F80 F82 M3/M4
4 products
Carbon fiber front lips, side skirts, spoilers and diffusers for the F80 M3 sedan and F82/F83 M4 coupe and convertible. Most front lips and the MP-style diffuser are listed for all three bodies, while side skirts, spoilers and some diffusers are made for one body only.
Choose from the 3-piece Performance-style front lip kit, a GTS-style lip, a lower splitter, canards and a forged carbon corner splitter, then finish the back with an MP-style, forged or V-style diffuser. Mirror covers, seat back covers and fuel caps complete the range. Parts come with a 1-year warranty, and our fitment guarantee covers the car listed on each product page.
BMW F80 F82 M3/M4 buying guide
F80, F82 or F83?
The F80 M3 sedan was sold in the US for the 2015–2018 model years; the F82 M4 coupe and F83 convertible ran through 2020. The three share a front bumper, so most front lips fit all of them, and the MP-style rear diffuser is listed for all three too. Behind the front wheels the bodies differ, so side skirt extensions come in M3 sedan and M4 coupe/convertible versions, and the sedan and coupe each have their own spoilers.
Front lips and splitters
The 3-piece Performance-style kit is a front lip plus two lower splitters. If you want only part of that look, the lower splitter and the canards are sold separately. The GTS-style lip borrows its shape from the M4 GTS. The front upper lips bond onto the bumper corners, and there's a forged carbon corner splitter for the M3. Compare them under F80/F82 front lips.
Spoilers by body style
For the F80 sedan there are CS-style and PSM-style spoilers. The F82 coupe has a PSM-style and a standard lip spoiler. They aren't interchangeable, so pick the listing that names your body. For the F83 convertible, text us at 609-525-4865. See the F80/F82 spoilers.
Rear diffusers
The MP-style diffuser fits the F80, F82 and F83 and bolts up in the factory position using the original bolts. For the M3 sedan there are also a forged carbon 3-piece diffuser and a V-style 3-piece diffuser. See the F80/F82 diffusers.
Side skirts
The M Performance-style skirt extensions and a forged carbon set are made for the F80 M3 sedan; the F82/F83 extensions fit the M4 coupe and convertible. See the F80/F82 side skirts.
Installation
Many F8X parts install with self-tapping screws (supplied) and adhesive tape, and some need drilling, so we recommend a professional installer for lips, splitters and side skirts. The mirror covers bond over the original mirror housings. The seat back covers attach with 3M tape and don't fit the convertible. Test-fit before you drill or paint: installed parts can't be returned. Unless the product page shows a longer lead time, most orders ship within 5 business days.
Frequently asked questions
Do F80 M3 parts fit the F82 M4?
Front lips and the MP-style rear diffuser are listed for the F80, F82 and F83. Side skirts and spoilers are body-specific, and the forged and V-style diffusers are for the F80 sedan. Check the fitment line on each listing.
Will these parts fit an M4 GTS or M4 CS?
The parts here are made for the standard M3 and M4 bumpers. The M4 GTS and M4 CS left the factory with their own front splitters and rear diffusers, so text us at 609-525-4865 before ordering for one of those cars.
Are the F80/F82 parts pre-preg carbon?
Most F8X listings describe real carbon fiber, and a few are forged carbon. Unlike much of our newer G8X range, they aren't described as pre-preg, so check the listing if that matters to you.
Do I need to drill to fit a front lip?
Usually, yes. Most F8X lips and splitters fit with self-tapping screws (supplied) and adhesive tape, and drilling is required, so we recommend a professional installer. The front upper lips bond on instead.
What if a part doesn't fit?
If a part doesn't fit the car listed on its product page, contact us before installing it and we'll cover the return shipping for a refund or replacement. Every part also carries a 1-year warranty. See our warranty.
