“Hey Bimmer”, Ultra Racing Stabilizer Bar is available

Under its hood lies a 2.0-liter turbocharged four-cylinder engine paired with an eight-speed automatic as-standard for the BMW G20 330i. As for the BMW G20 M340i, it will get a 3.0-liter turbocharged I6 engine and pair with an as-standard eight-speed automatic.

BMW has put a lot of work into the suspension, ensuring the 3 series handles with the classic balance of sport and comfort. For 330i, the rear suspension comes with a multi-link setup and upgraded M sport suspension (lift-related dampers), also the OEM rear stabilizer bar in 15.2mm is equipped. It was similar on the M340i, but the difference is an electronically-controlled unit and also the upgraded OEM rear stabilizer bar in 17.5mm.

Based on the photo shown below, the OEM rear stabilizer bar couldn’t be seen as it was hidden above the subframe. 

How many bars available for BMW G20?

In Ultra Racing, the bars that are available for the BMW G20 330i and G20 M340i are Front Strut Bar, Rear Anti Roll Bar, Front Lower Bar, Mid Lower Bar and Rear Lower Bar.

The functionality of each of the bars after installed on your BMW 3 series are explained below.

STAGE 1 (Front Strut Bar & Rear Anti Roll Bar)

Stage 1 which includes Front Strut Bar and Rear Anti Roll Bar, is the primary set to enhance the performance of your car.

Front Strut Bar / Front Tower Bar

                                 BMW G20 3 Series  Front Strut Bar

The BMW 3 Series doesn’t come with the OEM front strut bar from the car manufacturer. Ultra Racing has developed a 2 points front strut bar, located at the top of the absorber (left and right) in order not to affect the normal procedure of service and maintenance.

The car chassis will affect the left and right strut tower and suppress changes in body distortion that occur during running. Furthermore, continuous stress will cause distortion little by little. As known by majority, tire friction, suspension forces, defects from rain water and old car with age will affect a car’s life span. Aftermarket suspension and modifications will also increase the burden of the car chassis. 

One of the methods to deal with such a situation is to install a front strut bar/front tower bar, by connecting the left and right strut towers to increase rigidity. Apart from being easy to install, it is the most effective reinforcement part that demonstrates high performance.

Rear Anti Roll Bar / Rear Sway Bar

                                 BMW G20 3 Series  Rear Anti Roll Bar 19mm

The OEM rear suspension setups of the BMW G20 330i comes with multi-link suspension and OEM rear stabilizer bar. The OEM rear anti roll comes with a solid 15.2mm. Thus, Ultra Racing decided to develop a solid 19mm, the purpose of upgrading the OEM rear anti roll bar as it significantly improves the handling performance and maintain the comfortability of the car.

A normal road is not flat as a race track, it comes with an uneven and bumpy road surface. When the left and right suspension alignment are different such as during cornering, the stabilizer twists the bar and suppresses the roll by its restoring force. This will result in an understeer or oversteer and also there’s a risk to lose control if over body roll. 

By installing the suitable size of anti roll bar, it is possible to suppress the roll of the vehicle’s body without stiffening the suspension and improving cornering and traction. In addition, since the left and right wobbling is suppressed and the posture is stable, there is no discomfort and the risk of motion sickness is reduced.

STAGE 2 (Lower Arm Bar)

Stage 2, comprising Front Lower Bar, Mid Lower Bar and Rear Lower Bar for BMW G20 330i and G20 M340i are able to reduce the car chassis flex and strengthen the main chassis platform. It is highly recommended for heavy load vehicles such as SUV or MPV as it helps to enhance the stiffness and handling during higher speed and cornering.
