To ensure your suspension is as effective and safe as possible, you have to make sure you have used the correct bushes and bumpstops. These small rubber devices are used to protect the larger parts from damaging each other, as well as reducing sound and creating a smoother ride. Check out the selection of bushes at LK Performance. We take suspension very seriously, which is why we only use quality brands like Powerflex. Our Mazda 121 bumpstops are also only of the highest quality too.
