PERFORMANCE
Southern BM can provide all matter of services for all your Performance requirements from simple bolt on upgrades like an Air filter kit, to full engine conversions or Superchargers for your BMW car. If you look at our SBM powered cars you will get an idea of some of the modifications we have done previously. Have a look at our classifieds page to see some of the tuning products we have available.

Engine
We can perform all matter of engine upgrades, rebuilds for road or competition. If you wish to increase your engine capacity then we have stroker kits available or if you wish a strong road engine then that can be accomplished as well. We have basic stage 1 kits available for E36 and E46 cars (including E46 M3) consisting of Air box conversions, ECU performance tune or if you prefer Stage 2 kits with Camshafts, exhaust upgrades, Air intakes, Air intakes manifolds and performance tunes. We can also cater for any desire you have for your performance BMW including bigger BMW engines into smaller BMW cars.

Southern BM have a strong desire for Supercharging as the massive power increase cannot be replicated by any other means than forced induction. Supercharger kits are available for E36’s, E46’s, X5’s, E39’s and M cars. We use and recommend Active Autowerke as our preferred supplier of our forced induction packages.

For E36 M3's, we have Full Carbon Fibre inlet Airbox manifolds, Schrick cams, Alpha N management, JB Racing lightened flywheels and also Eisenmann rear mufflers as kits available for purchase.

BMW 135, 335i
For these cars we recommend the Active Processor.
Active Autowerke is pleased to release a New Active Processor to the public. This is a "piggy back" ecu for the 335, and 135 model BMW. This unit replaces the Xede. Be assured all BMW Xede units in the field from Active still has Active support.

With our continuous pursuit for new Quality technology at economical pricing we have found a new partnership with AEM ( Advanced Electronic Management, a USA leader in electronic technology) enabling us to bring even more economic fairness and quality to the marketplace. Our Active Processor features Digitial Technology with 3-d mapping capability that allows our tuners to maximize your potential gains while making sure your car is still running well within its "safe" limits. The Active Processor also has the capability to be uploaded on the workbench without a wire harness, all that is necessary is a USB cable and a PC with the accompanying "upload" software. Active Autowerke has also implemented a map switching feature (at no extra cost, switch included) which allows the user to switch between maps whether it be a custom map or our basic Stage 1.5 performance map. The Active Processor includes a custom harness kit with detailed installation instructions as well. This unit comes pre loaded with our Stage 1.5 software on our proprietary V3 firmware and is compatible on all current production 335, 535 and 135's. As far as the gains are concerned they are on par with our previous system.

Coupled with the new Active Processor Southern BM offer Active Front mounted intercooler Blow off valves, and Exhaust upgrades to enhance your 135 or 335's performance.


Transmission
At Southern BM we can upgrade your Automatic Transmission with stronger internals if your looking for a power upgrade or if you have an Automatic or SMG car then we can offer you conversions. We have recently done an Automatic to manual conversion and 2 E36 M3’s from SMG to Manual.

Differentials
We can provide different ratio final drive crown wheel and pinion gears and also an arrangement of LSD units. If your looking at taking your car from the road to the track, an LSD upgrade with increased lock is a must.

Exhaust
Southern BM are the Australia Master dealer for Eisenmann Exhaust systems and we use them in conjunction with our performance requirements.


Tuning
We use selected tuners products depending on the application. For the older cars we have selected chips available. For todays cars and Flash tuning we use our Diagnostic tool which has plenty of performance tunes available for most BMW’s. If your looking for custom applications, like Alpha N, we can do that as well. For those of you that are looking for Track use then we can convert the whole injection system over to MoTec. We have used MoTec many times now and it is a clear leader in the field for off road applications. Another we have used is a unit from EFI Technologies, we are currently setting this up on an E34 Alpina.


For Diesel Cars we have our range of Diesel Tuning kits- The Southern BM Black box. You can read more about that by clicking the Diesel Tuning kit link or as an alternative we have flash tunes available for Diesel cars as well.

Styling
There are a lot of options in the Styling market, Alpina, Hartge, ACS, Breyton, Hamann. Currently popular is Vorsteiner for all their Carbon Fibre products, like bonnets, spoilers front and rear diffusers all for current model BMW cars especially E92.


Suspension
We use Koni for our preferred shockers and would like to use more of their FSD range of products and for ride and handling we prefer Eibach Springs for road use. These matched together make for a performance ride and looks to go with it. We use a range of sway bars to match these suspension set ups. We also use Bilstein rebuildable shockers. For the more serious we have coil over set ups for most BMW cars and upgraded solid, or performance bushes and reinforced mounts, to suit any application. Depending on your requirements we will be able to suggest a set up for your application. We can supply and install Front and Rear strut braces and also have chassis body braces for Z3 M Roadsters.


Brakes
There are a number of Big Brake kits on the market. ATE is the manufacturer of the majority of BMW brakes and they have a range of Big Brake kits available for track use, others include Brembo and Stop Tech. If you would like an upgrade for your road car then we can offer bigger brakes for BMW cars as an original equipment upgrade with larger Rotor, caliper and pad size.
