The BMW M4 gets a new performance kit, this time from the American tuners at Dinan. The Stage 2 package is actually available for both BMW M3 and M4 and promises additional performance.

To be more specific, the new kit offers extra 56 horses and 58 lb-ft of torque, starting from 4000 rpm. In order to achieve this, Dinan opted for a new carbon cold air intakes as well as a Dinan free flow exhaust system.

The S55 cold air intakes comes with a sealed air box for improved figures while a larger high-flow filter improves the air circulation. Besides the extra power, there’s also improved stability as Dinan installed special anti-roll bars.

They provide a better ride thanks to the new 32mm (front) and 24mm (rear) bars. There’s also a revised MAF sensor which helps in this equation while a carbon fiber tube is improving the air flow too.

You can get a look at Dinan’s high-end parts used for this Stage 2 DINANTRONICS down below. Pricing and availability details are yet to be released.
