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

Good purchase
Style: 3 Pound, Pair
These are just the right weight for me to start gaining muscle back in my arms, after a large weight loss. They are of good quality, they are covered in a nice rubber like coating that is soft to the touch. They are small enough that i can take them with me when I travel. My dog has got hold of them a couple times and played with them, and they held up just fine without any damage.

Solid, grippy, and they don’t roll away!
Style: 10 Pound, Pair
I bought these because I’m finally trying to build a consistent home workout routine and didn't want to drop a fortune on name-brand weights. I’ve been using this 10lb pair for about a month now for everything from overhead presses to lunges, and honestly, they’re exactly what I was looking for. The Pros: • That Neoprene Grip: The coating is fantastic. Even when my hands get pretty sweaty halfway through a workout, I don’t feel like I’m going to drop them. It’s a much "softer" feel than cold metal or hard plastic. • The Hex Shape: This is a small detail that makes a huge difference. Since the ends are hexagonal, they don't roll across the floor when I set them down between sets. They also stay put if I’m using them for "renegade rows" or floor work. • Compact Size: They aren’t bulky. I can easily shove them under my bed or in the corner of the closet when I’m done. • No Weird Odor: I was worried they might smell like a tire factory (which happens with some rubber-coated weights), but these had almost no scent right out of the box. The Cons: • Handle Diameter: The handles are a little on the thicker side. I have medium-sized hands and it’s fine, but if you have very small hands, they might feel a bit chunky to wrap your fingers all the way around. • Color Scuffs: The navy blue looks great, but if you clank them together or drop them on concrete, the coating can scuff or show dust pretty easily. The Verdict: If you just need a reliable set of weights for HIIT, Pilates, or general strength training, these are a no-brainer. You're basically getting gym-quality equipment for a fraction of the price. I’ll probably be back for the 15lb set in a few months!

Cozy, put you'll need to clean your washer and dryer
Size: 35 in
My dogs LOVE this bed. It's plush, comfy and cozy. Downside, washing and drying it even on cold and low settings - the black backing sheds and covers the inside of washer and dryer. It's easy enough to do. I've washed them twice now and has happened both times.
