2. D2 shock absorber basic adjustment parameter table
| Adjustment items | Recommended range | Adjustment tools | Things to note |
|---|---|---|---|
| Body height | Front 20-30mm/Rear 15-25mm | Jack + tape measure | The height difference between left and right needs to be kept ≤3mm |
| Damping strength | Street mode 8-12 segments/Track mode 15-20 segments | Special adjusting wrench | Increase damping clockwise |
| Spring preload | 3-5mm | spring compressor | Avoid exceeding 10mm |
3. Step-by-step adjustment guide
Step 1: Preparation
Make sure the vehicle is on level ground and prepare tools such as a torque wrench (20-100Nm), vernier caliper, chassis measuring tape, etc. It is recommended to operate on a lift in a modification shop.
Step 2: Height Adjustment
Loosen the shock absorber cylinder fixing screw and rotate the spring base to adjust the height. After each adjustment, you need to drive 5 kilometers to reset the suspension system, and then measure the actual height. Data from popular forums show that 86% of modified car owners set the height setting too high for the first time.
Step 3: Damping Settings
Refer to the official recommended values:
• Urban roads: first 10 sections/last 8 sections
• Mountain road driving: first 15 sections/last 12 sections
• Track usage: first 20 sections/last 18 sections
Recent actual measurements of popular Douyin videos show that for every 5 levels of damping added, cornering roll is reduced by approximately 12%.
Step 4: Four wheel alignment
Positioning must be performed after adjustment. Recommended parameters:
• Front wheel camber angle: -1°~-1.5°
• Toe angle: 0°~0.2°
• Rear wheel camber angle: -1.5°~-2°
4. Solutions to common problems
| Problem phenomenon | Possible reasons | Solution |
|---|---|---|
| Abnormal noise when passing speed bump | The spring is not fully seated | Re-preload spring and apply grease |
| Steering becomes heavier | Front wheel height too low | Raise the front overhang 5-10mm |
| Rear wheel bounce | Damping setting is too soft | Add 2-3 levels of damping |
5. References to recent popular modification cases
According to the measured data of the "modified veteran driver" of UP station B:
• Civic FK7 street version settings: front 2-finger height/12-stage damping, 100km/h line-changing roll angle reduced by 37%
• BMW 3 Series track settings: front 1.5 finger height/18 levels of damping, track lap speed increased by 2.3 seconds
6. Precautions
1. A 20km road test is required after each individual adjustment.
2. It is recommended to check the status of the shock absorber oil seal every 5000km.
3. After intense driving, you need to cool down for 30 minutes before adjusting.
4. In winter, 2-3 sections of damping should be appropriately reduced.
Through the above structured adjustment methods and the practical experience in hot discussions on the entire network, you can adjust the D2 shock absorber system more scientifically. Remember to use the #D2 suspension adjustment topic on social platforms to share your modification experience!
