Many owners are faced with the problem of finding quality parts, since factory plastic often loses its appearance, and cheap analogues from China may not fit the geometry. Proper selection of components requires an understanding of the body features, manufacturing materials and installation technology. In this article we will look at all aspects of installing the body kit on Nissan Teana J31, from choosing a manufacturer to final painting, so you can avoid common mistakes.
Types of aerodynamic packages for the J31 sedan
The tuning market offers several categories of solutions for Nissan Teana, and the choice depends on what style you want to achieve. The simplest option is “standard” body kits, which repeat the factory lines, but add a slight aggressiveness. These kits include a front bumper with large air intakes, side skirts and a rear bumper with an integrated diffuser. This option is ideal for those who value restraint and do not want to attract unnecessary attention to the modified exterior.
At the other end of the spectrum are extreme style sets Body Kit, which may include flared arches, roof spoilers and a hood with functional cutouts. Such kits are often developed by well-known tuning studios and are much more expensive, but they guarantee an exclusive appearance. It is important to understand that an aggressive body kit requires careful adjustment, since the geometry of the body Nissan Teana J31 has its own characteristics that can complicate the installation of wide elements.
- 🚗 Standard kit (front bumper, side skirts, rear bumper) is the most popular choice for daily use.
- 🚙 Set complete (complete set with extended fenders and hood) - to create a unique sporty image.
- 🏎️ Aerodynamic body kits with active elements (spoilers with speed sensors) are rare for the J31, but a possible option.
Materials of manufacture: polyurethane or fiberglass?
When choosing a body kit for Nissan Teana It is critical to pay attention to the material from which the parts are made. Polyurethane (PUR) is considered the gold standard for the budget and mid-range segment. This material is highly elastic, which allows the parts to withstand impacts during parking without cracking, and easily return to their shape after deformation. For Russian roads with their unevenness and frequent bumps, polyurethane is the most practical solution.
Fiberglass (fiberglass) is a material that is often used in expensive kits or to create unique parts. It is lighter than polyurethane and allows for a finer, sharper edge, ideal for a sporty look. However, fiberglass is fragile: with a strong impact it can crack, and repairing such a part will require time and special skills. The choice between these materials depends on your priorities: practicality or aesthetics.
Casting quality - This is another aspect that you should pay attention to when purchasing. Cheap Chinese copies often have bulges, uneven seams and require significant work before installation. If you order parts from local manufacturers, be sure to check whether computer 3D modeling is used to fit the elements to the body.⚠️ Attention: Never install a fiberglass body kit without first checking its flexibility. In winter, fiberglass becomes very brittle, and even a slight blow from a stone can lead to the formation of a crack.
- 💧 Polyurethane: shock-resistant, easy to clean, but may fade over time.
- 🛡️ Fiberglass: allows you to create complex shapes, lighter in weight, but afraid of impacts.
- 🔧 ABS plastic: rarely used for body kits, more often for radiator grilles.
Technology of installation and fitting of parts
Installing body kit on Nissan Teana J31 is a process that requires care and precision. Even high-quality parts may not fit perfectly “butt-to-shoulder” due to natural deformations of the body or casting inaccuracies. The first step is always "dry" fitting, where you place the parts on the machine without applying glue or tightening bolts. This allows you to see the gaps and understand which areas require sanding or adjustment.
Many owners make the mistake of trying to immediately screw parts onto standard fasteners. It is often necessary to drill holes or use additional brackets for proper fixation. The front bumper, for example, requires careful work with the fender liners and radiator grille so as not to disrupt the engine cooling system. Incorrect installation can lead to the body kit starting to rattle at speed or falling off at the first pit.
- 🔨 Use high-quality tools: screwdrivers, drills, files to finalize fasteners.
- 🧼 Clean all surfaces before installation: dust and dirt reduce the adhesion of glue and sealant.
- 📏 Check the symmetry: the gaps between the bumper and the fender should be the same on both sides.
☑️ Check before installation
Features of painting and surface preparation
After installing the body kit, a stage begins that often determines the final result - painting. Even perfectly fitted parts will look cheap if the painting is done poorly. Standard primer may not adhere, causing the paint to peel after a few months.
For polyurethane and fiberglass, it is necessary to use special adhesive primers that create a strong bond between the material and the paint. Often several coats of primer are required with intermediate sanding to achieve a perfectly smooth surface. If you want the body kit on Nissan Teana looked like a factory part, the color had to be selected exactly to the shade, taking into account the fading of the old varnish on the car body.
Temperature plays an important role in painting. In the cold season, the paint may apply unevenly, and in the heat it may dry too quickly, causing defects. Professional painters use temperature and humidity controlled chambers to ensure perfect results.⚠️ Attention: Do not try to paint the body kit with regular aerosol paint from a can without first preparing the surface. The result will be uneven and the paint will quickly begin to peel off.
- 🎨 Use adhesive primer for plastic (Plastic Primer) before painting.
- 🌡️ Work in a room with a temperature of at least +20°C for quality drying.
- 🔍 Inspect the part from different angles of light to notice defects before applying varnish.
Secrets of painters
how to avoid shagreen: To eliminate the “orange peel” effect (shagreen), you need to choose the right paint viscosity and spray pressure. Using a “liquid varnish” and allowing the correct time between coats also helps.
Legal aspects and registration of changes
The question of the legality of installing a body kit on Nissan Teana J31 remains relevant for many drivers. According to the law, any changes to the design of a vehicle that affect safety or appearance must be registered. If you replace bumpers with parts not included by the manufacturer, this is considered a design change.
Ignoring this requirement may lead to problems when passing a technical inspection or stopping the car by traffic police officers. Fines for non-conforming design can be significant, and in the worst case, the car can be prohibited from being used until it is restored to its original condition. Therefore, before purchasing and installing a body kit, you should consult with lawyers or specialists in registering changes.
- 📜 Check whether the selected body kit is included in the register of certified parts.
- 🚓 Avoid radical changes that may impede visibility or traffic safety.
- ⚖️ Go through the procedure for making changes to the PTS if you plan to drive legally.
- Yes, it's stylish
- No, the standard view is better
- I don't know, I haven't decided yet
- Depends on the quality of the body kit

Common mistakes when tuning Teana J31
Many owners Nissan Teana make the same mistakes, trying to save money or not having enough experience. One of the most common problems is installing a body kit without taking into account ground clearance. Low bumpers often cling to road irregularities, which leads to damage to both the body kit itself and the car’s suspension.
Another mistake is neglecting the quality of painting. Saving on materials and painters' services often leads to the fact that after six months the body kit begins to fade, scratch or peel off. You should also avoid installing arches that are too wide, which may interfere with the normal operation of the suspension when turning the steering wheel.
⚠️ Attention: Installing a body kit with lowered suspension without simultaneously replacing shock absorbers and springs with sports ones can lead to the destruction of standard suspension elements due to overloads.
- 🚫 Don’t skimp on preparing the surface before painting.
- 🚫 Do not ignore clearance recommendations for the selected body kit.
- 🚫 Do not use cheap sealant to fix parts.
Before installing the body kit, be sure to check the condition of the standard body mounts. If they are corroded or damaged, they need to be replaced, otherwise the new bumper will not hold securely.
