absolutely perfect. Gloss black finish looks factory-fresh and the quality is outstanding. Installation took about 30 minutes — no drilling required. Highly recommend AlchemyRide!

Fast shipping, great packaging, and the part arrived in perfect condition. The grille fits my F23 like a glove — exactly as described. Customer service was also super responsive when I had a fitment question. Will definitely order again.

I've bought aftermarket parts from many stores but AlchemyRide stands out for quality and value. The part was well-made, fit perfectly, and the price was very competitive. My BMW looks aggressive and clean — exactly what I wanted.

Excellent product and super easy to install. The gloss black finish matches my M Sport bumpers perfectly. Shipping was faster than expected and the part was well-packaged. Very happy with my purchase — my car looks completely transformed!
