Generation-Specific Notes
NA (1989-1997)
- • Softest springs from factory - biggest improvement potential
- • Bilstein shocks are popular OEM+ upgrade
- • Double wishbone front suspension - excellent geometry
- • Chassis flex more noticeable - bracing helps significantly
- • Lightweight - suspension changes have bigger impact
NB (1998-2005)
- • Stiffer chassis than NA - less need for bracing
- • Sport package (2001+) has better factory suspension
- • Same mounting as NA - most parts interchange
- • Bilstein shocks available from factory on Sport models
- • MSM has unique suspension components
NC (2005-2015)
- • Multilink rear - more complex than NA/NB
- • DSC/ABS integration - affects wheel speed sensors
- • Heavier car - needs stiffer springs than NA/NB
- • Club/Grand Touring packages have sport suspension
- • More limited coilover selection than NA/NB
ND (2015+)
- • Most advanced factory suspension setup
- • Bilstein dampers standard on Club/RF models

Installation & Setup Tips
Professional Tips
Tools & Preparation
- • Spring compressors - essential for safety
- • Torque wrench - proper specification critical
- • Jack stands - never work under car on jack only
- • Alignment after - mandatory after suspension work
- • Break-in period - 500 miles before final adjustment
Setup Guidelines
- • Start conservative - softer settings first
- • One change at a time - track what works
- • Corner balance - crucial for coilover setups
- • Tire pressure - affects suspension feel significantly
- • Document settings - write down what works
