Couldn't load pickup availability
Build the G87 M2 front aero around the RM Engineering GT4+ chassis-supported splitter kit. A carbon front lip and airdam sit above a foam-core composite lower splitter with molded airflow tunnels and dedicated structural brackets.
Design and construction
The tunnels are part of the splitter geometry, while the brackets provide support through the front structure. Titanium and aluminum skid blocks protect underside contact areas. This is a complete structural aero installation rather than a cosmetic bumper lip.

Fitment and specifications
| Specification | Detail |
|---|---|
| Application | 2023+ BMW G87 M2 Coupe |
| Material | pre-preg front lip and foam-core carbon composite splitter |
| Configuration | chassis-supported tunneled front splitter kit |
This Pit Garage listing focuses on 2023+ BMW G87 M2 Coupe. Confirm the model, installed body panels and existing modifications before purchase. Aftermarket panels and changed mounting points require separate assessment.
RM-reported CFD results
| Integrated Splitter Result | 100 km/h (62.14 mph) | 120 mph V²-Scaled |
|---|---|---|
| Downforce | 41.0 lbf | 152.9 lbf |
| Drag | 7.1 lbf | 26.3 lbf |
| Lift-to-drag ratio | 5.81 | 5.81 |
RM reports these component forces from a complete-vehicle CFD model solved at 100 km/h. Values shown at 120 mph use velocity-squared scaling; they are not a separate 120 mph simulation or measured track result. They do not represent an isolated part gain or a guaranteed axle-load change on your car.
Installation and ownership
Professional installation requires access to front bumper and underbody components. Test-fit the complete system before drilling or trimming; selected factory parts may need modification. Confirm cooling airflow and ground clearance, and never use the splitter as a lifting point.

Product FAQs
Is this interchangeable with the bumper-mounted GT4 lip?
They are different systems. The GT4+ kit adds a lower tunneled splitter and structural support; the bumper-mounted lip is a separate configuration.
What fitment information should I provide?
Provide the chassis, model year, installed bumper or body-panel configuration and any existing aero parts. Vehicle names alone may not establish compatibility after modifications.
Do these specifications guarantee a performance gain?
Dimensions and construction identify the product. Aerodynamic results depend on the complete vehicle, part position, ride height and operating conditions; the listing does not guarantee a specific lap-time or downforce gain.
