This is a front pillow upper mount for straight-wound springs with camber angle adjustment. It comes with a spring seat. For the FL5 upper mount, which requires strength and high rigidity, a large-diameter 22φ pillow ball is used, and high-rigidity steel material is used for the mounting bracket. A straight-wound 65φ spring is selected. This pillow upper mount is compatible with the Ohlins damper kit. The shaft diameter is 12φ with a 1.25 pitch, so it can be installed on dampers from other companies.
It is introduced on Ameblo's "M&M HONDA's Honda Honki."
