About Powerflex Black Series Bushes

Porsche Powerflex Black Series Bushes

Powerflex Black Series bushes are the most focused suspension bush upgrade available for Porsche models, created specifically for fast road, track and motorsport use. At Design911, we offer the full Black Series range so you can tailor your Porsche chassis for precise, repeatable geometry and a more connected, competition-oriented feel.

Powerflex Black Series - Designed for the Track

Black Series bushes use a very firm 95 Shore A polyurethane compound developed by Powerflex for maximum control of chassis movement. Compared with typical OE rubber, this material is far more resistant to load, flex and deformation, helping the suspension maintain its intended geometry under hard use.

Engineered for geometry control

The key focus of Powerflex Black Series is stability and precision rather than comfort. By significantly limiting bush deflection, these components help keep alignment settings more consistent during heavy braking, cornering and acceleration, which is particularly valuable on track or in aggressive fast-road driving where standard rubber can move and compress.

Track-focused, Porsche-specific applications

Each bush is designed around specific Porsche arms, mounts and locations, with attention to sizing, crush-tube design and lubrication grooves. This Porsche-specific engineering helps ensure that, when installed correctly, the bushes articulate as intended and support smooth suspension movement despite the very firm compound.

What to expect in use

Because Black Series bushes are substantially stiffer than standard rubber and even firmer than Powerflex’s usual performance grade materials, they will generally increase noise, vibration and harshness (NVH) compared with OE. Many owners therefore choose them for focused builds, track-orientated cars, or key suspension locations where geometry control matters most, rather than fitting them in every single position on a daily-driven Porsche.

Choosing Powerflex Black Series for your Porsche

If your priority is crisp response, consistency on circuit days and long-term durability under high loads, Powerflex Black Series bushes are a strong option. If you prefer more road comfort, you may wish to combine Black Series parts in critical locations with softer compounds elsewhere. Our team at Design911 can help you choose the most appropriate combination for your model and intended use.

Installation & setup

Correct installation, lubrication and torque settings are essential with any polyurethane bush, especially a very firm compound like Black Series. After fitting suspension bushes, a proper four-wheel alignment is strongly recommended so your Porsche benefits fully from the more stable geometry. Where applicable, follow Powerflex’s guidance on lubrication and tightening with the suspension at normal ride height.

Explore Powerflex Black Series bushes for Porsche

Browse our Powerflex Black Series range for Porsche models at Design911 to find chassis bushes for control arms, trailing arms, anti-roll bars and other key locations. Whether you are building a dedicated track car or a fast-road Porsche with a sharper, more precise feel, these bushes provide a track-orientated foundation for your suspension setup.
