Dinan has been tweaking and customizing BMWs for years, and the latest BMW to get the Dinan treatment is the M4. In Dinan trim, it’s called the S1 M4, and it packs an impressive 530hp under the hood. The big thing here is that this particular car isn’t as extensively modified as some previous Dinan models.
Rather than gutting the engine and starting from scratch, the car has $7247 in engine mods. Those mods include a DinanTronics signal conditioner, a free-flowing muffler, and a carbon fiber cold air intake. These tweaks might not sound like much individually, but they collectively add up to an additional 105hp and 98 lb-ft of torque.
Performance Enhancements
The Dinan mods carry a warranty that protects the car for four years and 50,000 miles. The modifications push the car from zero to 60mph in 3.8 seconds, which is surprisingly slower than the stock M4 that Car and Driver tested last year. Dinan explains that the M4 is underrated from the factory, making real gains on their in-house dyno more like 46hp and 58 lb-ft of torque. This discrepancy highlights the conservative nature of factory ratings and the potential for aftermarket enhancements to unlock hidden performance.
Upgraded suspension components also play a crucial role in the car’s enhanced performance. The S1 M4 can pull an impressive 0.97g on the skidpad, showcasing its improved handling capabilities. This is particularly beneficial for enthusiasts who enjoy pushing their cars to the limit on winding roads or track days.
Additional Features and Considerations
Beyond the engine and suspension upgrades, Dinan offers a range of additional features that can further enhance the driving experience. For instance, the exhaust system not only improves performance but also provides a more aggressive and satisfying exhaust note. The carbon fiber cold air intake not only contributes to the power gains but also adds a touch of visual flair under the hood.
One of the standout aspects of Dinan’s approach is their commitment to maintaining the reliability and drivability of the vehicle. Unlike some aftermarket tuners who prioritize maximum power at the expense of everyday usability, Dinan ensures that their modifications integrate seamlessly with the car’s existing systems. This means that owners can enjoy the benefits of increased performance without sacrificing comfort or reliability.
Moreover, Dinan’s warranty offers peace of mind to customers who might be concerned about the potential impact of modifications on their vehicle’s longevity. The four-year, 50,000-mile warranty is a testament to Dinan’s confidence in the quality and durability of their products.
For those looking to further personalize their S1 M4, Dinan offers a range of cosmetic upgrades as well. These can include carbon fiber body panels, custom wheels, and interior enhancements. Such options allow owners to create a vehicle that not only performs exceptionally but also stands out visually.
The Dinan S1 M4 represents a balanced approach to performance tuning. By focusing on key areas such as engine management, exhaust flow, and intake efficiency, Dinan has managed to extract significant gains without compromising the car’s inherent qualities. The result is a vehicle that offers a thrilling driving experience while maintaining the practicality and reliability that BMW is known for. Whether you’re a seasoned enthusiast or a newcomer to the world of performance tuning, the S1 M4 is sure to impress with its blend of power, handling, and refinement.
