Background to POWERFLEX

EPTG Ltd (European Polyurethane Technologies Group) was formed in the UK in 1996 to take advantage of the significant advances made in the development of polyurethane in recent years.

The company has wide experience in automotive suspension and chassis systems and combining these design skills with advanced polyurethane manufacturing techniques led to the development of a wide range of high performance automotive polyurethane components now known the world over by the product name POWERFLEX.

The stainless steel components are machined on the latest computer-controlled equipment to ensure perfect repeatability and quality.

The moulding and tooling, design and manufacturing are carried out within the factory ensuring very rapid response time to special projects and complete communication between development, prototyping, testing and manufacturing departments. Component manufacturing is carried out with the latest automatic processing equipment ensuring 100% right-first-time quality. Testing of new components is carried out both on the vehicle and on test rigs.

All of these factors combine to make Powerflex the number one performance bushing.

BM Performance Centre stocks and sells both Road Series and Black Series bushes (for track and motorsport use) and suspension components.

Road Series – for Road and fast Road use.

POWERFLEX Road Series bushes improve your cars’ road holding and chassis performance by controlling the amount of unwanted flex in the suspension. This means the suspension is doing what it is supposed to. It means your tyres have greater contact with the road at all times, therefore, improving safety and performance. Correctly formulated polyurethane is as good if not better at noise, vibration and harshness suppression when compared to worn rubber. Our Road bushes offer Prolonged tyre life, Improved performance, Increase safety, and Greater cost-effectiveness.

Black Series – for Track and Motorsport use.

POWERFLEX Black Series bushes are manufactured using our Black 95 Shore A compound to provide maximum control of chassis geometry. They are designed for the Track, ready to Race and are engineered to be the best. This compound can be up to 80% more resistant to load than standard rubber and 25% stiffer than our purple performance material. If your requirements are purely for the ultimate in handling and chassis performance then Powerflex Black Series are unique, offering the most precise and accurate alignment for your chassis.

OUR MATERIALS

Our materials are colour coded to make them easily identifiable. Below explains the shore rating and their common uses.

Red 65A – Used for our Universal exhaust mounts and diesel engine mounts.

Yellow 70A – Mainly used for engine mounts, diff mounts and subframe mounts or areas where the bush needs a lot of movement and absorption.

Purple 80A – Our most common material. This is used in most areas of the suspension and provides the right mix between performance and compliance.

Black 95A – Our hardest material. This is used mostly for our Black Series range or in our Road Series where the vehicle’s standard suspension demands require us to use this hardness of material i.e. in areas of high load.

This is a replacement part that uses our Black Series material to boost stiffness over the original part by 18% to withstand increased loading seen by this position on the car.

Shoe laces aren't great.
Size: 3 Big Kid, Color: Black White
I bought these RUNSIDE kids tennis shoes for everyday wear and school, and overall they’re lightweight, breathable, and comfortable for active use. My child liked how easy they were to put on, and they worked well for running and general play. The shoes themselves feel flexible and pretty comfortable for the price point. The upper material is breathable, which helps during sports or warmer weather, and they don’t feel heavy on the feet. However, the main issue is the original shoelaces. They constantly came untied no matter how they were tied, which became frustrating pretty quickly during the day. We ended up replacing them with better-quality laces, and that solved the problem. Pros: * Lightweight and comfortable for kids * Breathable material works well for active use * Easy for everyday wear and school * Good fit for the price Cons: * Original shoelaces do not stay tied well * Laces needed to be replaced for practical use Overall, these are solid budget-friendly kids’ sneakers that work well once the laces are swapped out. The shoe itself is comfortable and functional, but the included laces are definitely a weak point.

Great shoes
Size: 8 Toddler, Color: Camouflage Gray
Bought these for my three-year-old son, they fit great and they are easy for him to slide on himself. The laces seem to come untied a lot, but otherwise we love them!

My son loves these shoes. He says they’re really comfortable and lightweight, and he can run and play in them easily. So far they’ve held up well. He can fit them. Non Velcro and slip resistant.

Good, but not great! Insert kept falling out.
Size: 3 Big Kid, Color: Black
I bought these for my 8 year old and the insert was loose and had to be played with multiple times before I could get it to stay in place. I eventually had to place a double sided sticky pad to get the insert to stay.
