Horizon Motorsport GTS Front Lip with Adjustable Splitter
G80 M3G82 / G83 M4
/01·Design
Designed in-house for the G8X M3 and M4
We designed the GTS front lip in-house for the G8X M3 and M4. The goal was a part that integrates with the car's factory lines and is built for regular street use, not a reinterpretation of an existing design.
The form references two BMW Motorsport cars. The upper lip follows the squared-off front profile of the G82 M4 GT4, and the lower splitter adopts the manually adjustable arrangement of the F82 M4 GTS. We combined and reworked the two for a street-driven G8X.
Development began with a 3D laser scan of a G80 M3, so the lip follows the factory bumper contours and mounts to the OEM attachment points without cutting. Ground clearance is retained for daily driving, the construction is genuine 2×2 carbon fiber, and the splitter can be adjusted or removed for a cleaner front.
/02·Engineering
Two-piece design with an adjustable splitter
The lip is a two-piece assembly: an upper lip and a lower splitter that mounts to it through adjustment slots. The splitter position can be extended, retracted, or removed to run the upper lip on its own.
Because the splitter is the first point of contact with the road, it can be replaced on its own rather than repurchasing the complete lip. We aim to keep the lower splitter affordable to replace, so the upfront cost of the lip is a one-time investment rather than a recurring one.

Frequently asked questions
Does installation require drilling or cutting?
No. The lip uses the factory mounting points with pre-applied 3M adhesive, and all required hardware is included.
How is the lower splitter adjusted?
It mounts to the upper lip through adjustment slots, so you can set how far it projects, or remove it entirely and run the upper lip on its own.
Can the lower splitter be replaced separately?
Yes. The lower splitter is available as a standalone part, so if it is scraped or damaged you can replace just that piece instead of buying the complete lip again. We aim to keep it affordable to replace.
What is the lip made of?
Both the upper lip and the lower splitter are made from genuine 2×2 twill carbon fiber with a gloss finish.
Which cars does it fit?
It fits the BMW G80 M3 and G82/G83 M4 across all model years, including both pre-LCI and LCI cars. The design was developed from a high-accuracy 3D laser scan of a G80 M3, so it follows the factory bumper contours and mounts to the OEM attachment points on any G8X M3 or M4.
How far does the lip extend, and how does it affect clearance?
From the center of the bumper, the lip extends roughly 2 inches outward and sits about 1.5 inches lower. It was designed to retain practical ground clearance for everyday street driving, and the lower splitter can be retracted or removed for a more conservative setup.
What hardware is included, and do I need anything else?
All of the hardware needed to install the lip is included, and the 3M adhesive is pre-applied, so there is nothing extra to buy for a standard fit. The included hardware secures the lower splitter to the upper lip. The lip also reuses several factory fasteners from your bumper, so it is worth checking that the original hardware is still present on the car before ordering. In the large majority of cases it is. If any of it is missing, the pieces can be purchased directly from BMW, and we recommend using only OEM and the supplied hardware.
How is the lip installed?
The lip mounts to the factory attachment points using the pre-applied 3M adhesive and the included hardware, with no drilling or cutting. The lower splitter bolts to the upper lip with the supplied hardware. We recommend cleaning the bumper surface, then dry-fitting and aligning both pieces to confirm the fit before pressing the adhesive down.
