Coilover Setup Guide: How to Choose and Adjust

Coilover Basics\n\nA coilover combines the spring and shock absorber into a single, height-adjustable unit. Unlike lowering springs on stock shocks, coilovers are designed to work together as a system.\n\n### Key Specifications\n\nSpring Rate - Measured in lbs/in or kg/mm. Higher rates = stiffer.\n- Street: 300-500 lbs/in front, 200-400 lbs/in rear\n- Track: 500-800 lbs/in front, 400-700 lbs/in rear\n- Time Attack: 800+ lbs/in\n\nDamping - Controls how fast the suspension compresses and rebounds.\n- Single adjustable: Rebound only (most common)\n- Double adjustable: Compression and rebound\n- Triple adjustable: High/low speed compression and rebound\n\n### Ride Height Setup\n\n1. Start with manufacturer recommended settings\n2. Measure ride height at all four corners\n3. Set corner weights if possible (cross-weight balance)\n4. Ensure adequate suspension travel\n\n### Damping Tuning\n\n- Too soft: Body roll, slow transitions, wallowing\n- Too stiff: Harsh ride, skipping over bumps, loss of traction\n- Start at 50% and adjust from there\n\n### Common Brands by Tier\n\n- Budget: Raceland, ISC, Godspeed\n- Mid-tier: BC Racing, Fortune Auto, Tein\n- High-end: KW, Ohlins, MCS, JRZ
