K2-Circuit Coilovers are designed for cars destined for the track; whether thats 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.
Applications:
- 00-03 S2000 AP1
- 04-09 S2000 AP2
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 +/- 2K (plus/minus). If you want custom spring rates please contact us directly.

How Good is Great?
I purchased this DVD because of its' sustained superior ratings in the Sight and Sound survey every decade of the best films of all time. Obviously, there must be something very great about this movie. There is but but there are some second thoughts that plagued me along the way. First of all, I am always impressed by a film's ability to hold our attention. This is often where the skill of film editing is best appreciated. I confess that I found myself looking for some scenes in "8 1/2" to move along. This is a cerebral movie, not an action movie but there seemed to be a fair amount of redundancy. Secondly, I was surprized by the sound work on this movie. I made a quick glance at a few other reviews but didn't see any similar comments. Thus I don't know if it was just my copy. However, the sound didn't match up with the film very well at all. This gives the movie an odd appearance of being an Italian movie dubbed in Italian. Was I missing something? Finally, the message in this film, for me, was "to your own self be true" which is certainly a valid philosophy; just ask Socrates. However, it was stretched to come across as "accept me for who I am, not whom you want me to be". This message is still a valid philosophy but a bit harder for some of us to accept.
Having said all of that, let me praise the movie; (I DID give it a "5" after all). The acting is terrific; especially Marcello Mastroianni whose air of detachment fit the movie so well. The photography (B&W) was excellent, as well. The story is one of a director who has lost his own direction. As he stumbles aimlessly along supposedly putting together a film, his inteactions with others and his reminiscences give us an insight to his confusion. His world is overwhelming him and he can't figure out where to turn. He is much the victim of himself (which makes the message that much harder to swallow). As his crisis reaches its' own crisis, the movie rights itself with his discovery of his own self-awareness. Everything comes together at the end with a message of hope (primarily for the director). The beauty of the movie is how we are able to follow the character's collapse and rebirth. It is also in the way we can see the rest of the world through his own eyes. This is the sort of movie that will expand with each re-viewing. The DVD contains a second disc with information and reviews about the movie and the Director.
This is a good movie that caught me off-guard because I was victimized by too much advance hype. I understand the hype but it would have been better to discover it for myself. Discover it for yourself and it will be a movie you'll remember.

BD Version.
One of my top five films of all time. I won't speak much about the film itself, under the assumption most readers have already seen it. You can be guaranteed a fantastic film if you haven't seen this yet.
As far as the BD itself, the transfer is absolutely fantastic! The DVD version itself already had a pretty pristine transfer, but of course with the BD upgrade the resolution and detail is so much better, and of course comes loaded with extras and an accompanying booklet that is actually quite thorough and should be considered an item in itself, and not just a supplement to the disc.
I haven't watched them all, but the extras that are bundled with the film are plentiful and quite informative. Often times with extras you feel as though it is just filler and fodder (let's be honest, it usually is) but at least Criterion makes a conscious effort to make it interesting. I'd say the extras are worthwhile, and also an upgrade from the DVD version.
The biggest difference I noticed from my first viewing is that the subtitles are slightly changed from the DVD version, and also theatrically. There are probably lots of different translations, but it IS different from the DVD but not drastically. The same point is made, but just using a different delivery. Not sure how I feel about some of the changes, but I probably just got used to the previous translation.
I'm not sure where some of these discrepancies or complaints are coming from that have surfaced recently, but my copy was packaged in the special made Criterion jewel cases, NOT the cardboard ones, and of course not the actual blue ones. For a while, with some of the earlier releases, Criterion was releasing its BDs in cardboard slip case and digi-pack format which angered a lot of customers who spoke their voice and got them to upgrade to the now standard jewel cases. A good move in my opinion, but now I'm stuck with Third Man and 400 Blows in cardboard. Reportedly, you can send in the old cases to get upgraded to new ones, but it'll cost you 5 bucks each, so... I think I can live with it.

Sublime Masterpiece Is One Of Criterion Collection's Finest
This is one the Criterion Collection's best and most impressive Blu rays and one of my favourites. A defining work of cinematic genius, and crowning achievement of Italian master director Federico Fellini. The first truly "Felliniesque" of his films, a complex semi-autobiographical carnival mirror of artist as film maker, an unsurpassed portrait of the creative process, with a film within a film and dream and fantasy structure, it's difficult to understate the seminal impact on cinema. An astoundingly choreographed, highly stylized, fully realized, deeply personal work of artistic subconscious and expression. Extraordinary in all regards, filled with memorable and iconic scenes. One of the perfect films that is magical and magnetic, as compelling and entertaining each and every time. I must confess that La dolce vita is my favourite film (it's a bit more accessible) , but acknowledge 8 1/2 as the greater artistic work. This Criterion Collection Blu ray is truly outstanding. the film looks excellent, and contains great extra content, including a scholarly audio commentary that is highly recommended, three interesting documentaries, interviews, photo gallery and a fine essay booklet. An essential. All of Fellini's films are also recommended. This disc is also part of Criterion Collection's Essential Fellini box set, superb for those looking to collect a large portion of the director's works.
