OVERVIEW
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 is:
1) Designed and Engineered in the United Kingdom by British Engineers
2) Offers a 100% Bespoke solution, at an affordable price point
3) Offers premium features and technology that is applicable to real-world applications
4) Utilises premium quality service components (i.e Valving, Oil Seals, Damper Fluid, Bushings and Springs)
5) Offers local (North American, European and Asian) facilities for rebuild and servicing
6) All new customers are offered their first Dyno Tune free-of-charge, with a 50% discount on revised Spring Rates
7) Fully upgradeable to our more competition-orientated 2-Way and 3-Way Coilover Kits
Please do not compare our mid-range coilovers to the multitude of Taiwanese budget coilovers currently available as that is not our intended market segment, and our higher pricing reflects this. However, at only marginally more cost than a European/Japanese brand budget setup, you get a higher quality, better performing, British-Engineered, 100% Bespoke coilover solution with an
industry-leading warranty
, unparalleled after-sales technical support and multi-national product servicing. Due to the nature of a customised product,
we currently have a 1-2 week assembly lead time
. None of the coilover kits we supply are off-the-shelf.
SPECIFICATIONS
Forged 6061-T6 Hard Anodised Aluminium Front Upper Mounts
- Strong and Lightweight, our Forged Upper Mounts are Hard Anodised for superior Corrosion Resistance
Forged 6061-T6 Hard Anodised Aluminium Rear Upper Mounts (Where Applicable)
- Strong and Lightweight, our Forged Upper Mounts are Hard Anodised for superior Corrosion Resistance
High-Tensile Carbon Steel Front Camber & Caster Plate with Anti-Slip Coating
- 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 OEM-Style Thrust Bearing
- Strong and Lightweight, our Forged Upper Spring Perches are Hard Anodised for superior Corrosion Resistance
- High Quality Sealed OEM-Style Thrust Bearing removes rotational stress from the upper mount and is sealed from the elements
- Unlike our competitors that use regular Radial Ball Bearings, our Thrust Bearings rotate in parallel to the upper mount and will not cause catastrophic chassis damage should it fail
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
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
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
9-Level Rebound Adjustment
- Our Reference Series Coilovers allow 9 levels of Rebound Adjustments, allowing you to fine-tune your vehicle comfort and handling
- Proprietary Bleed Needles and Jet Valves from the USA are used which significantly increases fluid control sensitivity between adjustments
- 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
Sandvik 20C Carbon Steel Shims
- Only the finest Swedish Sandvik 20C Carbon Steel Shims are used, which are specifically designed for use in shock absorber valving
- Offers superior fatigue strength over the cheaper Taiwanese spring steel shims which lose their elasticity after only 12 months of normal use
- Offers superior surface finish and dimensional tolerances, increasing fluid control sensitivity and smoothness
- Although 10 times the cost of the cheaper Taiwanese spring steel shims, these premium shims ensure the consistency of our valving over extended periods
- All coilovers include a custom shock dyno graph
Silkolene PRO RSF 2.5 Damper Oil
- A proprietary formula providing consistent damping over a wide temperature range and superior anti-stiction/anti-friction properties with the highest Viscosity Index (VI-460) of any damper oil currently on the market. This British lubricant is the best performing damper fluid on the market today, as used standard by both Penske and Ohlins
Viton Performance O-Rings
- Upgraded O-Rings offering better performance and durability than lesser-quality Rubber O-Rings
Nitrogen Pressure Schrader Valve
- Allows convenient loss-free fine-tuning of Nitrogen Pressure
- Gone are the days of using a Nitrogen Needle + Self-Healing Rubber, which are prone to leaking
High Tensile Carbon Steel Lower Spring Perch Locking Collar
- Strong and Lightweight, our Forged Locking Collars are Zinc Coated for superior Corrosion Resistance
- 1pc Locking Collars, providing secure and hassle-free adjustments
Fully-Threaded Forged 6061-T6 Hard Anodised or High-Tensile Carbon Steel Lower Mount
- Threaded Lower Mounts allows us to use a longer shock body for increased performance
- Shock Stroke is unaffected by Ride Height changes
- Allows an increased Height Adjustment range
Weather-proof Neoprene Shock Covers
- High Quality Weather-Proof Shock Covers, preventing water and dirt from clogging up the shock assembly

WHY CHOOSE YCW SUSPENSION?
Proud to be British
Established in 2010, YCW Suspension, in partnership with Swift Springs, is the accumulation of over 15 years experience in the performance suspension industry, with our roots stemming back to the mid 1990's and the then adolescent import market. Recognising the growth potential of what is now a multi-million dollar industry, and the lack of grassroots friendly manufacturers, our aim and reason for being is to offer a cost-efficient and new-age customer-orientated alternative to the more traditional performance suspension specialists.
What was once in the realm of high-profile racing teams and car manufacturers; and only a dream for the grassroots, is now available to the everyday consumer thanks to our Full-Service capabilities and Multi-National facilities in the United Kingdom (Head Office & European Market), United States (North American Market) and Hong Kong (Asia-Pacific Market). Our UK Head of Operations and Lead Engineer, Stephen Brindle, has extensive chassis dynamics experience gained while working with M-Sport and several other WRC Rally Teams.
In only a few short years, YCW Suspension has positioned itself as one of the leading global manufacturers and distributors of 100% Bespoke suspension solutions, with Swift Springs quickly establishing itself as the leader in performance coil springs. From initial contact, through to the final product, we have the knowledge and expertise to fulfill all of our clienteles requirements. What's more, unlike with our more traditional competitors, our clientele will not experience the drawbacks of communication and servicing commonly associated with third-party distributors; all of our first-line point of contacts, from sales to technical, are Western-Educated with fully fluent linguistical capabilities in English, French, Spanish, Japanese and Chinese. In short, YCW Suspension can offer you unparalleled expertise in Bespoke Chassis Development.
Although there are a lot of mass-market (i.e budget) coilovers available, they are basically all the same/similar design (i.e generic) and have not changed over the past 15 years. Infact, the top selling mass-market Taiwanese Coilovers that are currently plaguing the market at the moment are all manufactured from the same technical drawings originating from BC Racing!
In this day and age, it is indeed very simple and cost effective to have basic structural components (i.e Hard Parts) manufactured from Aluminium or Steel. Provided basic manufacturing standards are adhered to, there is no difference in quality between an Aluminium or Steel component manufactured in the USA than one manufactured in Taiwan. Unfortunately, whilst the hard parts are often of sufficient quality, the nature of mass-market manufacturing often means poor quality service components being used (i.e Wear parts, such as Shims, Oil Seals, Damper Fluid, Bushings and Springs), a lack of proper quality control during damper assembly and, more importantly, a generic off-the-shelf Valving Profile that was not tuned for your specific vehicle parameters. For example, a 6K Valving Profile for a Honda Civic EP3 should
NOT
be the same as a 6K Valving Profile for a BMW E92 335i. A lot of coilover manufacturers, including the budget & mid-range offerings from some of the top European & Japanese brands, will all use the same generic 6K Valving Profile between different vehicle applications. Why? Because either they lack the specialist equipment and knowledge required to custom-tune their dampers themselves, they are trying to keep development costs down, or their manufacturing is outsourced to a mass-market Taiwanese manufacturer (whom also lack the aforementioned).
In summary:
1) Research the design (not Aesthetics) and feature set, and whether it is applicable in a real-world application
2) Research the quality and brand of ALL service components being used. Coilover A may look like Coilover B, but can be completely different internally
3) Confirm the left/right Spring Rates are matched, and that all 4 corners supplied are as advertised
4) Confirm the Valving Profile of the dampers are for the vehicle in question, and not just a generic Valving Profile based on Spring Rate only
Of course, we fully understand that the majority of customers are budget constrained, and those who are not generally prioritise brand over value. It is because of this, we at YCW Suspension 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, the aim with our mid-range 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 a 100% Bespoke solution at an affordable price point without sacrificing on technical support and servicing.
Please do not compare our mid-range coilovers to the multitude of Taiwanese budget coilovers currently available as that is not our intended market segment, and our higher pricing reflects this. However, at only marginally more cost than a typical European/Japanese budget setup, you get a higher quality, better performing, British-Engineered, 100% Bespoke coilover solution with an
industry-leading warranty
, unparalleled after-sales technical support and multi-national product servicing.
