ACUITY Aluminium Shift Boot Collar (Satin Black) – Honda Civic Type R FK8 / FL5

The ACUITY Aluminium Shift Boot Collar (Satin Black) is a clean, permanent fix for sagging shift boots and cracked OEM plastic rings. It allows the use of virtually any M10×1.5 shift knob in your Honda without compromising the fit and finish between the shift knob and the boot.

The collar is reversible to match traditional narrow-bottomed knobs (≈22 mm base) and newer wide-bottomed styles (≈28 mm base). A retaining feature lets you remove and refit the collar repeatedly without stressing the boot ring. The kit includes two stainless steel binding nuts (flat-bottomed and boss-bottomed types, each with 12 mm wrench flats). The collar itself is precision-machined from 6061 billet aluminium with an anodised, sandblasted finish and laser-etched branding.
