The G8X generation — M3 (G80 sedan, G81 Touring) and M4 (G82 Coupe, G83 Convertible) — is the first M car where BMW leaned hard into the tall, vertical kidney grille. Love it or not, that big front-end canvas is exactly why G8X owners upgrade the exterior faster than almost any other M car. And among all the materials on the market, dry carbon fiber is the one that changes the car the most.
This guide covers the pieces we get asked about most for 2021+ G8X, grouped by zone so you can build in stages instead of all at once. If you only change one thing, start with the grille — it is the single highest-impact swap on the front end.
Quick Picks at a Glance
1. The Grille — Where Most G8X Builds Start
Nothing changes the face of a G80/G81 M3 or G82/G83 M4 as much as swapping the grille. This one is an autoclave-cured dry carbon replacement in 3K twill weave with a high-gloss 2K clear coat, and it is available in five different face styles, so you can pick the exact look instead of settling for one. It is the single most requested G8X part we sell, and in our experience the best first upgrade because it instantly reads as a build rather than a stock car.
EDITOR'S PICK — #1
Five face styles in one listing: CSL (with or without ACC radar cutout, and blank), ST and V. Autoclave-cured dry carbon with 3K twill weave and a high-gloss UV-protected clear coat. A direct fit for the factory grille position for BMW G80 M3 Sedan, G81 M3 Touring, G82 M4 Coupe and G83 M4 Convertible (2021+). Pick the ACC variant that matches your car.

Which variant for your car? If your G8X has the driver-assistance radar behind the grille, choose CSL (w/ ACC). Cars without the radar can use CSL (w/o ACC) or CSL (blank) for a clean, no-cutout look. ST and V are alternative face designs for owners who want something other than the CSL shape. Not sure? Check whether your car has the front radar sensor before ordering.
2. Front End — Lips, Vents & Canards
The MP-style front lip is the default G8X chin for a reason: it extends the bumper line down and forward without looking bolted on. Dry carbon, 3K twill, high-gloss finish for BMW M3 G80 / M4 G82 / G83 G8X (2021+).

6. The Big Pieces — Trunk Lid & Hood

Hoods and trunk lids are the parts where panel gap and overall alignment matter most, because they define the whole silhouette of the car. Ask us for the fitment notes for your specific chassis before you order — G80 sedan and G82 coupe panels are not interchangeable in every case.
Dry Carbon vs. Wet Carbon — Why It Matters on G8X
| |
Dry carbon (prepreg / autoclave) |
Wet carbon (hand layup) |
| Weight |
Lighter — minimal resin content |
Heavier — resin adds mass |
| Strength |
Higher stiffness-to-weight |
Good, but more resin-rich |
| Finish |
Deep, even 3K twill under gloss clear |
Can show resin pooling and weave distortion |
| Best for |
Aero parts, hoods, anything load-bearing |
Small cosmetic trims on a budget |
All of the exterior aero parts in this guide are dry carbon with a 2K clear coat and UV inhibitor — the finish that holds its gloss instead of yellowing after a couple of summers.
How to Build a G8X in Stages
-
Stage 1 — Face: grille first. It is the cheapest way to make the car look modified.
-
Stage 2 — Stance: front lip + side skirts. This alone makes the car look lowered even on stock suspension.
-
Stage 3 — Rear: diffuser and wing, chosen to match the aggression of your front end.
-
Stage 4 — Details: mirror caps, fender vents, canards. These are what separate a parts car from a finished build.
-
Stage 5 — Big pieces: hood, trunk lid, engine bay. Only worth it once everything else is done.

Not for the previous-generation F80 M3 / F82 M4 (2014–2020) — the front and rear profiles are completely different, so F8X and G8X parts are not interchangeable. Also not for the M2 G87 (2023+), which uses its own body panels and grille shape.
Every part in this guide is in stock and ships from our US warehouse. Browse the full range in the G8X M3 M4 (2021-2026) collection, or start with the dry carbon front bumper grille — the upgrade most G8X owners do first.
