The BMW M2 has long been the darling of the M-division, offering a compact, rear-wheel-drive experience that harks back to the legendary E30 M3. At Carbonss Tuning, we have had the privilege of working extensively with both the outgoing F87 generation and the new G87 generation. While they share the same nameplate, their aerodynamic profiles and technical requirements for carbon fiber upgrades are vastly different. In this comparative study, we delve into the technical nuances of carbon fiber aerodynamics for the F87 vs. G87 M2.
The F87 M2: Curvaceous and Organic
The F87 M2 (including the Competition and CS models) is defined by its organic, muscular curves. Its aerodynamic profile is relatively streamlined for a performance car, but it suffers from front-end lift at high speeds and a rear end that can become unsettled under heavy braking. Our approach to the F87 has always been about “completing” the lines that BMW started.
For the F87, we recommend:
- The CS Style Front Lip: This lip follows the bumper’s natural curvature, extending forward to catch clean air and create a consistent high-pressure zone. It perfectly complements the F87’s rounded wheel arches.
- Performance Side Skirt Winglets: These small but effective components help manage the air spilling out from the front wheel wells, directing it along the side of the car to the rear diffuser.
- High-Kick Trunk Spoilers: Because the F87’s rear deck is relatively short, a high-kick spoiler is essential for creating enough “spoil” to reduce lift without adding excessive drag.
The G87 M2: Bold, Brutalist, and Geometric
The G87 M2 represents a radical departure in design. It is characterized by boxy flares, sharp angles, and a much wider track. From an aerodynamic perspective, the G87 is much more aggressive from the factory, but its large frontal area creates significant drag. The technical challenge for the G87 is managing airflow around its “brutalist” geometry.
Our G87 carbon fiber catalog focuses on:
- Aggressive Front Splitters: The G87’s large square intakes are perfect for a deep-profile splitter. By extending the splitter further forward and integrating side winglets, we can significantly increase front downforce, which is crucial for a car with such a heavy front-biased weight distribution.
- Full-Length Side Skirts: Unlike the F87 winglets, the G87 benefits from a continuous side skirt that bridges the gap between the massive front and rear flares. This helps maintain a clean “air curtain” along the side of the car, preventing turbulent air from entering the under-chassis area.
- Integrated Rear Diffusers: The G87’s rear bumper is a complex assembly of angles. Our diffusers for this platform are designed to integrate into these factory lines, providing a much larger expansion area for the air exiting from under the car.
Technical Comparison: Aerodynamic Efficiency
When we look at the data, the F87 is naturally “slippery” through the air, but the G87 has much higher potential for generating downforce. The wider track of the G87 allows for a larger underbody area, which means a rear diffuser can be much more effective. However, the G87 requires more aggressive carbon fiber components to overcome its higher drag coefficient.
At Carbonss Tuning, we use 3D CFD (Computational Fluid Dynamics) modeling to ensure our parts for both generations are functional. For the F87, our goal is refinement; for the G87, our goal is maximization. Whether you are driving an F87 M2 Competition or a new G87, the quality of the carbon fiber remains the same: 2×2 weave, pre-preg, and autoclave cured.
Material Integrity and Fitment Challenges
The F87’s curved surfaces require exceptional precision during the layup process to ensure the weave doesn’t distort. Our master craftsmen are experts at maintaining the “perfect weave” even on the most complex radii. The G87, with its sharp 90-degree angles, presents a different challenge: ensuring that the carbon fiber remains strong at the “corners” without adding unnecessary thickness.
We use 3D scanning to ensure that every mounting point—from the clip-on tabs of the F87 to the bolt-through points of the G87—is 100% accurate. We know that M2 owners are meticulous, and we aim to meet that standard with every part we produce.
Driving Dynamics: The Carbon Fiber Effect
On the track, the difference is palpable. An F87 equipped with a Carbonss Tuning aero kit feels more stable at the limit, with a front end that “points” better into corners. A G87 with our full carbon suite feels like a different animal altogether; the added downforce helps mask the car’s weight, allowing it to carry significantly more speed through high-speed sweepers.
We also emphasize weight reduction for both platforms. Replacing the factory plastic components with carbon fiber helps offset some of the G87’s increased mass and further hones the F87’s already excellent agility.
