Introduction
The Rocket G900 is the most aggressive wide body language in the G-Class world — sharp, angular, motorsport-inspired. Our G900 Rocket carbon fiber body kit brings that identity to W464 models with a direct-fit dry carbon package, and it has become our most requested wide body conversion. This guide explains exactly what the kit includes, what makes it different from other wide body styles, who it suits, and what to know before you commit.
What the Kit Includes
The G900 Rocket carbon fiber body kit is a complete front-to-rear transformation package:
- Front bumper with integrated splitter and ducts: the sharp, low front end that defines the G900 look, with functional duct openings
- Wide front and rear fender flares: the angular flares that create the Rocket silhouette, molded in dry carbon
- Side skirts with step elements: the connecting line between the flares, with integrated step surfaces
- Rear bumper with diffuser: the diffuser design and quad exhaust openings complete the rear
- Roof spoiler extension: the finishing element of the G900 profile
The entire kit is engineered for W464/W463A direct bolt-on fitment — no cutting, no welding, and reversible with the factory parts retained.
G900 vs. Other Wide Body Styles
Owners choosing between wide body directions should understand the differences:
| Style | Character | Best For |
|---|---|---|
| G900 Rocket | Sharp angles, aggressive stance, motorsport presence | Owners who want the boldest, most aggressive look |
| G800 style | Bold but smoother, more integrated curves | Owners who want aggressive width with a more refined silhouette |
| G63 OEM+ | Subtle factory-adjacent widening | Owners who want width without the visual statement |
If you are deciding between directions, our G800 vs G900 vs G63 wide body comparison covers the full styling breakdown. The G900 direction is the statement choice — there is nothing subtle about it, and that is exactly what its owners want.
Why Dry Carbon
The kit is constructed in genuine dry carbon fiber with a glass-smooth 2×2 twill finish:
- Weight: dry carbon construction keeps the kit light — an important factor on a vehicle as heavy as the G63
- Finish: the deep-gloss, UV-stabilized clear coat delivers the premium appearance that painted kits cannot match
- Durability: autoclave-cured pre-preg material resists the chips and cracking that budget fiberglass kits suffer
- Quality verification: for the full checklist on judging carbon quality, see our guide on detecting quality dry carbon fiber parts
What to Know Before Committing
- Wheel requirements: the wide flares demand a proper wheel setup — typically 10-20mm wider track per side. Budget for wheels and tires as part of the project (see our wheels and tires upgrade guide for fitment planning)
- Professional installation: a full kit install runs 3-5 shop days including fitment and alignment. For the pre-installation verification routine, see our wide body pre-installation checklist
- Maintenance: dry carbon wide body panels need proper protection — see our wide body maintenance guide for the PPF and coating program
- Budget reality: kit plus installation plus wheels is a complete project — our wide body installation cost guide breaks down every layer
