YCW Suspension

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
  • 4mm Rebound Adjustment
  • - Our Reference Series Coilovers allow up to 4mm of Rebound Bleed Adjustment, 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 coilovers on the market, we do not determine our adjustment range by "number of clicks" but rather, how much bleed is used i.e 4mm bleed = minimum Rebound Force. 0mm bleed = maximum Rebound Force. Typically, it takes at least 0.5mm of bleed to "feel the difference" between adjustments
  • 44mm OD Forged 7075-T6 Hard Anodised Aluminium Double-Digressive Piston
  • - Our Double-Digressive Piston is over-engineered for superior strength, with anti-stiction and anti-friction properties
    - At lower shock speeds (Cornering), our Double-Digressive Piston maintains a higher damping force, offering increased responsiveness and stability
    - At higher shock speeds (Bumps), our Double-Digressive 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 allow you to precisely set the amount of required bump travel according to your vehicle modifications
    - Ride Height is not adjusted by the lower mount; it is adjusted by the spring perch
    - As Swift Linear springs are used, spring rates do not change when pre-loading the spring; that only applies to non-linear springs
  • Weather-proof Neoprene Shock Covers
  • - High Quality Weather-Proof Shock Covers, preventing water and dirt from clogging up the shock assembly
  • Fully Rebuildable
  • - Our Reference Series Coilovers are fully rebuildable, with spare parts always in stock and available for purchase directly from one of our local service facilities
