Circuit Hero EK Shift Plate V2
$55
Our newly redesigned shift plates for EK applications are finally here! What's changed? We now offer 2 color options, brushed and black anodized finishes. Say goodbye to the trim that you had to cut to size. Say hello to the stunning plastic insert resting tight in the opening giving the plate a high end look and feel. Silk screened Circuit Hero logo is sitting nicely in the center of the panel just asking to be photographed! Some of you had experienced clearance problem with certain after market shifters, so we revised the opening. Now the plate will work with B, D and most K-Series shifters.  Made from thick aluminum these Version 2 shift plates bring high end quality to your center console. Plates bolt directly into an EK shift console utilizing the shift boot's factory mounting points. The shift boot must be removed.  Get yours today and forget about an ugly old shifting boot!

Circuit Hero Laser Grip Type-B Shift Knob
$60
We understand that you spend hard sweaty hours working on your build. And we believe that you and your ride deserve the best!  We know you loved our original Type-B Tear Drop knob (well frankly you totally zeroed out our inventory) so we took it a step further and created something truly special. This new design will blow your socks off!  The ball has perfectly round contour to fit right in the palm of your hand, instead of a predictable smooth transition to the stem we added Laser Grip to ensure additional support for more precise shifts. It will feel so natural in your hand with an edge to take you over the top! And hey, we know you asked for branding because you want to represent. And we are giving it to you, because we listen! CNC-engraved Circuit Hero logo at the bottom of the stem is not overpowering but adds that extra special touch, what we like to call a cherry on top!  Machined or polished, this CNC billet stainless steel shift knob will be the last knob you will ever want to buy. We are sure of it!

$325
***DISCLAIMER*** PLEASE READ INSTRUCTIONS BELOW BEFORE PURCHASING. PLEASE DO NOT PURCHASE/ATTEMPT TO INSTALL IF YOU ARE UNABLE TO PUT YOUR VEHICLE ON JACK STANDS AND DROP THE SUSPENSION. MODIFICATIONS MAY BE REQUIRED. Our strut bars are designed with two horizontal steel bars tying each shock tower together. Bars are then welded together with no pivoting parts for maximum chassis rigidity. This will stop your car from flexing during track events as well as during casual spirited driving.  Bars come in raw mild steel and stainless steel. We left the mild steel RAW for customers that like to paint, powder coat, or plate the bars themselves to individually match their car. If you are purchasing the raw version it will have some rust on it and we recommend that you have it treated as soon as possible. FEATURES: Reduced Chassis Flex Improved Handling Single Piece Design Eliminates Need For Adjustment APPLICATIONS: EG/EK Civic DC Integra K-Swap Applications: Motor must be mounted in lower position for valve cover clearance. We manufacture our strut tower bars with extremely tight tolerances. With such tight tolerances, the overall condition of your vehicle’s unibody chassis may or may not affect the ease of installation. Due to general wear and tear or high horsepower chassis flex or accident, the installation can be very difficult. Please read our instructions before purchasing. Be prepared, you will have to remove your shocks from the car to get the bar in and modifications may be required. The tight clearances may also scratch up your engine bay paint during installation. If you cannot get the bar to fit, please email us. BUT WE CANNOT TAKE BACK ANY BARS THAT HAVE BEEN PAINTED OR MODIFIED. SO TEST FIT FIRST! DOWNLOAD INSTRUCTIONS HERE Rear strut tower bars also available here.

Circuit Hero Steering Wheel Hub Adapter V2
Circuit Hero Steering Wheel Hub Adapter V2
$199
The Circuit Hero Billet Steering Wheel Hub is machined out of a single solid piece of 6061-T6 aluminum. There were no shortcuts in the creation of this hub. At 3" tall, our hubs will still work great with quick-releases or hub extenders. This will be the easiest steering hub you will ever install on your car! Removal of the factory SRS "clockspring" and harness is not required. Your SRS clockspring is retained in case you ever want to revert back to a factory steering wheel. This means that you can keep the factory horn and cruise control wiring intact. Your factory horn wire will go right into the aftermarket horn button! A resistor is also included to keep that pesky SRS airbag light from lighting up on the dash cluster. Note: you can run this hub without the SRS clockspring too, but you will lose horn functionality.  Each hub has two bolt patterns to fit both of these 6-hole pattern steering wheels:  6 x 70mm (Circuit Hero, Momo, Sparco, OMP) 6 x 74mm (Nardi, Personal) FEATURES: Crafted From Solid Billet Aluminum Includes 1 SRS Light Resistor, 6 Countersunk Allen Bolts Available in Silver with Clear Anodized or Black Anodized APPLIATIONS: EG Civic EK Civic* DC2 Integra *Made specifically for the EK chassis but can fit these other vehicle applications below. If your car has a dual stage airbag you may need two resistors instead of one. 2002-2006 Acura RSX (DC5) 2004-2008 Acura TSX - (Horn not compatible) 1994-1997 Honda Accord 1998-2002 Honda Accord 2001-2005 Honda Civic (all) 2007-2009 Honda Fit 1997-2001 Honda Prelude 2000-2009 Honda S2000 **FOR OFF-ROAD USE ONLY Installation Guide / Product Specs
