TRACK-BRED ENGINEERING MEETS STREET REFINEMENT – PROFESSIONALLY CONFIGURED BY UNLIMITED WORKS.

The Unlimited Works Original Öhlins DFV Coilover Suspension represents the culmination of extensive track experience and meticulous setup expertise.

By combining the exceptional chassis of Öhlins DFV dampers with carefully selected spring rates and Unlimited Works’ proprietary damping force configuration, these coilovers deliver a level of performance that transcends conventional off-the-shelf suspension – offering both daily-driven comfort and circuit-ready capability in a single package.

Product Highlights

🏆 UNLIMITED WORKS PROFESSIONAL CONFIGURATION
These are not merely Öhlins DFV dampers – they are Unlimited Works-configured systems:

• Öhlins DFV dampers with proprietary Unlimited Works damping force settings

• Race-proven Bestex or Hyperco springs

• Application-specific tuning developed through extensive track experience

• Configurable for street comfort or circuit attack

⚙️ COMPLETE LINEUP BY CHASSIS

🔄 EVOLUTION X – REAR LONG-STROKE VERSION AVAILABLE
The Evolution X features advanced electronic controls and a factory setup optimized for maximum contact patch. While previous generations rarely required increased rear stroke, the Evo X may benefit from stroke enhancement. A rear long-stroke version is available for those seeking additional travel.

Note: Unlimited Works’ demonstrator vehicle does NOT use long-stroke configuration, as roll control is prioritized and no traction loss due to insufficient stroke has been encountered.

🔧 COMPREHENSIVE CUSTOMIZATION OPTIONS

Spring Rate Customization:

• Standard rates provide multi-purpose usability – neither too firm for street nor too soft for circuit

• Street-focused: Reduce rates by 2kg front/rear

• Circuit-focused: Increase rates by 2kg front/rear

• Target-specific setup available (e.g., “under 1 minute at Tsukuba,” “under 20 seconds at Suzuka”)

Rear Upper Mount Options (Same Price):

• Pillowball Upper Mount: Standard – maximum precision

• Rubber Upper Mount: Optional – prioritize ride comfort, noise reduction, and mount longevity

Circuit SPEC Available:
Purpose-built for serious track use with Tsukuba SPEC1/SPEC2 options available at same price

Technical Specifications

Dampers

• Base Unit: Öhlins DFV (Dual Flow Valve) technology

• Configuration: Unlimited Works proprietary damping force settings

• Adjustment: Full length adjustable – ride height and preload independently adjustable

• Surface Finish: Current production features silver outer case finish

Springs

BESTEX:

• Racing industry standard with proven track record

• Characteristic: Excellent initial response, firm support

• Preferred for: Sharp steering response characteristic of Lancer Evolution

HYPERCO:

• Alternative high-performance spring option

• Characteristic: Superior initial compliance, supple feel

• Preferred for: Enhanced ride quality without sacrificing performance

Construction

• Type: Full length adjustable – preload and ride height independently configurable

• Preload Adjustment: Can be adjusted independently of ride height – actively utilized by experienced racers

• Durability: Engineered for Evolution chassis weight and rigidity – higher rates pose no issues

Performance Characteristics

🏎️ UNMATCHED ROAD HOLDING & GAP ABSORPTION
The Unlimited Works Öhlins DFV configuration delivers:

• Superior surface tracking: Exceptional road-following capability

• Gap absorption: One-stroke settling over bumps – no secondary oscillation

• Example: Tsukuba 1000’s final corner “washing board” section – settles in a single stroke without flutter

⚖️ BALANCED ROLL CONTROL WITH TRACTION

• Appropriately controlled roll without sacrificing ground contact

• Wide wheels (10.5J) and tires (295/35-18) accommodated without suspension flutter

• Visual comparison demonstrates superior roll management versus conventional coilovers

🔊 RIDE QUALITY NOTE
Spring rate alone does not determine ride comfort:

• These 14-16kg configurations can feel more comfortable than other manufacturers’ 12kg setups

• The inherent quality of Öhlins DFV damping combined with Unlimited Works tuning transcends simple spring rate numbers

スプリングはベステックス製を使用。強い足を作るには不可欠な存在。
レートは比較的高めだが、ランサーのボディ剛性、車重から全く問題ない。
※乗り心地はスプリングレートにさほど依存しない。
