Product Description

The RS-R XNSPH064PUF is a pair of camber adjustable pillowball front upper mounts for the 2017-2021 Honda Civic Type R (FK8) and 2023+ Civic Type R (FL5). These mounts replace the factory rubber top hats with motorsport-grade PTFE-lined spherical bearings, bolting the front strut directly to the chassis without any rubber compliance in the load path. The result is immediate steering response, precise weight transfer on corner entry, and direct road surface feedback that the factory upper mount cannot deliver.

Rotation of the CNC-machined 6061-T6 aluminum plate provides up to ±3° of camber adjustment and +1° of caster -- dialed in at alignment without any additional hardware. Designed for use with RS-R coilover systems, these mounts are confirmed compatible with the RS-R Best-i (FK8) and Best-i Active (FL5) coilover kits. Wheel alignment required after installation. Made in Japan by RS-R.
