Upgrade the rear suspension of your BMW Z4 E85 or E86 2003 to 2009 with the Powerflex PFR5-5630-12 rear shock top mount bracket and bush kit. This polyurethane bush kit is designed for aftermarket rear shock absorbers that use a 12mm pin, delivering sharper handling, improved stability and more consistent tyre contact.

At Nforcd, we use Powerflex poly bushes on our own builds and customer cars. Feedback has been consistently positive, with customers praising the tighter, more precise rear end feel. Powerflex polyurethane is engineered to control unwanted suspension deflection and, when correctly formulated, can be as good as or better than rubber at suppressing noise, vibration and harshness.
