The New Era of M
With a striking new look the G8x M4 sets itself apart from its predeceesors. While the looks have been drastically altered from the past, what has not been is its singularly minded approach to being the most intoxicatingly pleasurable coupe (or convertible) on the market. Powered by the new S58 engine capable of delivering up to an astonishing 503 HP and 476 lb-ft of torque. That's good for a factory quoted 0-60 time of 3.8 seconds right out of the box. While power is indeed important, the M3/M4 is synonymous with its track racing pedigree. The G8x power curve is supported by an improved cooling system that has been designed specifically for track use. This is a good thing considering the car will spend a lot of time there with its numerous handling features that crave to be used in such an environment. From the standard Adaptive M suspension, extensive package of bracing, and elaborate assortment of wishbones, ball joints, and links the platform offers precise control with comfort and agility. The vehicle, for the first time ever, also has an AWD variant for maximum grip and confidence inspiring driving. BMW provided a monster. It's up to Dinan to make it an even more ferocious one.

Power Modifications
Additional power is commonly one of the first things people want to improve on their vehicle. However, most don't consider much more than the final power number when making decisions on such modifications. While Dinan strives to give the best results we also take into account reliability, stress on the vehicle, and the various effects additional power may have on other systems in the vehicle. We want to give the consumer an OEM+ experience where they don't need to worry about ramifications and instead focus on enjoying the vehicle just like it came from the factory, albeit with significantly more 'oomph.' Some of the upgrades offered include: Engine Tuning: More Power! IN DEVELOPMENT. Axle Back Exhaust / X-Pipe: Deeper exhaust tone, more volume, no drone. CF Cold Air Intake: Improves throttle response and provides under hood aesthetic beauty.
Suspension Modifications
While stance and 'the look' are considered, Dinan suspension components have the ultimate goal of creating a better tactile driving experience and effectively putting the power generated to the ground for maximum enjoyment. Each individual component has specific goals to achieve that end, but together, they embody a total solution that transforms the vehicle into something entirely different. Some of the upgrades offered include: Coil-Over Suspension: Lowers the car and its center of gravity for reduction in body roll. Sway Bars: Reduce body roll and allows more mechanical grip. Rear Suspension Links: Eliminate deflection and dramatically improves rear end stability. Tension Strut Ball Joint (Monoballs): Improves steering responsiveness and reduces brake shimmy.- Find Your Parts
