Sway bar bushings are located along the center of the bar. When they wear out, excess play is introduced which causes noise. Turner Motorsport carries OE BMW rubber bushings as well as high quality aftermarket for those looking to upgrade.
This category contains parts that fit the following chassis:
Factory rubber components are a liability. The Powerflex Black Series Rear Anti-Roll Bar Bushing is a track-ready, engineering-focused upgrade designed exclusively for competitive motorsport and high-performance track vehicles.

In high-performance driving and competitive motorsport, precision is everything. Stock rubber bushings flex, deflect, and degrade under load, leading to inconsistent handling, delayed chassis response, and unpredictable dynamic toe and camber changes.

Optimizing the performance of a classic chassis requires eliminating every ounce of slop. Equip your vehicle with Powerflex Black Series bushings to secure the predictable, razor-sharp rear-end control required on the limit.

Factory-issued rubber sway bar bushings are engineered for commuter comfort, meaning they are prone to significant deflection under lateral loads. Over time, environmental exposure and hard cornering cycles cause these rubber units to soften, stretch, and perish, leading to unpredicted handling characteristics, delayed steering response, and vagueness at the limit.

When fractions of a second matter, communication between the chassis and the driver must be flawless. PowerFlex removes the unpredictable deflection of factory bushings, giving your team a more consistent, tunable platform. For grid-competitive performance and bulletproof reliability, equip your chassis with Powerflex Black Series.

In professional motorsport, chassis predictability and geometric stability are non-negotiable. Standard factory rubber bushings are designed for low-frequency compliance, but under dynamic loading, they suffer from significant deflection. This deflection distorts your suspension geometry, slows down anti-roll bar transition times, and masks critical feedback from the rear axle.

If you are chasing tenths on the stopwatch, compliance is the enemy. Upgrading to the Black Series 14mm rear sway bar bushings stabilizes the rear axle under aggressive trail-braking and mid-corner transitions. It's an essential, cost-effective upgrade for any dedicated track car or weekend time-attack build

Factory rubber components are engineered for daily comfort, resulting in high compliance, unpredicted geometry changes, and a delayed chassis response under load.
The Powerflex Black Series is a track-focused upgrade engineered to eliminate this compliance. Manufactured from a rigid 95 Shore A durometer polyurethane compound, these 28mm front sway bar bushings ensure immediate, uncompromised load transfer across the front axle. For dedicated race, track-day, or tarmac rally applications, this component locks down chassis roll geometry and stabilizes the front track width under heavy lateral G-loads.
