Show original supplier description
The Acuity 4-Way Adjustable Performance Shifter is engineered for enthusiasts seeking a more precise and engaging manual transmission experience. Its design focuses on adjustability, allowing users to fine-tune key aspects of the shift feel. The gear throw can be reduced by 34% to 55% compared to stock, while gate spacing can be narrowed by 9% to 41%. Additionally, shift knob height is adjustable by up to 30mm (1.2") up or down, and knob position can be rotated within a 52mm (2") circle for optimal driver ergonomics. Construction of this shifter emphasizes stiffness and durability. It features a robust, all-metal frame, a large-diameter aluminum pivot ball in a wear-compensating spherical race for smooth operation, and a centering spring that provides 3x more force than stock for snappy engagement. These elements combine to reduce compliance, improve shift accuracy, and provide a more confident and feedback-rich shifting sensation, whether on the street or track. This shifter is compatible with a range of Honda and Acura models, including the 2002-2006 Acura RSX/RSX-S, 2002-2006 Honda Integra, and 2001-2005 Honda Civic Coupe (EM) and Sedan (ES). It is also suitable for K-Swap vehicles utilizing an RSX-S transmission or gear selector, though an adapter plate is required to affix the shifter to the chassis. The shifter works with all M10x1.5 and OEM Honda/Acura shift knobs.
