BMW M5 and M6 gets a performance kit from Dinan

Dinan is well-known for modifying BMW in the States, and has built up a reputation for building supercharger kits for the Bavarian make. In recent years they have also dabbled into building engines for Daytona Prototype race cars that compete in the Rolex Grand Am series of endurance events.

Now though, they have unveiled their latest creation, a Dinan S3 kit for the BMW M5 and M6 performance models. The upgrade package includes both exterior and engine modifications, with technology used from their knowledge from the race track.

The 5.0 litre engine of both cars has been increased in displacement, up to 5.7-litres. The ECU has also been reprogrammed, with the engine now able to produce a whopping 628bhp. As a result, the cars are able to go from 0-100km/h in a rapid 3.8 seconds.

Other modifications include a new free-flowing exhaust system, a shorter 3.91:1 limited slip differential for enhanced acceleration and even power distribution across the rear axle as well as Stage 3 suspension setup for improved handling. New Dinan Brembo big brakes go along with the 19-inch lightweight Dinan alloy wheels for improved stopping power.
