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.

Good shorts but they run big
Size: 38, Color: Dusty Olive
I've been losing weight and picked these up in my new size (38). It turns out these are cut for a generous American midsection, and have an elastic fit in the waist, so you can (and probably should!) safely go down a size. I got mine in 34 instead and they fit great.

Great fit, functional, most comfortable shorts!
Size: 30, Color: Anthracite Camo
These are my go-to shorts, I now have five pair in different camo colors! I suggest one waist size smaller than you normally wear, (I buy a 30 instead of a 32, because they stretch and would be too sloppy if I purchased my regular size). The large open slotted pocket on the left, behind the Velcro flap pocket, is perfect for a normal sized cell phone. Plenty of utility pockets for EDC. Since these stretch slightly to accommodate movement and sitting, they are extremely comfortable. Also, my wife says they are good looking on me, so that gets an extra star!

Love the material!
Size: Large, Color: Black
Very soft and beautiful material. The size was perfect. It works well for layering and can also be dressed up. It is not clingy at all. The quality is great.

Worked well for my needs!
Size: X-Large, Color: Black
Nice thick material. I think these could be workout shirts or regular day attire. Soft, wash well, nice stretch, and arm pit gaps aren’t a so wide they look silly or sloppy. Good value for the money. True to size as well.
