Powerflex Rear Upper Wishbone Bush for Mazda MX-5 NA NB
This bush pack replaces the bushes on the rear upper wishbone. Three packs are required per car.
Road Series – for Road and fast Road use.
POWERFLEX Road Series bushes are ideal for fast road cars that may see some track action. These are designed to improve your cars road holding and chassis performance by controlling the amount of unwanted flex in the suspension.
This allows your tyres have greater contact with the road, improving both safety and performance.
The polyethene construction acts more like a bearing than a bush and is pliable enough to absorb harsh unwanted bumps – but hard enough to keep the suspension geometry firmly in place. All this results in not only a longer-lasting bush, but also one that allows a significant amount of handling feedback to be felt by the driver.
Black Series – for Track and Motorsport use.
POWERFLEX Black Series bushes are manufactured using PowerFlex’s Black 95 Duramoter 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 the purple performance material.
If your goal is handling and chassis performance above all else, then the Powerflex Black Series is for you. The Black Series Offers the most precise and accurate alignment for your chassis.
Heritage Collection – for Classic and Restoration use.
POWERFLEX Heritage Collection bushes are perfect for restorations or purely road-going cars. Manufactured using modern-day materials with properties biased for the road, these dark grey coloured bushes will improve any classic cars handling, whilst retaining the same standard appearance of a rubber bush.
The range is designed to fill the gap in the growing demand for quality replacement parts that have an aesthetic keeping with the look of the original part, and the restoration project as a whole, whilst carrying all of the performance and longevity benefits offered by a modern polybush.
Going a step further than simply using the same material and durometer of hardness for all of our parts, each part location has its own durometer designation to ensure improved suspension performance without discomfort or vibration, all of which ship in the new ‘Classic’ Dark Grey colour suitable for all road-based applications.
