Acuity - 4-Way Adjustable Performance Shifter for the RSX, K-Swaps, and More

  • Gear throw can be adjusted as much as 55% shorter than stock, and gate spacing can be adjusted as much as 41% narrower than stock
  • Shift knob height is adjustable 30mm (1.2") higher or lower than stock
  • Stiff, snappy centering action thanks to 3x more spring force than stock
  • Wear-compensating, lubricated joints for consistent, quiet operation
  • Stiff, all-metal frame reduces compliance for improved shift accuracy

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

Easily the most capable RSX shifter, the beauty of the ACUiTY 4-Way Adjustable Performance Shifter is due in part to the careful attention to detail and rigorous testing that went into its nearly 1.5-year design process. Shift knob height is adjustable as much as 30mm (1.2") higher or lower than stock, and the knob position can be adjusted within a 52mm (2") circle to help put the shift knob just where you want it.

Gear throw and gate spacing are independently adjustable and allow for mild to rather extreme reductions compared to stock (up to 55% shorter throw and 41% narrower gates). The unique linkage design provides a substantial reduction in throw for quick shifts in a form factor that easily fits under the RSX's console (as well as the DC5 Integra console). This shifter's robust design makes it equally at home in a K-swapped vehicle using an RSX transmission. Using the gate and gear adjustments, it's easy to tune the H-pattern spacing of your shifter to your exact liking.

In addition, the shifter's frame is built from a careful combination of aluminum and stainless steel to improve the frame's stiffness while being mindful of weight. A large-diameter, aluminum pivot ball in a wear-compensating, spherical race provides 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 and re-engineered spring perches. On top of all this, the spherical joint in the rocker has been heavily upgraded over the OEM design to allow for wear-compensation, to avoid the play that typically develops in the OEM shifter. 

What to Expect:

Expect a significantly different and more sporty shifting experience, even when compared to our Stage 1 shifting kit and most similar aftermarket RSX shifters. This is not just another RSX shifter; it was engineered to provide an incredibly satisfying, precise shifting experience. At first, it may take some time to adjust to the extreme reductions in throw and gate spacing, as well as the stiffer centering action, but in a short while, you will find the shifter's precision, short throws, narrow gates and snappy centering making every driving experience an opportunity to put a smile on your face.

You will likely find that the improved precision will lead to more confidence in quick shifts and more consistent shifting in general. Because the shifter is made from much stiffer materials than the stock shifter, shifts will feel more rigid, defined, and confidence-inspiring during spirited driving. The discerning driver will notice more feedback from the gearbox compliments of this rigid construction; this can be useful in determining the quality of your footwork on the clutch and shift timing.

The exact shifting feel is largely up to you, and we highly suggest you take time tuning the gate spacing and throw to your liking before reinstalling the console. The exact ratio of throw distance to gate spacing is a very personal matter; take advantage of the adjustments to make the H-pattern perfect for you. The joints in Acuity's shifter are carefully designed to be low-friction and very efficient at wear-compensating. This means that your shifter will give you a much longer service life than an OEM shifter before any signs of wear are noticeable.
