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 2Way Coilovers feature 32 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 coilover built with the best components. All setups feature adjustable ride height and 32 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.
Application:
- 14-15 Civic Si (Only)
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-14K / R-12K

Overall sound thesis worthy of thoughtful consideration
Format: Kindle
Choudary’s book has the tag line, “Who wins when AI restacks the knowledge economy.” While the book is annoying in sections, vague in others, and prone to jargon in yet more locations, the basic thesis is sound and compelling. It’s worth considering.
Choudary’s main argument is that the winners after AI technology is widely adopted will be those who take a systems view of their business rather than simply upgrading individual elements within it. He backs this with several examples based on past technological disruptions and hypothetical case studies. He argues that the best advantages from AI will come from improved communication and managing risk. He supports these arguments reasonably well within the chapters. He also includes 10 Takeaways at the end of each chapter, which is extremely helpful for recapping and making sure the reader understood the thesis.
What gets annoying is Choudary goes back to the same case studies again and again and again. I reached the point of saying, “the horse is dead. Please stop flogging it.” Next, some of his arguments about things like “managing risk” are vague—there’s not enough about specific risks to be useful, which leaves AI as a magic wand to wave. Finally, as with many business writers, Choudary occasionally (but not overwhelmingly) drops into jargon like “technological solutionism.”
Overall, I recommend the book. It’s made me think, even as I struggle to apply the principles to my own business.

Must read - Insightful and Trusted
Format: Paperback
Reading “Reshuffle” was both intellectually energizing and personally relevant for me. Sangeet Paul Choudary’s work is more than just a business strategy manual, it’s a lucid roadmap for thriving amid constant change.
Having spent the past decade steering our teams through multiple waves of technological disruption, I recognized my own journey in Choudary’s stories of platform transformation. His concepts of “connectors” and “combinators” spoke directly to challenges I’ve faced: breaking down silos, fostering creative recombination of ideas, and unlocking new sources of value in our organization. There were moments while reading when I paused, reflected on recent strategy sessions, and realized how much we could benefit from the frameworks outlined here.
What truly set “Reshuffle” apart for me was Choudary’s ability to tie cutting-edge AI trends to everyday executive decisions. When he wrote about the collision between legacy content pipelines and new generative workflows, it echoed conversations I’ve had with other executives.
“Reshuffle” reminded me that constant evolution isn’t just a necessity, it’s an opportunity to lead with optimism and vision. Choudary’s voice is empathetic, insightful, and refreshingly practical, making the book feel like advice from a trusted colleague as much as a renowned thought leader.
In short, “Reshuffle” is a must-read for anyone tasked with steering a tech company through turbulent times. For me, it has become a personal touchstone for navigating and embracing what’s next.

Finally, a framework that makes sense of AI's impact on knowledge work
Format: Kindle
Most books about AI focus on task automation and productivity gains. Reshuffle does something different: it explains how AI restructures entire systems through three constraints: tasks, coordination, and risk.
For someone working in the language services industry, this book was revelatory. It helped me understand why so many conversations about AI and translation feel misdirected. We debate whether AI will replace translators when the real question is: how will AI reshuffle who creates value in language services?
Choudary's central insight is that when AI removes old constraints (like scarcity of expertise), value doesn't disappear. It migrates to new coordination and risk management challenges. This applies across all knowledge professions, not just translation.
Section 2 on knowledge work is particularly strong. It shows that lawyers, consultants, accountants, and translators are all experiencing the same fundamental transformation. We're not uniquely vulnerable; we're part of a larger reshuffling of how knowledge creates value.
If you're trying to position yourself or your organization for what's coming, this book offers the clearest framework I've found. It's not about having better AI tools. It's about understanding where value pools are forming in the new system.
Recommended for anyone in knowledge work who wants to move beyond surface-level AI discussions.

Not like any other how-to book on AI--Eric Swanson's Review
Format: Kindle
Reshuffle is not another “how to use AI” guide. It’s a powerful, big-picture look at how AI is reshaping the very foundations of the knowledge economy. Sangeet doesn’t just explore tools—he reveals the tectonic shifts in how knowledge is created, distributed, and valued. Most people use AI to improve old systems; this book shows why the winners will be those who understand and adapt to entirely new ones. Using powerful examples from history, like the bar code, container boxes and the Maginot Line, Sangeet creates powerful frames for new ways of thinking. Insightful, clear, and compelling, Reshuffle is essential reading for anyone who wants to lead in the age of AI

Would your card still be in the deck after the AI reshuffle?
Format: Paperback
AI’s impact on knowledge workers, and on enterprises, is immense. “Good enough” and inexpensive answers now abound, and the premium once commanded by knowledge workers seems to be slipping away. Enterprises are pinning their hopes on AI-driven efficiencies to stay competitive and relevant. Emotions surrounding this technological breakthrough range from doom and gloom to glee and hope.
Sangeet’s Reshuffle helps build a mental model to understand, navigate, and survive this change, and even thrive in it. It’s a refreshing departure from the usual first-order effects and fallacies that dominate social and print media.
For knowledge workers, staying relevant is becoming increasingly difficult, especially as the very definition of “relevance” evolves. Simply acquiring AI skills may not suffice if the underlying value of those skills has shifted. Judgment, systems thinking, and coordination will become more valuable. Remaining well-paid and autonomous will require protecting and growing contextual and economic value within this transformed system. Simple, but not easy.
At the enterprise level, applying AI for task-based efficiencies in one area often shifts constraints elsewhere. Using systems thinking and positioning AI as the engine, not merely a tool, for innovation and coordination across the value chain will give enterprises a fighting chance to stay competitive.
While the metaphorical pie may grow, simply “playing the same game better” won’t earn you a proportional share of it. Existing systems will be unbundled and re-bundled into offerings that solve emerging constraints. Coordinating across the value chain and taking responsibility for delivering customer outcomes will be key to unlocking outsized gains.
