Transform the exterior styling of your BMW with the MHC+ GTX Aero Kit for the F80 M3 & F82/F83 M4, a complete pre-preg carbon fibre aerodynamic package engineered as one cohesive design rather than a collection of separate parts. The GTX kit delivers a fully integrated motorsport-inspired appearance while maintaining the factory proportions and aggressive character of the car.
Manufactured from 100% pre-preg (“dry”) carbon fibre, every component offers lightweight construction, superior rigidity and flawless weave consistency, finished in a deep UV-resistant high-gloss lacquer.
Available Configurations
Core Upper Pieces Only – an OEM+ appearance with a premium, aggressive daily-driven aesthetic. Includes:
- GTX Front Splitter
- GTX Side Skirts
- GTX Rear Diffuser
With Front Splitter & Rear Diffuser Lower Attachments – the complete kit, for the ultimate track-inspired appearance. Includes:
- GTX Front Splitter
- GTX Adjustable Front Aero Add On
- GTX Side Skirts
- GTX Rear Diffuser
- GTX Ultra Aggressive Undertray Add On
The kit is modular throughout. Start with the core upper pieces and add the lower attachments later if you prefer – the mounting provision is engineered into every component from the start, so nothing needs modifying when you upgrade.
Key Features
- Designed specifically for the BMW F80 M3 & F82/F83 M4
- Available in two configurations to suit your build
- Manufactured from 100% pre-preg (“dry”) carbon fibre
- OEM-style 2x2 twill carbon weave
- Deep high-gloss UV-resistant lacquer finish
- Developed using full 3D chassis scanning and CAD engineering
- OEM-quality fitment and panel alignment
- Integrated brake cooling duct routing channels
- Adjustable 20–50mm front aero add-on (complete kit)
- Ultra aggressive rear undertray and corners (complete kit)
- Supplied with all required mounting hardware and drill bits
- Backed by MHC LDN’s 3-year warranty
Developed as a Complete Aero System
The MHC+ BMW F80 M3 & F82/F83 M4 GTX Front Splitter sharpens the front-end styling and introduces integrated brake cooling duct channels. The GTX Side Skirts create a clean horizontal profile that visually lowers the car and connects the front and rear styling. The GTX Rear Diffuser adds depth and structure to the rear bumper.
On the complete kit, the Adjustable Front Aero Add On extends the splitter a further 20–50mm forward, and the Ultra Aggressive Undertray Add On extends the diffuser beneath the vehicle for a far more substantial, track-inspired rear.
Fitment & Installation
Fits using: OEM mounting points, pre-applied automotive-grade adhesive tape, supplied stainless steel self-tapping screws and M6 hardware. Your OEM fixings are reused throughout – keep every one you remove.
Tools required – items marked (supplied) are included in the box:
- Drill
- 2.5mm drill bit (supplied) – pilot holes for all self-tapping screws
- 6.5mm drill bit (supplied) – front aero add-on only
- PZ2 driver bit (supplied)
- 10mm socket and 10mm spanner – M6 hardware
- 8mm socket – rear bumper corner OEM fixings
- Panel wipe or IPA and lint-free cloths (alcohol wipes supplied)
- Masking tape

Time to fit – Core Upper Pieces Only:
- GTX Front Splitter – 30 minutes (bumper stays on the car)
- GTX Side Skirts – 30 minutes for the pair
- GTX Rear Diffuser – 15 minutes, OEM mounts only
- Total: approximately 75 minutes
Time to fit – With Lower Attachments:
- GTX Front Splitter with Adjustable Front Aero Add On – 90 minutes (requires bumper removal)
- GTX Side Skirts – 30 minutes for the pair
- GTX Rear Diffuser with Ultra Aggressive Undertray Add On – 15 minutes
- Total: approximately 135 minutes
Difficulty: Moderate – drilling required. The times above are working times; we would recommend setting aside an unrushed half to full day for the complete kit so that surface preparation, trial fitting and alignment are never hurried. Best fitted indoors, above 15°C, on a clean, dry car. A full step-by-step GTX fitting guide is available, and professional installation is recommended for the best possible result.
Precision OEM-Level Fitment
MHC+ developed this component using:
- Full 3D scans of the BMW F8X chassis
- Advanced CAD modelling and engineering
- OEM-level panel alignment development
This ensures flush integration with the factory body lines, accurate panel alignment and OEM-style fitment quality. No cutting or compromise required.
Premium Pre-Preg Carbon Fibre Construction
Unlike conventional wet carbon fibre products, MHC+ uses genuine pre-preg (“dry”) carbon fibre, delivering:
- Increased strength and rigidity
- Reduced overall weight
- Superior weave consistency
- Minimal imperfections or air pockets
- Exceptional long-term durability
Each component is cured under controlled heat and pressure to achieve optimal resin saturation, producing a premium carbon fibre part suitable for high-end BMW builds.
Deep High-Gloss Finish
Finished in a premium UV-stable gloss lacquer, every GTX component offers:
- Excellent resistance to fading and yellowing
- A rich OEM-style appearance
- Seamless compatibility with other MHC+ carbon fibre components
Supplied Ready to Install
