Why YCW Coilovers?

Post by YCW » Sun Feb 26, 2017 2:22 am

After countless hours of research into the various coilover setups currently available on the market, we noticed that there is a gap in the market for a mid-range setup that:

1) Offers premium real-world features, at an affordable price point
2) Offers local (North American and European) facilities for rebuild and servicing

Whilst there are a lot of generic (i.e budget) setups available on the market at the moment, they are basically all the same/similar design (i.e generic) and have not changed over the past 15 years, with prices ranging from $1000-2000; the more expensive only being due to the "brand" and the "assembled in XXX label" rather than the design features (the components are all still manufactured in China, Taiwan or Korea). Infact, the top selling Budget Taiwanese Coilovers that are currently plaguing the market at the moment are all manufactured from the same technical drawings!


Of course, we fully understand that, rather than reinventing the book, it is best to stick to tried-and-tested designs (especially for the street car) hence why all the current setups available are very similar. It is because of this gap, we at YCW Engineering decided to design and manufacture a quality mid-range solution from scratch that meets our #1 priority; Value for Money. Whilst there is a large demand for premium setups designed for the high-end race car, our aim with our Reference Series Coilovers is to bring some of the more advanced real-world features from the premium setups, incorporate them into a package suitable for the everyday street car, and offer them at an affordable price point without sacrificing on technical support and servicing

At only marginally more cost than a budget setup, you get a higher quality, better performing mid-range coilover solution with an industry-leading warranty, unparalleled after-sales technical support and product servicing

Recognising the stigma that is normally associated with Taiwanese products, a simple look below at our product specifications, manufacturing process and the advanced technology utilised in our Reference Series Coilovers will hopefully alleviate such concerns and explain why our offering is not simply just another Generic Taiwan Coilover!

Advanced Upper Mount/Spring Perch


High-Tensile Carbon Steel Front Camber & Caster Plate with Anti-Slip Coating (MacPherson)
  • CNC-Machined High-Tensile Carbon Steel supports more load than lesser-quality mounts
  • Camber Angles can be adjusted precisely to your driving needs (MacPherson)
  • Caster Angles can also be fine tuned (MacPherson)
Oversized PTFE-Lined Japanese Spherical Upper Mount Bushing
  • Increases shock articulation and prevents coil-bowing
  • Higher load rating for increased durability
  • Minimises knocking noise associated with lesser-quality bearings
Forged 6061-T6 Hard Anodised Aluminium Upper Spring Perch with Sealed Japanese Radial Bearing
  • Strong and Lightweight, our Forged Upper Spring Perches are Hard Anodised for superior Corrosion Resistance
  • High Quality Sealed Japanese Radial Bearing removes rotational stress from the upper mount and is sealed from the elements

Springs With Intellegence From Tohatsu (SWIFT)


65mm ID Cold-Wound Japanese HS5.TW Steel Linear Springs from SWIFT
  • Made in Japan by Tohatsu Spring Company, SWIFT Springs are made from the highest quality Japanese-grade spring steel, using proprietary manufacturing processes. These are the #1 Performance Coilover Spring on the market, providing an industry leading +/- 3% deviance from rated load over the entire stroke, and are backed by SWIFT's Lifetime Warranty against Spring Sag
  • Not all springs are manufactured the same. Lesser-quality, Taiwanese-manufactured springs offer inferior performance and durability
  • Although more expensive, we believe the increase in performance more than offsets the marginal increase in manufacturing costs
  • All Reference Series Coilovers are assembled with SWIFT Springs as standard, and are not just an expensive after-thought like with the majority of coilovers on the market
OEM-Balanced Spring Rates
  • The majority of budget coilovers currently on the market offer default spring rates that deviate from the oem-balanced spring rates
  • By not accounting for Motion Ratio Calculations and just replicating race-car setups, this results in a very unbalanced and uncomfortable ride on a Street Car
  • All Reference Series Coilovers are supplied with oem-balanced spring rates, offering you increased performance without sacrificing ride comfort

Advanced Damper Technology


52mm OD Cold-Drawn Japanese SAE 1020 Seamless Carbon Steel Shock Body
  • Offers superior physical properties and strength-to-weight ratio over lesser manufacturing processes
Black-Zinc Plated Fully-Threaded Shock Body with 250hrs of Salt-Spray Testing
  • Offers superior corrosion-resistance
  • All coilovers include a Salt-Spray Test Certificate
Forged SAE 4140 Chromoly Steel Piston Rod
  • Monotube shocks, although offering increased performance over Twintube shocks, have an inherent weakness; a load-bearing Piston Rod
  • Our over-engineered solution to the problem, with only a marginal increase in manufacturing costs, is our proprietary Chromoly Steel Piston Rod. We are the only company to manufacture this type of Piston Rod, and is currently used by several high-end European brands under a "transfer-of-technology" agreement
  • Offering a substantial increase in tensile strength over lesser-quality rods, not only does this keep costs down, it significantly increases product safety
  • All dampers are QC sealed with batch number and date/time of assembly
Ceramic Piston Rod Guide
  • A common issue with the majority of budget coilovers currently on the market is performance-sapping deflection, shaft-play and friction, even after only limited usage
  • Through the innovative use of our "transfer-of-technology" agreement, our advanced Piston Rod Guide, which is also used in higher-end Ferraris, significantly minimises deflection, shaft-play and friction, allowing you to reap the performance benefits for a longer period of time
7-Level Rebound Adjustment
  • Our Reference Series Coilovers allow 7 levels of Rebound Adjustments, allowing you to fine-tune your vehicle comfort and handling
  • Unlike the majority of budget coilovers currently on the market, with their 30+ Level simultaneous Compression/Rebound Adjustments, you can physically feel the difference between each adjustment, and without affecting your dampers Compression characteristics
  • In this particular case, more is not better; it's simply an inconvenience and setup-nightmare
44mm OD Forged 7075-T6 Hard Anodised Aluminium Double-Digressive-Blow-Off DBO Piston™
  • Through the innovative use of our "transfer-of-technology" agreement, our DBO Piston™ is over-engineered for superior strength, with anti-stiction and anti-friction properties
  • At lower shock speeds (Cornering), our DBO Piston™ maintains a higher damping force, offering increased responsiveness and stability
  • At higher shock speeds (Bumps), our DBO Piston™ maintains a lower damping force, offering increased comfort and control
  • All coilovers include a custom shock dyno graph
Silkolene PRO RSF VI-460 Damper Oil
  • A proprietary formula providing consistent damping over a wide temperature range and superior anti-stiction/anti-friction properties. This is one of the best, if not the best, damper fluids on the market, as used by several high-end European brands
Viton Performance O-Rings
  • Upgraded O-Rings offering better performance and durability than lesser-quality Rubber O-Rings
