Porsche Powerflex Heritage Collection
The Powerflex Heritage Collection is designed for modern classic Porsche models and older favourites where you want the subtle look of factory rubber but with the consistency and durability of modern polyurethane. At Design911, we offer the full range of Heritage Collection suspension bushes and associated mounts for Porsche models, so you can refresh tired suspension with a discreet, OEM-style appearance.
These dark grey Powerflex Heritage bushes are engineered for road use and everyday enjoyment, giving classic and modern-classic Porsche models a more controlled, precise feel compared with aged rubber components, while keeping the car looking period-correct under the arches.
Why do Powerflex Heritage Collection bushes matter?
As Porsche suspension bushes age, the original rubber softens, cracks and deforms, which can lead to vague steering, imprecise geometry and a generally loose feel from the chassis. The Powerflex Heritage Collection uses modern polyurethane compounds tailored for road use, helping to maintain more consistent suspension location over time than tired rubber, yet still aiming to preserve a civilised ride. The dark, understated finish helps your Porsche look original from the outside, which is particularly appealing on collector cars and well-presented road cars.
- Helps keep suspension geometry more consistent than old, worn rubber bushes
- Offers improved durability and resistance to ageing compared with standard rubber
- Retains an OEM-style, subtle appearance suitable for classic and modern-classic Porsche models
- Supports a tighter, more controlled feel without looking like a visually obvious upgrade
- Well suited to restorations, sympathetic upgrades and regular road use
Common options & kits
Individual replacement bushes
Specific bushes for locations such as wishbones, trailing arms, anti-roll bars and mounts. These allow you to address a particular worn area without changing the entire suspension at once.
- Ideal when you have identified one or two problem bushes
- Lets you tackle the car progressively as time and budget allow
- Useful where only certain positions are known wear points on your Porsche
Matched axle sets or pairs
Bushes supplied as pairs or axle sets so both sides are renewed together. This is a sensible approach on Porsches where symmetrical wear and balanced behaviour are important.
- Helps maintain consistent feel and response from left to right
- Reduces the chance of uneven wear or mixed behaviour across an axle
- Convenient when carrying out routine suspension refresh work
Complete suspension bush kits
Full vehicle kits or larger combinations that group together many of the key suspension bushes in Powerflex Heritage material. These are popular for restoration projects or when you want to refresh most of the suspension in one go.
- Brings the suspension of your Porsche back to a more controlled, cohesive condition
- Can save time versus sourcing individual positions separately
- Well suited to bare-shell builds, major overhauls or long-term keeper cars

- Powerflex – The Heritage Collection from Powerflex uses polyurethane formulations developed specifically for road use on modern classics and older Porsche models. The dark grey finish helps them blend in like original equipment, while the material is designed to offer stable characteristics and good longevity compared with ageing rubber bushes.
When should you review or replace your Powerflex Heritage Collection bushes?
Many Porsche models that now count as modern classics are still running on their original rubber bushes, which may be several decades old. Even if they look intact, rubber can harden, crack or take a permanent set, allowing unwanted movement in the suspension. Choosing Powerflex Heritage bushes is often about gently tightening up a car that feels loose or imprecise, while keeping a subtle, factory-style appearance.
- You notice clunks, wandering, vague steering or imprecise response from your Porsche
- There is visible cracking, splitting or deformation in original rubber bushes
- Tyre wear patterns suggest geometry is no longer being held consistently
- You are carrying out a restoration or major suspension refresh on a classic or modern-classic Porsche
- You want the longer-term stability of polyurethane bushes but prefer a discreet, OEM-style look
If any of these apply, it is a good time to consider Powerflex Heritage Collection bushes so your Porsche continues to feel tight, controlled and enjoyable to drive, while still looking period-correct.
