Fortune Auto has established itself as a premier manufacturer of performance suspension systems that bridge the gap between street comfort and track capability. The company produces hand-built kits designed to suit various driving applications, from daily commuting to competitive motorsport. When upgrading your vehicle’s handling, installing fortune auto coilovers allows for a level of customisation, rebuildability, and technical precision that distinguishes them from mass-produced alternatives.
The name Springrates is synonymous with suspension expertise and serves as a vital resource for those seeking to understand spring rates and technical tuning. Fortune Auto coilovers combine digressive piston technology, modular construction, and premium materials to deliver adjustable systems tailored to specific vehicle models and driver preferences. This guide examines the technical specifications and design features that define Fortune Auto’s approach to suspension development, from material choices to BMW-specific applications.
The following sections detail the engineering solutions employed across their product line, including the use of synthetic shock oil, anodised aluminium components, and bearing mount systems that influence steering response and overall vehicle dynamics.
1) Fortune Auto 500 Series Coilovers
The Fortune Auto 500 Series represents the entry-level option in the Fortune Auto lineup. These single adjustable coilovers utilise a High Flow Digressive Piston design to balance performance handling with everyday comfort. As a leading retailer, Springrates provides the full range of Fortune Auto 500 series suspension for enthusiasts looking to improve their car’s stance and cornering ability.
Each 500 Series system is hand-built to maintain strict quality control standards. The design is inherently modular, allowing for future upgrades and complete rebuilds, which significantly extends the product’s usable lifespan. The dampers feature adjustable settings that drivers can modify based on their preferences, letting users fine-tune their setup for different driving conditions.
2) Fortune Auto PRO 2-Way Generation 8 Coilovers
The PRO 2-Way Generation 8 represents Fortune Auto’s double adjustable damper system. This coilover features separate compression and rebound adjustments, allowing drivers to fine-tune their suspension characteristics independently. The system utilises Concave Flow Digressive Piston technology, providing a wide adjustment range whilst maintaining consistent damping performance.
Fortune Auto designed the Generation 8 with aluminium components that reduce weight without sacrificing structural integrity. The back-milled construction ensures optimal efficiency in both performance and weight distribution. Furthermore, the modular architecture allows owners to send their suspension back to the factory for upgrades to higher specification configurations as their needs evolve.
3) Flow Digressive Piston Technology
Fortune Auto coilovers employ digressive piston technology as a core component of their damper design. This technology distinguishes their suspension systems across multiple product series. The digressive piston works by providing stiff low-speed compression and rebound forces, which translate into improved control over body movements like roll, dive, and squat.
At higher shaft speeds, the damper behaviour changes. When the suspension encounters bumps at speed, the digressive valve allows forces to “blow off,” creating a more compliant response that maintains mechanical grip. The 500 Series utilises High Flow Digressive Piston technology, whilst the 510 and Dreadnought lines feature the more advanced Concave Flow Digressive Piston.
4) Modular and Rebuildable Design
Fortune Auto engineered its coilover systems with modularity as a core principle. Each component can be independently modified, replaced, or exchanged. This rebuildable construction allows owners to service their suspension without purchasing entirely new units.
The modular architecture enables upgrades to higher-specification variants. Owners can send their 500 Series coilovers to be converted into 510 Series or Dreadnought PRO systems. This design approach extends the lifespan of the investment and reduces long-term ownership costs.
5) Aluminium Components with Bright Dip Anodising
Fortune Auto applies bright dip anodising to their 6061 forged aluminium components. This process combines chemical polishing with anodising treatment, enhancing the structural integrity of the material while creating a protective layer that resists corrosion and oxidation.
The treatment produces a polished surface finish that is both functional and attractive. Because 6061 aluminium alloy is used, the anodised coating helps maintain the components’ condition over extended use, protecting critical parts from salt, moisture, and road debris.
6) Radial Bearing Mounts for Steering Precision
Fortune Auto integrates high-quality Koyo Japan radial bearings into its systems as standard equipment on MacPherson strut applications. These bearings allow the camber plate and piston shaft to rotate independently from the coilover assembly during steering inputs.
The radial bearing design reduces binding, which translates to smoother steering response and more consistent feedback. It also eliminates approximately 95% of the noise typically associated with camber plates on strut vehicles by isolating spring movement from the rest of the assembly.
7) Custom Coilover Systems for BMW Models
Fortune Auto produces custom-built systems specifically engineered for BMW vehicles, including the M2, M3, and M4 models across multiple generations. They also support the G20 3 Series in all-wheel-drive configurations with direct-fit applications.
The Dreadnought PRO series offers advanced adjustability for BMW enthusiasts seeking track-focused performance. All BMW-specific kits feature modular construction and are manufactured to vehicle-specific requirements, typically requiring a four-week lead time for the bespoke build.
8) High Flow Synthetic Shock Oil
Fortune Auto coilovers utilise high-quality synthetic shock oil. Synthetic oil offers superior thermal stability compared to conventional mineral-based fluids, meaning damping characteristics remain consistent across a wider temperature range during spirited driving.
Fortune Auto specifically uses Amsoil synthetic shock oil in certain product lines. The high flow properties allow the oil to move efficiently through the internal valving, contributing to the responsive feel and precise control for which the brand is known.
9) Premium Chrome Silicon Springs
Fortune Auto equips its Generation 7 and Generation 8 lines with premium chrome silicon springs as standard. These springs are manufactured in the USA using a specialised alloy formulation that provides enhanced durability.
This alloy composition helps maintain consistent spring rates over extended use and repeated compression cycles. Replacement springs are available in various ratings, typically ranging from 4k to 16k, allowing users to further customise their spring frequency.
10) Adjustable Rebound and Compression Settings
Depending on the series, Fortune Auto coilovers offer varying levels of damping adjustment. Entry-level systems feature single adjustable dampers, while the Dreadnought PRO 3-Way dampers offer the highest level of tuning, separating high-speed and low-speed compression adjustments.
The adjustment range is significant; drivers can transform their vehicle’s handling from comfortable street settings to track-ready firmness. This flexibility ensures that the suspension can adapt to the specific needs of the driver and the terrain.
