When it comes to drifting, the BMW M3 and BMW M4 are two of the most powerful and iconic performance cars in the BMW lineup. Both models offer exceptional handling, rear-wheel drive layouts, and powerful engines that make them solid platforms for drifting. But when faced with the question of which is better for drifting—M3 or M4—the answer isn't as straightforward as you might think.
In this blog, we'll dive into the key differences and advantages of each model, including factors like weight distribution, power delivery, and aftermarket support. We'll also explore how modifications like angle kits, toe plates, and suspension upgrades from SLRspeed can enhance the drifting capabilities of both the M3 and M4, helping you make the right choice for your drift build.
Overview: BMW M3 vs. BMW M4
The BMW M3 has long been the gold standard for performance sedans, and the BMW M4, its coupe counterpart, shares much of the same DNA. Both models are powered by the same turbocharged inline-six engine and offer rear-wheel drive layouts, but there are subtle differences between the two that can impact their drifting performance.
- BMW M3: Traditionally a four-door sedan, the M3 is slightly heavier than the M4 but offers excellent balance, stability, and accessibility for both street driving and drifting.
- BMW M4: As the two-door coupe version of the M3, the M4 is lighter and slightly more agile, making it a popular choice for drivers who want sharper handling and a more track-oriented feel.
Both cars share the same core components, but there are a few critical factors that make each one stand out when it comes to drifting.
Power Delivery: M3 and M4 Engines
Both the BMW M3 and M4 feature the same powerful S55 turbocharged inline-six engine, which delivers massive amounts of torque and horsepower. Whether you're drifting at low speeds or entering a high-speed corner, the engine provides plenty of power to break traction and initiate a drift.
- M3 and M4 Power Output: The base model M3 and M4 both produce around 425 horsepower, while the Competition versions can crank out over 500 horsepower. With these power figures, you’ll never have an issue initiating a drift.
Where the difference lies is in the slight weight distribution and chassis feel between the two. The M4 is more nimble due to its lighter weight, while the M3 provides better stability, particularly during longer drifts. So, if you prefer a more responsive car for sharp transitions between drifts, the M4 might be a better option. If you're looking for a more stable platform with slightly more weight in the rear, the M3 might give you better control during extended slides.
Chassis and Weight Distribution
Weight distribution plays a huge role in how easy it is to drift a car. A near-perfect 50/50 weight distribution allows the car to rotate around its center, making it easier to maintain control during a drift. Both the M3 and M4 boast excellent weight balance, but their body styles contribute to some differences.
- BMW M3: The four-door M3 is slightly heavier than the M4, which can translate to better stability, especially during long drifts. The extra weight also means the M3 has a slightly better rear grip, which can make it easier to control the car when sliding at higher speeds.
- BMW M4: The two-door M4 is lighter and a bit more agile, making it easier to throw the car into sharp turns and quick transitions. Its lighter weight means it’s a little more twitchy, but that can also be an advantage for more experienced drivers who prefer a more responsive chassis.
For beginners or drivers who want a more forgiving drift experience, the M3’s extra stability might be beneficial. On the other hand, experienced drifters looking for sharper handling may appreciate the M4’s lighter, more agile feel.
Rear-Wheel Drive and Drifting Capabilities
Both the M3 and M4 are rear-wheel-drive cars (with optional all-wheel drive versions), making them ideal candidates for drifting. In their rear-wheel-drive configurations, both cars offer predictable power delivery to the rear wheels, which is essential for initiating and holding drifts.
- M3: The rear-wheel-drive M3 provides excellent control, and the slightly heavier chassis allows for smoother transitions during long drifts.
- M4: The M4’s rear-wheel-drive setup is equally potent, with the lighter chassis offering quicker responses to throttle inputs, making it easier to break traction at lower speeds.
Both models are highly capable when it comes to rear-wheel-drive drifting, but the M3 might be better suited for beginners or drivers who prefer a more planted feel, while the M4 is ideal for those who want a more agile, twitchy driving experience.
Suspension Geometry and Handling
Suspension geometry plays a critical role in how a car handles during a drift. Both the M3 and M4 come with adaptive suspension systems that provide excellent handling right out of the box. However, aftermarket suspension modifications can significantly enhance their drifting performance.
SLRspeed's angle kits for the M3 and M4 are perfect for increasing your steering angle, allowing you to achieve sharper drifts and maintain control through wider angles. Additionally, SLRspeed toe plates make it easy to adjust the car’s alignment for optimal drift performance, ensuring you have the perfect balance between grip and slide.
Both the M3 and M4 can benefit from upgraded suspension components like coilovers, control arms, and sway bars, which help maintain stability and improve control during aggressive drifts.
Cost of Modifying the M3 vs. M4 for Drifting
When it comes to cost, both the M3 and M4 are relatively expensive platforms to build into dedicated drift cars. However, the M3 might be slightly more budget-friendly due to its availability in both new and used markets, as well as a broader range of aftermarket parts.
- M3: With a larger pool of used M3 models available, the initial investment may be lower than the M4. Additionally, M3 aftermarket parts tend to be more readily available and less expensive than those for the M4.
- M4: While the M4 may have a slight edge in agility and weight, the cost of entry is higher. The newer M4 models can be pricier, and the two-door configuration may limit options for certain modifications.
If you're looking to build a drift car on a budget, the M3 might be a more affordable option. However, if you’re willing to spend a bit more for the agility of the M4, it can be a worthy investment for experienced drifters.
Which Is Better for Drifting: M3 or M4?
So, which one is better for drifting—the M3 or the M4? It ultimately comes down to personal preference and driving style:
-
Choose the M3 if you want a more stable, forgiving platform. The slightly heavier chassis provides excellent balance and rear grip, making it easier to control during long drifts. The M3’s four-door setup doesn’t detract from its performance, and it’s often a more budget-friendly option due to greater availability in the used market.
-
Choose the M4 if you’re looking for a lighter, more agile car with sharper handling. The M4’s two-door coupe design offers quick responses to throttle inputs and is better suited for drivers who want a more engaging, dynamic driving experience. Its lighter weight makes it more responsive during drift transitions, but it requires more skill to manage.
Conclusion: M3 or M4?
Both the BMW M3 and M4 are excellent choices for drifting, offering rear-wheel-drive setups, powerful engines, and near-perfect weight distribution. The M3 is a fantastic option for those who want a stable, reliable platform that’s easy to control, while the M4 appeals to drivers looking for sharper, more agile handling.
Whichever model you choose, SLRspeed offers a range of high-performance parts—including angle kits, toe plates, and suspension upgrades—that can help optimize your M3 or M4 for drifting. Explore our full lineup of drift-specific parts and take your BMW’s drifting capabilities to the next level.
