• Application-specific tuning developed through extensive track experience

• Configurable for street comfort or circuit attack

⚙️ COMPLETE LINEUP BY IMPREZA GENERATION

🔧 GENERATION-SPECIFIC ENGINEERING NOTES

GDB (GD Series):

• When pursuing maximum sports performance, rear ride quality tends to deteriorate

• Rear suspension arm movement characteristics are not optimal

• Recommendation: Pillowball arms for rear section to improve geometry

• Spring Brand Character: BESTEX for initial response / HYPERCO for initial suppleness

GRB/GVB (GR Series):

• Balanced configuration for the newer generation chassis

• Optimized spring rates for weight and rigidity characteristics

VAB (VA Series):

• Due to increased weight and chassis rigidity, slightly higher spring rates provide better matching

• Rear Rubber Bushing Option Available (Same Price): For those prioritizing ride comfort and reduced cabin noise

🔄 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”)

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

Rear Upper Mount Options:

• Standard Configuration: Optimized for performance

• Rear Rubber Bushing Type (Same Price): Available for VAB – prioritizes ride comfort and reduced cabin noise

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

Springs

BESTEX:

• Racing industry standard with proven track record

• Characteristic: Excellent initial response, firm support

• Preferred for: Sharp steering response characteristic of Impreza performance

HYPERCO:

• Alternative high-performance spring option

• Characteristic: Superior initial compliance, supple feel

• Preferred for: Enhanced ride quality without sacrificing performance

Performance Characteristics

• 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

• Wide wheel compatibility: 295/35-18 tires and 10.5J wheels accommodated without suspension flutter
