How to Adjust Coilover Suspension?

[DeAubrey]

Adjustment methods for coilover suspension: 1. Set the stiffness to maximum hardness, then drive the car on the road to feel the suspension's feedback. If the road test feels too hard, adjust it one or two notches softer until you find the comfortable setting for yourself; 2. Then adjust the compression and rebound bidirectional settings, similar to the stiffness setting, starting from the hardest setting for road testing; 3. Next is the rebound damping. Under safe conditions, quickly take corners to feel the roll angle, setting the damping at the softest position. If during the road test you find the roll angle too large, increase it by two to three notches. If it reaches the limit, then reduce it by one to two notches.

Last time I spent a whole day adjusting my coilovers myself, and the key was preparation: first find a level ground, jack up the wheels to suspend them, then loosen the locking rings on the spring seats. When turning the spring base to adjust the height, remember to use a ruler to measure the distance from the tire to the wheel arch. After each adjustment, lower the car to test—if the body is too low, it will scrape the chassis. The damper usually has a knob; turning it clockwise makes it stiffer, which is stable in corners but bumpy; counterclockwise makes it softer, more suitable for daily driving. After adjusting, you must drive a few kilometers to test different road conditions—if it bounces too much over speed bumps, you’ll have to redo it. Finally, don’t forget to use a torque wrench to lock the locking rings, or they’ll squeak on bumpy roads—I learned this the hard way.

Adjusting coilovers focuses on three core aspects: ride height, spring preload, and damping settings. The professional procedure involves lifting the vehicle, removing the wheels, loosening the spring lock nuts, and rotating the threaded collars with a specialized wrench. For every 5mm height adjustment, the car must be lowered to check actual stance - shock absorber travel should never bottom out. Spring preload is critical; I recommend leaving 3mm clearance to prevent rattling noises. The damping adjustment knob is located atop the shock body - start testing from the softest setting during road tests, only increasing stiffness after achieving smooth performance over road imperfections. Always perform a four-wheel alignment to adjust camber angles afterward, or all your efforts may result in uneven tire wear. Keep a logbook to record each parameter change and compare handling differences systematically for optimal efficiency.

Adjusting coilovers for daily driving isn't actually difficult. First, clarify your purpose: lower the car for stance, or focus on softening damping for comfort. Prepare necessary tools like a shock wrench and measuring tape, jack up the car and loosen the locking collars, then adjust height by rotating the threaded base. Remember to adjust all four wheels simultaneously, measuring fender height differences after each 3mm adjustment. Don't randomly turn the damping knob - the middle setting is most balanced by default; if bumps feel harsh, turn counterclockwise 1/4 turn to soften. Key checks: ensure springs are properly seated, add preload if shock bodies wobble when shaken by hand. After adjustment, test drive on mixed road surfaces - if steering feels heavy or bouncing occurs, fine-tune accordingly.
