  3. Acuity Performance Shifter Centering Spring 10th Gen Civic

    Regular Price: $36.99

    Special Price: $32.99

    This spring was designed to improve the centering action of your 10th Gen's stock shifter. If you've ever found the centering action of your shifter to leave you wanting a sportier feel, the solution is finally here. With a notably increased preload and nearly identical rate, the ACUITY Performance Shifter Centering Spring increases the centering load in neutral without significantly increasing the force required to locate the far gates (e.g. 1/2 and R). The end result is a sportier shifting feel without an increase in driver fatigue or a reduction in drivability.

  4. Acuity K-Series TPS Calibration Harness

  5. Acuity Shifter Base Bushings

    $39.99

    The OEM base bushings on most Hondas and Acuras are made from highly compliant rubber. Thanks to leverage, the small amount of compliance the rubber adds equates to a very noticable "spongy" feeling in the shift knob during shifts. This bushing kit replaces the OEM rubber bushings with rigid 6061-T651 aluminum making for a much more decisive shift, even with a stock shifter. Fits 2001-2005 Honda Civic 2/4 Door, 2002-2006 Acura RSX, 2004-2014 Acura TSX, 2012-2015 Honda Civic, and 2013-2015 Acura ILX

  15. Acuity ESCO Shift Knob for M10x1.5 6 SPD

    $99.99

ACUITY designed the ESCO with the hopes of providing a more refined shift that makes the driver feel more connected to the transmission, and ultimately the car.

  18. Acuity Throttle Pedal Spacer

    $124.99

    You can't wear heels in a race car, but that doesn't mean you shouldn't be able to hell/toe in one.

Move the throttle pedal toward the driver, better aligning the brake and accelerator pedals. Fits 2012-2017 Honda Civic, 2014-2017 Honda Fit.

    $139.99

Altered geometry reduces the mechanical advantage of the rocker to provide narrower, stiffer gates. Much like how a short throw adapter reduces the distance in the forward and reverse direction while changing gears, this Shifter Rocker Upgrade reduces the distance in the left and right direction while changing gears (such as 2 to 3, 4 to 5, etc).

  22. Acuity High-Temp Silicone Radiator Hoses for the '12-'15 Civic Si

    $149.99

    The 9th Gen Civic Si's OEM radiator hoses are made from EPDM rubber.
