5.1 Ride Height Adjustment (Full Length Adjustable)

The Hipermax S Series features full-length adjustability, allowing you to change the vehicle's ride height without altering spring preload. This ensures optimal suspension travel regardless of ride height.

1. Loosen the spring lock nut and the bracket lock nut using the supplied hook wrenches.
2. Rotate the lower bracket to adjust the overall length of the coilover. Turning the bracket clockwise will lower the vehicle, and counter-clockwise will raise it.
3. Once the desired ride height is achieved, tighten both the spring lock nut and the bracket lock nut to their specified torque values (50 N·m for front, 60 N·m for rear spring lock nut).
4. Ensure the vehicle is on a level surface and measure the ride height at all four corners. Adjust as necessary to achieve an even stance.

5.2 Damping Force Adjustment (30-Step)

The coilovers feature a 30-step damping force adjustment mechanism (WR Needle) to fine-tune rebound and compression characteristics. This allows for a wide range of settings from soft for comfortable street driving to firm for aggressive track use.

1. Sib id-damping force adjustment dial at the top of the front shock absorbers and at the bottom of the rear shock absorbers.
2. Turn the dial clockwise for firmer damping and counter-clockwise for softer damping. Each click represents one step of adjustment.
3. Start with a recommended setting (e.g., 15 clicks from full stiff) and adjust incrementally based on driving conditions and personal preference.
4. Always adjust both left and right sides equally to maintain balanced handling.

6. Linji Gwida Operattivi

After installing and setting up your HKS Hipermax S Series Coilovers, it is important to understand how they affect your vehicle's dynamics.

• Allinjament: After any ride height adjustment, a professional wheel alignment is crucial to ensure proper handling, tire wear, and safety.
• Stil tas-Sewqan: Be aware that lowering your vehicle can reduce ground clearance. Exercise caution over speed bumps, potholes, and uneven terrain.
• Aġġustamenti staġjonali: You may wish to adjust damping force settings for different seasons or driving conditions (e.g., softer for winter, firmer for summer performance).
