APR Performance Product Categories
Adjustable Wings
Wing can be considered as one of the most important aerodynamic device for any kind of racing. The amount of down force a wing can generate by itself is immense. That's why you see large wings installed on cars that participate in any kind of racing, where wings are not prohibited by regulations. APR produces both Carbon Fiber and aluminum wings. Carbon Fiber is a strong material which is light weight, and very durable, therefore is a great choice for performance aero products, but Aluminum on the contrary, is more ductile and less expensive. All Adjustable Wings are universal. Wing types include the GTC Series, Evolution GT Series, GT Series, Racing Spec GT Series, and also the Drag Series. The adjustability allows users to modify the angle of attack of the airfoils. First, this allows the user to optimize the angle of wing on different cars. Second, this allows the user to adjust the amount of down force needed, the adjustments of the down force can be used to alter the handling characteristics of the car for better driving results. Most OEM wings and spoilers are made for looks, but all Adjustable Wings are track tested and proven to change the handling of your car by aerodynamic enhancement . Please note that since most wings are installed in the back of the car, the increase in rear traction will cause the car to under steer more. To combat this issue, be sure to install other front aero devices, such as APR canards or APR wind splitters.
Aerodynamic Kits
Aerodynamic kits are often called body kits, but unlike most body kits that do nothing for your car's performance, A.P.R Performance body kits are designed and tested with performance in mind like all the other products. Unlike other body kits that can only generate down force, A.P.R Performance body kits can increase down force as well as reduce drag, and in most cases reduce the overall weight of your vehicle. The wider body of APR Performance body kits allows for the use of wider wheels and tires, which increased stance, allows higher cornering speed and stability, and also makes the car look more appealing in appearance. Each body kit includes a wide body front bumper, splitter/under tray, wide body front fenders, wide body side skirts, wide body rear fenders, wide body gas cap, and wide body rear bumper. A.P.R Performance body kits are made out of FRP, or Fiber Reinforced Plastics, the use of FRP makes it light weight and durable. A.P.R Performance state of the art manufacturing ensures that all the pieces will fit your vehicle like OEM parts. A.P.R Performance body kit is the best way to increase down force, decrease drag, widen the existing body, while at the same time give your car that high performance look. A.P.R Performance currently produces body kits for Ford Mustang, Honda S2000, Infinity G35, Subaru WRX, Mitsubishi Lancer Evolution, Toyota MR-2 Spyder, and Toyota Celica.
Flex Control Bars
APR Performance Flex Control Bar, or more commonly known as strut tower bar, was design to strengthen the front strut towers. Under higher speed cornering your car's chassis will flex to some degree. One of the most problematic areas is the front strut towers, when the front strut tower is flexing under high cornering load, the geometry of the suspension changes, and the twisting of the chassis will also decrease cornering performance. This problem becomes more apparent when a stiffer suspension or high grip tires are used. The Flex Control Bar reduces the flexing of the strut tower and reduces the twisting of the chassis by keeping them in a fixed position. Driver will notice a more precise turn in and higher cornering grip. Unlike many cheap strut bars on the market that are poorly designed and made, all Flex Control Bars have no welds and no pivoting points, thus eliminating weak points and flex points, thus maximizing the performance of a strut bar. All Flex Control Bars are made of 6061 billet aluminum; CNC machined, and have anodized coating, allowing for light weight and high durability, which ensures top performance of the product for a long period of time. Applications include Acura RSX, Honda Accord, Hyundai Tiburon, Mitsubishi Lancer Evolution, Nissan Altima, Subaru Impreza WRX, and Toyota Celica.
Formula GT3 Mirrors
One of the areas that generates huge amount of drag on a car body is the side view mirrors, because of their location and shapes. The most effective way to fix this problem is by using the Formula GT3 Mirrors. All Formula GT3 Mirrors are designed with a low drag aerodynamic shape in mind, other features include carbon fiber construction for weight reduction, wide angle length to eliminate blind spots, and wide range of adjustments. APR Performance Formula GT3 Mirrors increase your car's performance by decreasing drag and weight. Applications include Acura Integra, Honda Civic, Honda S2000, Lexus IS300, Mazda RX-7, Mitsubishi Lancer Evolution, Subaru Impreza, Toyota Celica, Toyota MR-2 Spyder, and Toyota Supra. APR Performance also makes a Universal version that can fit any car with minimum or no modifications.
Front Air Dams
A front air dam is a device that extends below the front bumper, commonly called front lip. Front air dam was first used in racing for reducing lift and increasing down force at the front of a race car. By reducing the amount of air traveling under the car and increasing the air travel above the car, the static pressure under the car will decrease thus reducing lift and increasing down force. While most people believe all front lips on the market are only for cosmetic purposes, both experimental and computational data showed that a properly designed front air dam will have a large effect on the reduction of lift, with minimum increase in drag. All Front Air Dams are made of FRP for light weight and durability, they are easy to install by using the existing factory mounting location and provide OEM fitment. Applications include BMW 335 Coupe, Chevrolet Corvette C6, Dodge Viper, Ford Mustang, Honda S2000, Hyundai Genesis Coupe, Infiniti G35 Coupe, Lexus SC 430, Mitsubishi Lancer Evolution, and Subaru Impreza WRX.
Front Bumper Canards
Canards are also known as dive planes or dive plates. A canard is also a very commonly used aero device for race cars. There are two important changes created by the use of canards. First, the downward inclined positioned canard will direct the leading edge into the oncoming air flow, which makes the "pushing" force being seen by the canards become a downward force, thus generating downforce. Second, the vortexes created by the canards will travel along both sides of the car, when properly setup, these vortexes will help the air flow under the car as well as toward the rear of the car, further increasing down force. All of the Front Bumper Canards are designed to generate maximum downforce. Carbon fiber construction and aluminum edging ensure light weight and durability. Applications include Dodge SRT4, Dodge Viper, Honda S2000, Lotus Exige, Lotus Elise, Mitsubishi Lancer Evolution, Scion tC, and Subaru Impreza WRX. A universal version that can fit any car with minimum modification.
Vortex Generators
To understand air flowing under a surface, we can model it as water flowing over a surface. When the surface is smooth and relatively straight, the air flow is said to be laminar, therefore the air is attached to the surface and flows over it very smoothly. When the surface is very rough or if there is a sudden change in the shape or angle of the surface, the air flow is said to be turbulent, that is when the air separates from the surface and the air flow becomes very chaotic and uncontrollable. In terms of car's performance, a laminar flow will be very smooth and attached, so all the aero device can do their job effectively. A turbulent flow will create drag and separation, preventing other aero devices from doing their job. A production car's surface will have many shape and angle changes; one of the biggest problems is the steep drop off angle between the roof and the rear window. This steep angle causes the air flow to separate and become turbulent, causing drag and reducing the effectiveness of the rear wing. Vortex Generators generate vortexes in the air flow and help direct it towards the rear wing. These vortexes energize the air flow, causing less air flow separation and turbulence. This decreases drag and increases the rear drag effectiveness. Applications include Mitsubishi Lancer Evolution X, GSR, MR, and GSR with SSS Package.
Front Wind Splitters
A front wind splitter is a device that extends forward at the bottom of the front bumper. Front wind splitter is usually just a flat surface protruding the contour of the front bumper. Just like an air dam, splitter was first used and tested on race cars for anti-lift and downforce generation. A splitter allows a high pressure build up on the top surface while at the same time creates a low static pressure region behind the front bumper. This pressure differential allows for down force generation and thus cornering stability. Because of the amount of force applied on the front wind splitter during high speed driving, a good splitter has to be very strong and properly supported. All Front Wind Splitters are reinforced by carbon fiber to ensure strength, lightweight, and durability. Every Front Wind Splitter comes with stainless steel support rods so the splitter can be securely mounted to the bumper. All of the Front Wind Splitters extend way beyond front bumper so they act as a fully functional under tray, which decreases drag at the front end of the car. Applications include Dodge Neon SRT4, Honda S2000, Hyundai Tiburon, Mitsubishi Lancer, Mitsubishi Lancer Evolution, Nissan 350Z, Scion tC, and Subaru Impreza WRX. Universal versions are available that can fit any car with minimum or no modifications.
Radiator Cooling Plates
Just like many heat exchangers, your car's radiator relies on air flow to cool down the coolant. More air flow means lower coolant temperature, allowing for higher engine performance. To increase air flow, one can use a front bumper with a larger front opening like the ones found in the Performance Aerodynamic Kits. Another way to increase the airflow is to block off all the areas where air flow can escape. One of those areas is the space between the radiator and the bonnet. Performance Radiator Cooling Plates blocks off these passages which leak air above the radiator, allowing all the air flow to flow through the radiator, increasing its effectiveness, lowering coolant temperature, and increasing engine performance. All of the Performance Radiator Cooling Plates are made out of carbon fiber for lightweight and durability. Fade resistant epoxy coating ensures all of the Performance Radiator Cooling Plates are able to stand up to the engine bay heat. Applications include Chevrolet Corvette, Ford Mustang, Honda S2000, Mitsubishi Lancer Evolution, Nissan 350Z, Subaru Impreza WRX, and Toyota Supra.
Rear Deck Spoilers
A spoiler is a device that changes the contour of the car in order to spoil the air flow movement, to generate downforce or reduce lift. A spoiler can be used together with other aero devices such as wings, air dams, splitters, and diffusers. Rear Deck Spoilers attach to the rear deck of your car and redirect the air flow that would otherwise cause lift at the back of the car. Much time has been invested into the design and manufacturing of their rear deck spoilers to ensure they look fantastic and fit just like factory oem spoilers. All Rear Deck Spoilers are constructed of dry carbon fiber manufacturing process to keep the weight at a minimum while at the same time increase the strength and rigidity. UV resistant coating ensures the spoiler will look and perform like new after years of usage. Application includes Chevrolet Corvette.
Rear Diffusers
A diffuser is a device that increases the air flow volume or speed. One of the most common uses of a diffuser on a car is under the rear bumper. A diffuser installed under the rear bumper allows the airflow under the car to smoothly transition into the air flow around the back of the car, this allows the air flow under the car to escape faster and smoother. You get an increase in velocity and decrease of the static pressure under the car, which again generates downforce. A diffuser can also be used in conjunction with other aero devices, often a rear diffuser will also increase the effectiveness of the rear wing or spoiler, by further increasing downforce and reducing lift. All APR Performance Rear Diffusers are either vacuum formed carbon fiber or FRP constructed for weight saving and durability. State of the art design and manufacturing process make sure that all APR Performance Rear Diffusers fit like OEM pieces and are easy to install. Applications include Ford Mustang, Honda S2000, Mitsubishi Lancer Evolution, and Subaru Impreza WRX.
Side Rocker Extensions
Side rocker extension, commonly known as side skirts, are an aero device that extends the rocker of a car. To minimize lift and reduce drag, we want to minimize the air flow under the car. Air can get into the underside of the car from both the front and the sides. Side rocker extension minimizes the amount of air entering from the side of the car, thus reducing both lift and drag. All of the Performance Side Rocker Extensions are made out of carbon fiber for lightweight and durability. State of the art design and manufacturing process makes sure that all the Side Rocker Extensions fit like OEM pieces and are easy to install. Applications include Chevrolet Corvette, Dodge Viper, Ford Mustang, Hyundai Genesis Coupe, Lotus Elise, and Lotus Exige.
