K2-Circuit Coilovers are designed for cars destined for the track; whether that's circuit, time-attack, or drag racing. All K2-Circuit Coilovers feature 32-way dampening and stronger internals to handle all the abuse you can throw at them. Stiffer spring rates and more aggresive 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 coilover built with the best components. All setups feature adjustable ride height and 32way dampening to adapt the ride to your preference. K2-Circuit comes with pre-set rebound for a simple setup that can quickly be set to your driving style. If you're looking for rebound adjustability K2-Pro-Circuit 2 Way feature rebound and compression adjustment.
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.
Application:
- 17+ Civic Type R FK8
Spring Rate:
F-16K / R-14K
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 (plus/minus). If you want custom spring rates please contact us directly.
- Some light modification may be needed when installing rear. Please email to inquire before ordering.

Quality Toy
Size: 15", Style: Duck
Fun durable toy for tough chewers. Material is durable and long lasting, however can unravel with extended chewing or pulling. A favorite of our dogs. Easy to throw and toss in a game of fetch.

My grand furbaby loves this yellow duck!
Size: 15", Style: Duck
I bought this yellow duck as a gift for my grand furbaby about 2 years ago. It turned out to be his favorite toy and it lasted for quite some time. So, I have bought several of them and when I go to stay with him in the summer, I take him a brand new yellow duck. He carries it around with him and he loves it! Favorite toy!

My 13lb dog loves these! But tears them up in no time!
Size: 15", Style: Rabbit
I’ve bought many of these, in different styles. My dog knows it as “bunny”, so if you tell him to “go get bunny”, this toy (or one of the other characters we’ve bought) comes back in his mouth. He loves to chase it, play tuggy, and whip his head back and forth with the poor thing. He turns these into threads hanging on to rope in no time. You’d think they would be super durable, but they don’t surprise him very long. I can’t rate higher than a 3 star, because I think they are made well but he’s just really tough on them and I keep buying one version or another because he loves bunny. LOL

Durable & fun
Size: 15", Style: Rabbit
These are great pulls, long lasting. The rope in different parts make it interesting to your pet. My only issue is, I did not receive the gray animal I ordered. It was substituted by a brown one. I’ve owned six of these. The dogs have loved them all BUT neither of them will touch this brown one. I’ve tried several games with it. They run, take a sniff, & leave it. This one was a wasted $10.

Toughest toys around!!!
Color: Gorilla, Size: Small
After 30 years of shopping for dog toys & endless nights of sewing them back together, those days are over thanks to this brand of toys!
These get taken outside where they are brutally tugged, twisted, snatched, tossed and shaken to no end by our 58lb black mouth cur & 80lb Shepherd Retriever mix.
Most times they bring them back in the house but 2 of them they keep outside in the scorching Florida sun & rain & they're still tough as can be! The only damage these 2 toy punishers have managed to do is occasionally kill a squeaky inside (after about a year or more) & eventually the ones they will keep outside they have managed to get the black trim piece that goes around the outside edge to come off in a small section but it's still hanging on the toy flapping around smacking them in the face (which our black mouth cur love's,lol).
I first bought 2 small ones (yellow duck & pink pig) Christmas 2020. They held up so well that a few months later I bought the fox, dog & purple gecko. We also have the gorilla, snake, green gator (their favorite right now), orange gecko, a 2nd duck, raccoon & a few others I can't think of right now. The glorious thing is I haven't had to sew a single toy in over 2 years & I don't have to worry about my girls getting too rough with them when playing & the best part is not having to worry about them defluffing them & ingesting it or choking on it especially when I'm not at home. I don't have to pick them up before leaving to ensure they are safe. They can continue to terrorize the house playing with these even when we're not there & the only thing I have to worry about is what are they going to break when they sling one of these across the room. This brand is the only brand of dog toy we buy now. We have not had to throw any of them that we've bought away either & the cost is perfect for the value that you definitely get!
