The heavy front end of the E70/E71 chassis subjects front strut mounts, spring perches, and foam guide supports to heavier load cycles. The result is deteriorated foam that results in harsh suspension crash over bumps, and vague steering feedback. This Front Strut Refresh Kit provides all the essential OEM grade wear items required to rebuild your front strut assemblies to original factory specs.

When installing a coilover kit or refreshing your rear dampers, your suspension is only as good as the hardware securing it to the chassis. Worn factory rear upper shock mounts and degraded rubber isolators soft mount your suspension, absorbing dampening forces before they ever reach the dampers and causing loose rear end dynamics under high lateral loads. This Rear Suspension Rebuild Kit packaged by Turner provides every genuine wear component required to properly lock down your rear suspension stack. Designed for enthusiasts who demand precise handling and zero compromise reliability on street or track, this kit replaces aging, compressed factory mounts and fatigue prone single use hardware with factory BMW parts. Protect your suspension investment and keep your rear axle geometry locked in place.
