K2 Pro-Circuit 2-Way Coilovers are designed for cars looking to set track records and leave with 1st place finishes. All K2 Pro-Circuit 2 Way Coilovers feature 12 way dampening and rebound adjustment.  They come with stronger internals to handle all the abuse you can throw at them. Stiffer spring rates and more aggressive valving is set on K2's to keep the car stable in the corners. To make sure they will handle lap after lap we've paired up with Swift Springs to offer our own custom spring for all K2's. They all feature pillow ball upper mounts including older vehicles with double wishbone suspension.

Our goal was to design a suspension setup that is reliable race coilovers built with the best components.  All setups feature adjustable ride height and 12 way dampening and rebound to adapt the ride to your preference. K2 Pro-Circuit 2-Way have remote reservoir and rebound adjustment to further adjust and setup the car to your driving style. 

Starting with the strut, we invested a lot of time to ensure that they are both durable and reliable. We start with a durable heat-treated steel piston and needle valve to ensure proper travel and linear compression ratio. The strut body is designed to handle the heat and the life cycle it will be put through. Each strut is filled with proprietary oil that is designed to maintain its viscosity even under increased heat or abuse. The oil will keep its unique properties over the years to maintain that same ride quality. This is crucial to the quality and longevity of the strut. Poor quality suspension setups use cheaper oil that can become frothy, lose its strength and degrade overtime. These inferior suspension systems will lose their fluid movement and/or become too soft. We finish the strut piston with longstanding, high-heat rated double seals that are designed to take abuse without breaking a sweat, literally. No leaking struts here. The strut is the most important part of any suspension system. It determines the ride quality and the overall feel. We do not just use a stiffer spring at the suspension to compensate for a poor quality strut; instead we made sure to start from scratch and build a complete coilover that will differentiate itself from the rest.

Next we pair the struts with a high-tensile strength Swift Spring that is designed to last without sagging or premature wear. Swift Springs have proven themselves to last longest into a race without fatiguing. Springs are tested to ensure there is no coil bind and full range of motion. The high quality strut and dampening allows us to use the proper spring rates needed for each setup that will complement the adjustable dampening rates. Each spring is mounted on adjustable aluminum perches that can be used to adjust preload and travel. Incorporated washer and spacers are in place to keep the system free moving especially on McPherson style struts.

The coilover system is finished with a combination of powder coating, electroplating, and anodizing to give it a great look and protect it. McPherson style struts feature adjustable upper camber plates and pillow ball mounts.
Applications: 
  • 02 - 06 RSX 
Valve:
K2 Race Valve - This is our standard linear valve. Damper will get stiffer as the strut travels through its range of motion. This can give some harshness with very aggressive curbs.

K2 DS1 Valve - This is our hybrid valve. We took some characteristics from the Race Valve and our Digressive Valve to give a good mix of both. The damper is a great option for someone driving their car to the track.

K2 TD1 Valve - This is our Digressive Valve which offers the best overall performance. It will have a stiff lead in and very predictable compression throughout the range of motion. This would be the valve currently used on James Houghton's GLTC TSX and Chris Boesrma's Track MOD Civic.

Note: 
Springs rates can be changed +/- 4K (up or down).
Recommended Spring Rates: F-18K / R-20K

Best shoe ever
5 star rating for literally the best shoe ever. I wore these almost everyday this summer. They are so incredibly comfortable. Cushion and padding is wonderful makes walking and wearing them very easy. They are not to platform at all and they don't have a separate heel height from the rest of the shoe so you're on a even walking ground. Size is perfect I stayed true to size and ordered my original sizing in Ugg which is perfect. The style os so trendy and literally goes with everything. I highly suggest them. I have back problems/ back surgery and these made my life so much easier. Comfortable and great support.

Well made sandals
Nice sandal that works well for me, feet sit comfortably in the shoes. I’m a quadriplegic that needs someone to wrestle my legs while putting my shoes on for me. These go on fairly easily. I have short legs and the extra height of the sandals helps to reduce the pressure on the back of my legs while my feet are on the legrests. Also my ankles tend to buckle and cause my feet and shoes to roll over onto the side of my foot. The soles of the UGG Goldenglow are wide and flat, substantially reducing this tendency. As far as comfort and function while walking, I can’t speak to that.
