ACUITY Aluminium Shift Boot Collar - Honda Civic Type R (FK8 / FL5) - Satin Black
The ACUITY Shift Boot Collar replaces the plastic ring at the top of the factory shift boot. It holds the boot up neatly against the knob, fixes sagging boots and removes the fragile OEM ring that tends to crack when knobs are swapped.
The collar is reversible. One side suits traditional narrow-based knobs (about 22mm at the base), and the other suits wider-based knobs such as the Type R style (about 28mm). Two stainless steel binding nuts are supplied, one for flat-bottomed knobs and one for boss-bottomed knobs, and the nut and collar clip together for a clean finish. A built-in retaining feature lets the collar come off and go back on repeatedly without damage.
The collar is machined from 6061 billet aluminium with a sandblasted satin black anodised finish and laser-etched branding. The nuts have 12mm spanner flats.
Note: Suits the manual FK8 and FL5 Civic Type R with OEM or most M10x1.5 shift knobs. Installation by a professional is recommended.
