The ACUITY shifter was designed to address all of these areas.

Fully Adjustable Shift Throw

The standout feature is adjustability.

Drivers can:

• Fine-tune shift travel
• Choose a more aggressive setup
• Maintain daily-driver comfort
• Customize the shifting experience

Unlike fixed short shifters, ACUITY allows drivers to find the perfect balance.

Throw Reduction (Si): 24-52%
Throw Reduction (CTR): 15-46%
Gate Spacing Reduction (Sport): 0-36%
Gate Spacing Reduction (Si): 2-37%

Significant Throw Reduction

When adjusted aggressively, the shifter can dramatically reduce throw distance.

Benefits include:

• Faster gear changes
• Less hand movement
• Improved acceleration between shifts
• More responsive driving feel

The difference becomes immediately noticeable.

Aluminum and Stainless Steel Construction

The ACUITY shifter uses premium materials throughout.

Aluminum Components

Provide:

• Reduced weight

• Corrosion resistance

Stainless Steel Components

Provide:

• Long-term durability

Together they create a highly refined and durable assembly.

Included Aluminum Base Bushings

Many factory shifters utilize soft rubber components that allow unwanted movement.

The included aluminum bushings help:

• Reduce compliance

This is one of the reasons the ACUITY setup feels so much sharper than stock.

Drivers commonly report:

The transmission feels more mechanical and connected.

Perfect for Civic Si Owners

A short shifter complements these modifications perfectly.
