The SouthernBM and ESS Tuning relationship goes back over 10 years and has seen the development of some of the fastest and most impressive BMWs to hit Australian roads. Developing the best possible ECU software requires time and intimate knowledge of the vehicle you're tuning. We heavily invest in the development and testing on many of the tuning and performance products we offer on our own vehicles to ensure we can meet the expectations of our customers.

Our ECU tuning software is a result of extensive testing and exact calibration from hundreds of dyno tests and thousands of kilometres of driving in all kinds of conditions – from the extreme heat of Arizona, to cold temperatures of Scandinavia and locally here in Australia – to ensure maximum performance gains with improved driveability/fuel consumption but with stock engine longevity.

A full OBDII flash of the ECU is performed to allow for complete control over the engine parameters. Throttle response is optimised in comfort, sport and sport plus modes, the torque management is reprogrammed, and the top speed limiter is removed, along with a number of other small adjustments made to ensure your car performs at its optimal peak without any safety concerns.

Popular models such as the F8x M3/M4, F87 M2 and F1x M5/M6 can also have additional features added to the tune software such as M4 GTS overrun exhaust burble, cold start delete, top speed limit removal and many more. Calibrations for additional modifications such as downpipes, intakes or turbocharger upgrade are also available to ensure you are getting the most from the performance of your BMW.

The OEM hardware of your BMW has its limitations and if you want to see your car reach its full potential you will need not only the right supporting modifications but also the right advice on what works and what doesn't.

For the newer generation of turbocharged BMWs, our complete range of Eventuri and AFE Power intake systems, Wagner Tuning Intercoolers & Downpipes and FTP Motorsport charge pipes are made to the highest possible standards, allowing your car to maximise its tuning potential and maintain efficiency and reliability in all conditions.

Our ESS Tuning supercharger packages for the V8 and V10 generations of the M3, M5 and M6 are the ultimate way to bring that heart in your mouth performance with the day to day useability of a normal road going car.

The raw power of a V8, the high revving scream of a 6 cylinder or the deep growl of a 4 cylinder engine – there is nothing more emotive than the sound of a high class exhaust. No matter the BMW you own, we offer a complete range of exhaust systems from only the best manufacturers in the world such as Eisenmann, Akrapovic, AC Schnitzer and BMW M Performance that will give your car the sound and performance that it deserves.

What use is large amounts of power without grip and handling? Straight line speed is one thing but real performance comes through speed around corners.

SouthernBM only offers the finest bespoke suspension brands from around the world such as KW Suspensions, ST Suspensions, AC Schnitzer and Eibach. Our Quaife ATB Limited Slip Differential retrofit packages for non-M BMW models are renowned as a must have upgrade for those who like to drive.

Braking performance and consistency allows you to have the confidence to take your car to the limit in the safest possible way. Ultimate stopping power that remains consistent translates to speed and performance. When you think of braking performance there is only one brand that comes to mind – Brembo. We offer the complete range of Brembo brake packages to suit most BMW models from the classic GT brake kits to the latest B-M braking systems.

Wheels mean style, wheels mean performance. Our complete range of HRE, Brixton Forged, AC Schnitzer and BBS wheels come in many different shapes and sizes to suit whatever you taste might be.

Everyone has a unique personality so why should your car be any different?

Whether it be for style or substance, SouthernBM is one of Australia's largest suppliers of BMW M Performance exterior and interior accessories. Give your car the look it deserves with some added carbon fibre or alcantara.

Our AC Schnitzer and Sterckenn carbon fibre aero parts provide you with a unique style and touch of class that will make your car stand out from the crowd.

While there is no doubt that your BMW is an impressive machine, that doesn't mean that is exactly perfect for your needs.
