For the modification of 645 models, it is particularly important to choose the appropriate spring. This article will combine the hot topics and hot content on the Internet in the past 10 days to provide you with a detailed analysis of the 645 modified spring options and provide structured data for reference.
1. Analysis of hot topics of 645 modified springs
Recently, discussions about 645 modified springs have mainly focused on the following aspects:
| topic | heat index | Main discussion points |
|---|---|---|
| Spring material selection | 85 | Steel vs Titanium vs Composite |
| Spring hardness grade | 78 | Applicable scenarios for soft, medium and hard gears |
| Brand recommendation | 92 | Comparison of Eibach, H&R, KW and other brands |
| Modification effect | 76 | Balance between lowering the ride height and handling |
2. Comparison of core parameters of 645 modified springs
The following is a comparison of the core parameters of several springs commonly used for modification of 645 models:
| brand | Model | Material | hardness grade | Lower height(mm) | price range |
|---|---|---|---|---|---|
| Eibach | Pro-Kit | high strength steel | in | 20-30 | ¥1500-¥2000 |
| H&R | Sport Springs | Chrome silicon steel | Hard | 30-40 | ¥1800-¥2200 |
| KW | Variante 3 | stainless steel | Adjustable | 15-50 | ¥3000-¥4000 |
| BC Racing | BR Series | alloy steel | Adjustable | 20-60 | ¥2500-¥3500 |
3. Selection suggestions for 645 modified springs
1.Daily driving needs:If you mainly drive on urban roads, it is recommended to choose medium-hardness springs such as Eibach Pro-Kit, which can achieve a good balance between comfort and control.
2.Sports performance needs:For car owners who pursue ultimate handling, the H&R Sport Springs or KW Variante 3 are better choices, as they offer stiffer support and a lower ride height.
3.Budget considerations:If you have a limited budget, you can consider the BC Racing BR series, which provides good performance and adjustability at a relatively affordable price.
4.Professional modification suggestions:No matter which spring you choose, it is recommended to modify it with the corresponding shock absorber to ensure that the overall suspension system works in harmony. At the same time, it is recommended to adjust the four-wheel alignment after modification.
4. Precautions for modifying the spring of 645
1. After modifying the spring, the ground clearance of the vehicle will be reduced, so pay attention to the passability.
2. Increased spring stiffness may lead to a decrease in ride comfort, especially when driving long distances.
3. After modification, it is recommended to conduct a period of "run-in" to allow the new spring to fully adapt to the vehicle weight and driving habits.
4. Check the spring condition regularly, especially after driving on bad road conditions, to ensure there is no deformation or damage.
5. Modifying the spring may affect the original manufacturer's warranty policy. It is recommended to consult the dealer in advance.
5. The latest modification trends
According to recent discussions on modification forums, 645 owners are increasingly inclined to choose an adjustable spring system, which can adjust the hardness according to different driving scenarios, taking into account daily use and track needs. In addition, the use of lightweight materials has also become a hot topic. Although titanium alloy springs are more expensive, they can significantly reduce the unsprung mass and improve the vehicle's dynamic response.
No matter which modification plan you choose, it is recommended to carry out the construction in a professional modification shop and do a good job of debugging after modification, so as to give full play to the performance advantages of spring modification and ensure driving safety at the same time.
