If you appreciate fantastic handling even when driving to the extreme, Powerflex is the solution. Powerflex bushes are made of a special type plastic (polyurethane) which lasts longer and is 25-30% harder than the material standard bushes are made of. It is not without reason that Powerflex has been used on racetracks for many years. Besides better handling, the tyre wear will be reduced because of the better bushes.
