Acuity Instruments 4-Way Adjustable Performance Shifter for the RHD 11th Gen Civic

Important: This shifter is designed for use in Right-Hand Drive vehicles like those sold in Australia, Japan, and the United Kingdom. It will not fit cars made for the United States. Please be sure to order the correct shifter.

Robust enough for the track, Refined enough for the street.

Easily the most capable 11th Gen Civic shifter ever developed, this design represents ACUiTY's latest advancements in shifter architecture and delivers an unmatched shifting experience that can be gracefully adapted to a vast array of driving conditions and driver preferences. This design was refined over 2 years and in the process won 1st and 2nd in a 25hr endurance race**, underwent over 10,000 hours of cumulative testing time, and racked up well over 10 million shifts on our proprietary test equipment. The result is a shifter that feels equally at home in anything from an otherwise unmodified street car to a purpose-built race car.

The shifter's unique architecture, premium materials and high precision components grant it an unrivaled shift feel and confidence-inspiring gear engagement in a form factor that still fits under the factory console and shift boot. Seasoned tuners will appreciate the thoughtful touches like laser-marked tech info, wire harness routing points, and how all 4 adjustments can be changed with just a 5mm hex key. Shift knob height is adjustable within an impressive, class-leading 75mm (2.9") range, and slotted mounting points permit the shift knob position to be adjusted laterally (left/right). Gear throw and gate spacing are also independently adjustable and are easily tweaked thanks to ACUiTY's slotted adjustment design. Using the knob height, lateral position, gate spacing and gear throw adjustments, it's easy to tune the H-pattern of your shifter to suit your own unique driving style.

The shifter's frame is built from a combination of cnc-machined billet aluminum and precision die-cast aluminum to achieve extremely high tolerances in a very stiff, lightweight, and aesthetically pleasing design. At its heart is a swaged, clearanced, PTFE-lined precision spherical bearing that ensures consistent, smooth shifting with minimal friction and great long-term wear resistance. Centering is quick, decisive, quiet, and consistent, compliments of a thick, over-wound centering spring, cushioned spring legs, and ACUiTY's patent-pending rocker spherical joint design. When adjusted to a height similar to the OEM shifter, this shifter delivers approximately 50% higher centering force than stock, and if you want to fine-tune your centering action even further, low-preload and high-preload centering springs are available (sold separately, see SKUs 1981-S01 and 1981-S03).

Whether you're shaving tenths off your lap time or cruising backroads on the weekend, this shifter delivers the precision, customization, and durability needed to elevate your driving experience. Built for real enthusiasts, backed by race wins, and engineered to last.

Adjustment Specs:

• ADJUSTABLE SHIFT KNOB HEIGHT with 75mm range. Adjust your shift knob height between 50mm taller and 25mm lower than stock to put the shift knob in a position that is most suited to your driving style.

• ADJUSTABLE GEAR THROW can be set between 50% shorter and 20% longer than stock and helps to tune your preference for precise, lightning-fast shifts.

• ADJUSTABLE GATE SPACING can be adjusted between 35% narrower and 50% wider than stock. Gate spacing is adjusted independently from throw to help your further personalize shift feel.

• ADJUSTABLE KNOB POSITION thanks to slotted mounting points that allow you to move the whole shifter laterally to move the shift knob closer to or farther from the driver.

• ADJUSTABLE CENTERING FORCE to achieve lighter or more aggressive centering action using the 1981-S01 (low preload) or 1981-S03 (high preload) centering springs (1981-S01 and 1981-S03 springs sold separately)

Engineered to Win:

This shifter’s design builds on many of the great features from ACUiTY’s existing shifters and adds a number of new, innovative touches. Among them are an increased range of adjustments for more customization, less unwanted friction and play for a more premium shifting experience, an increase in overall frame stiffness for improved engagement feel, a reduction in undesirable NVH for driver comfort, and a reduction in unneeded weight to play a modest role in keeping your build light and agile. The height adjustment range of 75mm used on this shifter offers more adjustability than competing designs and any previous ACUiTY shifter. Since height adjustments can positively or negatively impact both gear throw and gate spacing, ACUiTY engineers had to also equip this shifter with more gear throw and gate adjustment range than any of its predecessors. This allows users to achieve both near-stock settings and huge reductions in throw and gate spacing at the lower height settings, and near-stock settings with modest reductions in gear throw and gate spacing at the taller height settings.
