Default YCW Reference Series Coilovers for 1/3/5-Series - Sponsored Drivers Required - 12-14-2015, 11:03 AM

Hey Guys,

after researching the various coilover setups currently available on the market, we've noticed there is a gap in the market for a setup that is:

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

there are a lot of generic setups available on the market at the moment, however, they are basically all the same/similar setup (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)

of course, 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 similar.

because of this "gap", we at MFactory have decided to do what we do best, and this is to provide you guys with a quality solution that meets our #1 priority; Value for Money. Whilst this new project is still in it's infancy, we want to take this opportunity to design, manufacture and offer our solution based on your feedback and not just what the "marketing folks" think you want!

so our project as it stands today:

YCW Reference Series Coilovers
- Spec'd for Superior Performance
- Priced for Affordability
- Over-Engineered for Comfort & Safety

FEATURES:

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 (MacPherson)
- CNC-Machined High-Tensile Carbon Steel supports more load than lesser-quality mounts
- Camber Angles can be adjusted precisely to your driving needs
- Where space permits (Application Dependent), Caster Angles can also be fine tuned

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

62mm ID Cold-Wound Japanese SAE 9254V Chrome-Silicon-Vanadium Steel Linear Springs
- Custom-made for us in Japan from the highest quality Japanese-grade spring steel, using proprietary manufacturing processes
- 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

62mm ID Cold-Wound Japanese SAE 9254 Chrome-Silicon Steel Helper Springs (Application Dependent)
- Optional Helper Springs can be used to increase droop travel

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

14mm OD or 20mm OD (MacPherson) 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
- Although Inverted Monotube Shocks are touted as the solution, these come with their own set of problems, not least the substantially increased cost of manufacture
- Our over-engineered solution to the problem, with only a marginal increase in manufacturing costs, is our proprietary Chromoly Steel Piston Rod
- Offering a substantial increase in tensile strength over lesser-quality rods, not only does this keep costs down, it significantly increases product safety

Oversized Piston Rod Guide
- A common issue with the majority of budget coilovers currently on the market is performance-sapping deflection and shaft-play, even after only limited usage
- Through the use of our proprietary Piston Rod Guide, this minimises deflection and shaft-play, 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 Adjustments, you can physically feel the difference between each adjustment
- In this particular case, more is not better; it's simply an inconvenience and setup-nightmare

10cm/15cm/20cm Length Adjustment Extenders (Optional)
- Designed for vehicle applications with limited access to their upper strut mounts

44mm OD Forged 7075-T6 Hard Anodised Aluminium Digressive-Blow-Off DBO Piston™
- 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

Performance Synthetic Damper Oil with High Viscosity Index and Proprietary Additives
- A proprietary formula providing consistent damping over a wide temperature range and superior anti-stiction/anti-friction properties

Viton Performance O-Rings
- Upgraded O-Rings offering better performance and durability than lesser-quality Rubber O-Rings

Forged 6061-T6 Hard Anodised Lower Spring Perch Locking Collar
- Strong and Lightweight, our Forged Locking Collars are Hard Anodised 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

PTFE-Lined Japanese Spherical Lower Mount Bushing (Eyelet Type. Optional)
- Increases shock articulation and prevents deflection
- Higher load rating for increased durability
- Minimises knocking noise associated with lesser-quality bearings

Silicone Lower Mount End Caps (MacPherson)
- High Quality Weather-Proof End Caps for MacPherson lower mounts, preventing water and dirt from entering the the lower shock body

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

Limited Lifetime Warranty on Hard Parts
- Warrantied against Manufacturers Defects
- Non-Transferable. Registration and Proof-of-Purchase Required
- Hard Parts include: Upper/Lower Mounts, Spring Perches, Locking Collars, Shock Body and Piston Rod

Limited 1 Year Warranty on Wear Parts
- Warrantied against Manufacturers Defects
- Non-Transferable. Registration and Proof-of-Purchase Required
- Wear Parts include: Bearings, Springs, Seals and Shock Internals

Local Service Facilities
- North America: San Dimas, USA. Warranty Claims and Rebuild Services available
- Europe: Leyland, United Kingdom. Warranty Claims, Rebuild Services and Revalving Services available

We currently have several "test sets" shipping out to our testers around Late January, and will be updating this thread with our results (along with the dyno graphs)

Sorry for the low quality image. Once the test sets are finished, I will upload better product images:

Wish I could do this. But between having an F34 and the Adaptive M Suspension, I doubt theres an application that would work

Based on the color choices I would say Bilstein. Old Bilstein coilovers were blue.

Something like 9k/11k would be more ideal for myself.

If I didn't have 2 sets of coilovers sitting in my garage, I would jump on these! I trust Mfactory wouldn't sell something they didn't think was a great product, let alone run it on their own cars.

I honestly have no idea. This will be my first set of coil overs. My car is a 2008 535xi, so it has the higher / softer suspension. I'm looking to drop it about 1.5" and stiffen it up to something like my old 335i m-sport suspension was. So I need some advice I guess.

Based on a few calculations, the following rates offer a neutrally balanced car (i.e same ratio as oem):

135i:

90% stiffer than stock
4K -> 224lb/in = 206lb/in at the wheel
12K -> 672lb/in = 215lb/in at the wheel

185% stiffer than stock
6K -> 336lb/in = 309lb/in at the wheel
18K -> 1008lb/in = 323lb/in at the wheel

335i:

53% stiffer than stock
4K -> 224lb/in = 206lb/in at the wheel
13K -> 728lb/in = 233lb/in at the wheel

130% stiffer than stock
6K -> 336lb/in = 309lb/in at the wheel
19K -> 1064lb/in = 340lb/in at the wheel
