A car's front splitter, also known as a front spoiler, is typically a flat or curved structure mounted on the bottom edge of the front bumper, extending forward and downward. It's made of a variety of materials, including visually striking carbon fiber and durable ABS plastic. From the outside, the front lip appears to add a delicate or aggressive "chin" to the vehicle's front end, extending close to the ground and enhancing the vehicle's visual impact.
A car rear spoiler is a wing-like structure mounted at the rear end of a vehicle's trunk lid or above the trailing edge of its roof. Its design is directly inspired by aircraft wings, but its function is the opposite: while aircraft wings generate lift, automotive rear wings are designed to generate downforce. Wings come in a variety of forms, from discreet, flat-fitting ducktail spoilers to massive, GT-style wings with complex, adjustable wing angles.
Both are key appearance kits that significantly enhance the vehicle's visual sportiness and personalization, and are iconic elements of modification culture.
The front splitter increases the downforce on the front axle, and the rear spoiler increases the downforce on the rear axle. The combined effect is to improve the vehicle's high-speed driving stability, tire grip and handling limits.
This is the most intuitive difference. The front splitter is installed at the bottom of the front end of the vehicle, while the rear spoiler is installed at the top of the rear end of the vehicle.
This is a practical function unique to the front splitter. Its low-position installation provides natural protection against minor road scrapes and provides support. A rear spoiler, located high up on the rear of the car, offers little in the way of physical protection.
The front splitter mainly enhances the front axle's grip and steering response, while the rear spolier mainly enhances the rear axle's stability and tracking.
Core Features | Front splitter | Rear spoiler |
Core role | ✅Generates front downforce, manages airflow at the front of the car, and reduces airflow entering the bottom of the car | ✅Generate rear downforce, optimize rear airflow separation, and reduce turbulent drag |
Key Impacts | ✅Improve front wheel grip, optimize steering response, and reduce understeer tendency | ✅Improve rear wheel grip, enhance high-speed stability, and suppress oversteer tendency |
Additional Features | ✅Protect the front bumper and lower parts from minor scratches | ✅No significant additional protection features |
Influence of visual center of gravity | ✅Lower the visual height of the front of the car to increase the front aggressiveness and ground-hugging feeling | ✅Improve the visual height of the rear of the car, increase the sense of power and sportiness of the rear |
Installation location | ✅Front bottom of the vehicle | ✅Top of rear end of vehicle |
Aerodynamics role | ✅The basis of vehicle aerodynamic management, controlling airflow inlet | ✅The key to vehicle aerodynamic balance is managing airflow outlets |
Step 1：Thoroughly clean the mounting contact surface at the bottom edge of the front bumper to remove any dirt or oil. Align the front splitter with the bottom of the bumper, which usually has a slot or pre-set location.
Step 2：Use the self-tapping screws provided with the front splitter. From the bottom or side of the front splitter, screw them upward through the front splitter mounting holes and into the front bumper plastic body. It's recommended to tighten them by hand a few turns to position them, then tighten them with a tool. Tighten them evenly and gradually, using a diagonal pattern.
Step 3：Check whether all fixing points are firm, whether the front splitter is flat without any skew or local warping. Check whether the ground clearance is reasonable.
Make sure the cleaning area is clean
Precise pre-positioning: Carefully place the front splitter into the predetermined position under the bumper.
Check whether all fixing points are firm, whether the front splitter is flat without any skew or local warping. Check whether the ground clearance is reasonable.
Step 1：Thoroughly clean the trunk lid mounting area. Place the spoiler precisely in its intended location and temporarily secure it with low-tack masking tape. Observe it from all angles to confirm it is centered, symmetrical, and spaced as expected.
Step 2：Carefully peel off all the outer protective film from the tape on the fin base. Immediately align the tape, starting from the center of the fin base, press firmly outwards, applying as much pressure as possible. Ensure the tape makes initial contact and adheres.
Step 3：Finally check whether it is firm and not loose.
When cleaning, ensure that there is absolutely no dust, oil, water stains or any residue.
Carefully place the rear spoiler in the intended position on the trunk lid.
Choose a clean, windless place or a shady place.
It is highly recommended to consider and purchase the front splitter and rear spoiler as a set of aerodynamic components. The reasons are:
1.Aerodynamic Balance：Adding a rear spolier alone increases rear downforce. Without a corresponding amount of front downforce to balance it, the vehicle can appear nose-light and tail-heavy at high speeds, potentially inducing understeer and compromising handling stability. The front and rear components must work together to achieve optimal downforce distribution and neutral steering characteristics.
2.Visual coordination：A set of front splitter and rear spoiler with unified design language and matching style can significantly enhance the overall design integrity and sense of luxury of the vehicle, avoiding the visual dissonance of "top-heavy" or style conflict.
3.Maximize performance benefits：The two complement each other in function, and only by working together can the effect of aerodynamic modification be maximized, bringing about a qualitative leap in high-speed stability and overall handling confidence.
4.Discounted prices：This is also the most important factor to consider as a wholesaler. At the same time, purchasing can bring discounts on product prices to a large extent.
The material determines durability, weight, and texture. Check that the edges are smooth and burr-free, and that the holes are precisely positioned. Poor-quality products can easily deform, crack, and become difficult to install.
The price range is huge. Considering the cost-effectiveness, we need to find a balance between materials, brands, fit and actual needs.
A reliable supplier should provide clear product information, including photos and videos of the actual product. Good pre-sales communication can help prevent you from buying the wrong model. More importantly, they should provide comprehensive after-sales service: Can you easily return or exchange the product if there are any quality issues? Is there technical support available to answer any installation questions？
Honest suppliers will truthfully inform you of the advantages and disadvantages of their products and will not exaggerate the effects.

A car's front splitter and rear spoiler, one in front and one in the back, together form key external components that enhance a vehicle's aerodynamic performance. The front splitter, anchored at the front of the car, suppresses lift, regulates airflow, and protects the body, paving the way for precise steering. The rear spoiler, anchored at the rear, generates downforce, stabilizes the vehicle's stance, and optimizes aerodynamics for effortless high-speed driving. While positioned differently and focusing on distinct functions, the two components share a common goal of enhancing stability, enhancing handling, and enhancing the exterior. Working together, they achieve a perfect balance of dynamic performance. From understanding their core principles and differences, to mastering professional installation techniques, to choosing a reputable supplier like AMP-Z, every step plays a crucial role in determining the ultimate performance and driving safety.
