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

THIS STUFF WORKS!!!!!!
First of all - RUN, DON’T Walk & get this. IT WORKS!!! I kid you NOT, that I can literally feel sprouts of hair growing out of the roots of my head! After washing my hair And drying it, I part my hair into several sections and gently massage it into my scalp. After at least a day or so, I can feel the tickle in my scalp, it feels like grass slowly growing. I have plenty of hair, but I would love to actually see this product used on someone who doesn’t have hair like me. I am using the product because of a thinning spot that I have from a sew-in that I have had multiple times, and getting it parted in the same area for over a period of time. You can Not beat this product, especially for the price.

Don't not purchase!!!!
Color: A
This is product has over ingredients, its made in China and the shelf life is 3 years! No naturall product has a shelf life of a 3 years or any storing instructions. Just an FYI when buying any product, the ingredient that's the most in the product is the first on this list of ingredients WATER is the first, Batana Oil is second to the last. the packaging say 100%, 100% what? Its truely not Batana Oil. I am sending this back ASAP and working on my own mix for my hair growth. I am dealing with scared alopecia and have been searching for things to help with my hair growth. I am tried of companies thinking they will take my money. I was not able to see the ingredients until I recieved the package, which is not a terriable way to sell a product.

We love this stuff
Color: A, Color: A
My baby had an infection in his hair that he got once he started daycare. We tried everything to kill the fungus. It got so bad I had to take him to the doctor and they finally gave him some antibiotics and medicated shampoo. His head was so sore and tinder he didn’t want anyone to touch his head. So imagine trying to wash his hair everyday. The shampoo killed the fugus and took his hair out where it was. I purchased this product. IT REALLY WORKS!!!!!! We’ve been using it a few weeks and we definitely see a difference.
P.S I went and purchased the whole set

I like it
Color: A
I'm unsure how it affects hair growth since I've only had one jar. It does leave hair moisturizedand soft. It has a really nice scent.

Love this product!
Color: A
This really keeps the hair moisturized. Don’t use it too much because it causes build up. You can use as a conditioning treatment and wash it out or you can use it as a moisturizer.
