Has anybody fitted the Black Series Powerflex engine mount bushes, I have the yellow ones fitted to mine. Just wondering if they are harder and if they cause more vibration or not.
I’ve got the Lotus Motorsport ones fitted - transform the car.
I’ve got the yellow powerflex ones but would like to consider stiffer as gear selection , particularly into 3rd, is still a problem after torquing up in 2nd.
I refitted my yellow ones from the last car into my new one earlier in the week and i was surprised when i started it up as there was almost no vibration whatsoever. I have not heard of these black ones. Just found some Bump from an Ebay add. i am presuming these are somewhat stiffer than the yellow.

Black Series - “WHY POLYURETHANE SUSPENSION BUSHES?”
Time to do some sums…
Polyurethane has been with us as a specialised plastic for some thirty years. However recent advances have now made it possible to engineer very special properties into this exciting material. Suspension bushes are some of the most highly stressed components fitted to a motor car. They undergo enormous strains and in the most arduous of conditions with no maintenance or lubrication.
The material they are manufactured from is a rubber compound containing natural products which deteriorate with age. It becomes softer and more pliable, resisting the forces placed on it less and less. Therefore allowing more and more movement of suspension components and offering less and less control over the suspension geometry.
This in turn causes accelerated tyre wear, braking instability and poor handling. This is the single biggest reason you can instantly tell the difference driving a three year old car compared to a showroom new one. However even new cars will benefit from POWERFLEX bushes because of their superior design they offer much more effective control of the suspension components to a much greater extent than normal rubber items.
With the technological advances in this material it has been possible to overcome the common problem associated with harder bushes which is increased noise. By correctly engineering the polyurethane compound, bushes can be made 25-30% stiffer than new rubber items but with exactly the same noise absorbing properties. POWERFLEX bushes make sense.
POWERFLEX for prolonged tyre life.
POWERFLEX for improved performance.
POWERFLEX for increased safety.
Powerflex Black Series bushes are specifically designed for motorsport and extreme use. They are manufactured using a Shore 95 compound polyurethane which is up to 25% more resistant to load than the Powerflex road biased range of bushes and up to 80% stiffer than standard rubber bushes.
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.
Performance Developed for ultimate performance using the toughest materials.
Precision Engineered for the most accurate control of chassis geometry.
Practical Manufactured to be easily fitted without the need for special tools.
