Choosing additional equipment for a modern Chinese car often becomes no less difficult a task than purchasing the vehicle itself. The market is overflowing with offers, and owners of crossovers and sedans from the Middle Kingdom are looking for ways to personalize their vehicles, making them more expressive or functional. One of the most popular and visually noticeable solutions in recent years has become top, which changes the silhouette of the car beyond recognition.
Installing such an element requires not only financial investments, but also a deep understanding of technical nuances. It is important to consider that the Chinese auto industry, represented by such giants as Geely, Chery or Haval, has its own characteristics of body geometry. An incorrectly selected design can disrupt aerodynamics or even cause damage to the roof during installation.
In this article we will look in detail at how to choose the ideal option for your case. We'll look at materials, fastening types, and legal considerations that are often overlooked. You will also learn how not to turn a stylish accessory into a source of constant problems with noise and vibration.
What is a top and why is it needed on a modern car?
A roof spoiler, or roof spoiler, is an aerodynamic element mounted on the top of the body. Initially, its main function was considered to improve downforce and stabilize the car at high speeds, which is critical for sports cars. However, in the mass market segment, including popular Chinese brands, this element more often plays a decorative role or serves as a base for securing cargo.
Crossover owners Lixiang or Voyah the top is often used as a platform for installing additional lighting or luggage systems. This allows you to transform a city car into an expedition car in a matter of minutes. In addition, a well-designed element can reduce aerodynamic drag, which theoretically improves fuel economy on the highway.
⚠️ Attention: Do not confuse a decorative plastic cap with a full-fledged aerodynamic element. Cheap analogues made of ABS plastic without an internal frame can come off at speeds over 120 km/h, creating an emergency situation on the road.
There are several key reasons why car enthusiasts decide to upgrade:
- 🚀 Improving the visual perception of the car’s profile and giving it a sporty character.
- 📦 Possibility of attaching additional equipment (bicycles, skis, expedition baskets).
- 🛡️ Protection of the rear window from contamination when driving on a wet road (relevant for certain shapes).
- 💡 Integration of additional brake lights or LED strips for increased visibility.
Types of structures and materials of manufacture
When choosing a top for a Chinese car, the material of manufacture is of paramount importance. The durability, weight and appearance of the product depend on it. Most manufacturers use three main types of materials, each with its own advantages and disadvantages. Understanding these differences will help you avoid overpaying for unnecessary features.
The most common material is ABS plastic. It is lightweight, cheap to produce and can be painted to match the body color. However, plastic is sensitive to ultraviolet light and can fade over time or become brittle in the cold. For urban conditions this is an acceptable option, but for harsh climates and high speeds its reliability is questionable.
The hidden benefits of carbon
Carbon fiber is not only 40-50% lighter than plastic, but also has a unique weaving structure that dampens microvibrations. This makes it an ideal material for those who value a quiet interior and maximum structural rigidity.
A more advanced option is considered fiberglass (FRP). It is stronger than plastic, holds its shape better and can withstand more severe loads. Fiberglass is often used to create complex geometric shapes that cannot be obtained by casting thermoplastic. The cost of such products is higher, but the resource is much greater.
The premium segment is ruled by carbon (carbon fiber). This is a choice for those who are not limited by budget and want to get maximum quality. Carbon tops are incredibly light and durable, but they require careful handling and special care. Scratches on carbon fiber are immediately noticeable, and restoring the varnish layer is an expensive process.
| Material | Weight | Strength | Price | Recommended Use |
|---|---|---|---|---|
| ABS plastic | Low | Average | Low | City, decor |
| Fiberglass | Medium | High | Average | Route, active recreation |
| Carbon | Very low | Very high | High | Sports, premium tuning |
| Aluminum | High | High | Average | Expedition equipment |
Compatible with Chinese brands: Geely, Chery, Haval
Chinese automakers have made huge strides in design in recent years, but their approach to standardizing body parts still differs from the European one. When looking for a top on a model Haval F7, Geely Monjaro or Chery Tiggo owners often face the problem of lack of factory mounting holes. This requires the use of universal solutions or custom fit.
Particular attention should be paid to the model Geely Coolray and its restyled version. Due to the aggressive roofline, many utility tops require significant modification or the use of special adapters. At the same time, for Haval Jolion the market offers many ready-made solutions, since this car is very popular among tuning studios.
It is important to consider the curvature of the roof. Chinese designers often use complex double bend radii, which are difficult to replicate in a factory environment without 3D scanning. Cheap, generic tops may only fit at the edges, creating gaps where moisture and dirt can get in, causing corrosion.
When purchasing, be sure to check with the seller for the compatibility list. The phrase “suitable for all Chinese crossovers” in 90% of cases means that the product will require serious work with a file and sealant. The ideal option is to look for an accessory marked with a specific VIN code or model.
Installation nuances: to drill or not?
The issue of body integrity when installing a top remains one of the most painful. There are two main installation methods: mechanical (with drilling) and chemical (using two-component tape or polyurethane glue). The choice of method depends on the design of the top and your plans for the future.
The mechanical method is considered the most reliable, especially for heavy structures or vehicles that are often operated at high speeds. In this case, holes are drilled in the roof through which the fastening bolts pass. Important: drilling sites must be carefully treated with anti-corrosion agent and closed with plugs, otherwise metal corrosion will be a matter of time.
⚠️ Attention: Before drilling into the roof, be sure to remove the headliner from inside the interior to control the drill's exit and not damage the electrical wiring or safety amplifiers that often run inside the pillars.
The chemical method (using 3M or similar adhesives) looks more attractive to those who are afraid of breaking the tightness of the body. Modern adhesives can withstand enormous loads, but they require a perfectly clean and grease-free surface. In addition, it will be extremely difficult to remove such a top without damaging the paintwork (paintwork).
☑️ Preparation for installation of the top
There is also a combined method, when the main points are fixed with glue, and additional points - mechanically. This allows you to distribute the load. For Chinese cars with thin roof metal (sometimes found in budget segments), mechanical fastening using wide washers and sealant is preferable.
Aerodynamics and impact on fuel consumption
Many drivers mistakenly believe that any protruding element on the roof increases fuel consumption. This is not always the case. Properly Designed aerodynamic top can even improve body aerodynamics by directing air flow and reducing turbulence in the trunk area.
However, if you install a high "crest" or a massive, irregularly shaped structure, the effect will be the opposite. The air flow will be disrupted, creating a vacuum zone that literally pulls the car backwards. For Chinese electric vehicles such as Zeekr or Nio, where every kilowatt-hour counts, this can become a critical factor.
Carry out a simple test: after installing the top on the highway at a speed of 100 km/h, listen to the noise. A whistle or hum indicates a violation of aerodynamics, which will inevitably lead to an increase in fuel consumption.
The effect on consumption can range from 0.5 to 2 liters per 100 km, depending on the shape of the product and the speed limit. At city speeds the difference is almost unnoticeable, but on the highway when overtaking it becomes noticeable. Therefore, for daily city driving, the shape of the top is of secondary importance, and for highway highways it is of paramount importance.
It is also worth mentioning sound insulation. Cheap tops can begin to vibrate at certain frequencies, creating an annoying hum in the cabin. High-quality products are equipped with special rubber dampers and have thoughtful edge geometry to “cut” the air and not make noise.
Legal aspects and registration of changes
In Russia and the CIS countries, the installation of additional elements on the body is regulated by the Technical Regulations of the Customs Union. According to the current rules, installing a top (spoiler) does not require making changes to the design of the vehicle (SBCTS), if this element is certified by the vehicle manufacturer for a given model or does not affect safety.
However, traffic police inspectors may ask questions if the top has an aggressive shape, blocks the view through the rear view mirror, or has built-in lighting equipment (strobe lights, flashing lights) not provided by the factory. In such cases, you may be required to dismantle the element or undergo a registration procedure.
Keep receipts and certificates of conformity for the purchased top. Having documents from the manufacturer indicating the car model often helps to avoid fines and problems when passing a technical inspection.
Separately, it is worth mentioning the lighting elements. If your top has additional lighting built in, it must comply with GOST in color and brightness. Installing xenon in the top or flashing lights is strictly prohibited and entails deprivation of rights. Standard LED brake light repeaters, as a rule, do not raise any questions.
If you're planning to sell your car, having unregistered changes could be a deal breaker for the new owner. Therefore, the “buy-set-forget” approach only works with the most factory-made and inconspicuous solutions. In other cases, it is better to play it safe and have a package of documents on hand.
Frequently asked questions (FAQ)
Do I need to paint the top before installation?
Most tops are sold in "primer" (gray or black). Yes, for an ideal appearance and to protect the material from fading, they must be painted in the body color. The exception is black matte tops for black cars or carbon products with a varnish coating.
Will my Chinese car be able to support the weight of the top at high speed?
Roofs of modern Chinese cars, such as Haval or Geely, are designed for certain loads. A decorative top weighing up to 3-5 kg will not have a critical impact on the design. Problems can only arise when installing heavy expeditionary structures without taking into account the attachment point.
How to care for your top in winter?
In winter, it is important to regularly clear the junction of the roof and the roof from snow and ice crust. Ice, when expanding, can damage the paintwork or unstick the joint if adhesive tape was used. It is also recommended to treat rubber seals with silicone grease.
Does the top affect the car's warranty?
Formally, the installation of non-standard equipment may be grounds for denial of the warranty on body elements (roof, pillars) if it is proven that the defect (for example, corrosion) arose precisely because of the installation of the top. This does not affect the engine or gearbox warranty.
Can I install the top myself?
You can install simple models using double-sided tape yourself, following the instructions. However, for mechanical fastening with drilling, it is strongly recommended to contact a specialized service so as not to compromise the tightness of the roof and not damage the paintwork.
