RS-R Upper Pillowball Mounts for FK8/FL5 Civic Type R

RS R Upper Pillowball Mounts for FK8 and FL5 Civic Type R replace the factory style front upper strut mounts with a rigid aluminum upper mount that locates the damper rod in a spherical bearing rather than rubber. On the FK8 and FL5 front MacPherson strut layout, the upper mount is the interface between the strut assembly and the chassis strut tower. Its stiffness and geometry directly affect how accurately the strut top stays positioned under braking, cornering, and steering input.

In factory form, the upper mount uses an elastomer isolator to reduce noise and vibration and to allow small compliance movements. That compliance can allow the strut top position to shift under load, which changes alignment dynamically and can make repeatable alignment targets harder to maintain when the car is driven aggressively. A pillowball style mount addresses this by replacing the compliant isolator with a spherical bearing that articulates while holding the strut top more rigidly in the chassis.

This RS R mount set is a camber adjustable pillowball upper mount design intended to be used with RS R coilover kits. RS R states these pillowball mounts are developed to fit their coilover kits and are not compatible with the factory upper mount arrangement. The design uses an NMB pillowball bearing and a high strength aluminum upper mount plate. RS R also notes that pillowball upper mounts can increase noise and vibration due to their structure and are treated as a wear item, with periodic replacement of the pillowball recommended.

Fitment and selection considerations for an experienced installer typically center on two points. First, this is a front upper mount solution for the FK8 and FL5 Civic Type R chassis. Second, it is intended as a direct matching component for RS R coilovers, rather than a universal camber plate for factory dampers. If your goal is to add front camber adjustability on an RS R coilover equipped car without modifying knuckles or relying on other camber methods, this component is designed specifically for that role.

• Manufacturer part number XNSPH064PUF
• Product type Front camber adjustable pillowball upper mounts
• Position Front left and front right pair
• Vehicle compatibility Honda Civic Type R FK8 and FL5
• Intended suspension compatibility Designed for use with RS R coilovers
• Bearing type NMB pillowball spherical bearing
• Plate material High strength aluminum

Installation and use notes for this style of mount are primarily about alignment and service. Any change to an adjustable upper mount typically requires an alignment after installation and after any later position change. Because RS R identifies pillowball mounts as a structure that can produce additional noise and vibration and treats the pillowball as a consumable item, expected long term maintenance includes inspecting the spherical bearing for play or noise and replacing it at intervals appropriate to the vehicle’s use.
