Carbon Fiber Reinforced Plastics (CFRP) - Widely used in the performance automotive industry, a strong, light and very expensive composite material or fiber reinforced plastic. Similar to glass-reinforced plastic, which is sometimes simply called fiberglass, the composite material is commonly referred to by the name of its reinforcing fibers (carbon fiber). The plastic is most often epoxy, but other plastics, such as polyester, vinylester or nylon, are also sometimes used. Some composites contain both carbon fiber and fiberglass reinforcement. Less commonly, the term graphite-reinforced plastic is also used.

Coupe - a car body style with a close-coupled interior offering either two seats or 2+2 seating (space for two passengers up front and for two occasional passengers in the rear). For ordering purposes, Coupe refers to the 2-door versionl of a specific vehicle model (Example Honda Accord Coupe vs. Sedan)

Custom Installation - Refers to the installation of an aftermarket body kit which requires discretion on the part of the installer as to the techniques used to fit the body kit to the car prior to painting. Often times this includes use of 3M double sided adhesive, custom brackets to be built, sanding, prepping, painting, alterations, removal of part or all of the bumper support or any combination of these.

Fiberglass Reinforced Plastic (FRP) - A lightweight and inexpensive material used in the production or 98% of the body kits on the market. FRP is a composite material or fiber-reinforced plastic made of a plastic reinforced by fine fibers made of glass. Like graphite-reinforced plastic, the composite material is commonly referred to by the name of its reinforcing fibers (fiberglass). The plastic is most often polyester or vinylester, but other plastics, like epoxy (GRE), are also sometimes used. The glass is mostly in the form of chopped strand mat (CSM), but woven fabrics are also used.

Ground Effects Kit - a type of body kit that uses add-on peices that bolt to the existing OEM bumpers and rocker panels rather than a "Full" body kit that is designed to replaced the stock bumpers covers. Also referred to as a "Lip Kit" or as a "Lip" for individiual peices.

Hatchback - A hatchback car is an automobile design, consisting of a passenger cabin which includes an integrated cargo space, accessed from behind by a "hatch" tailgate or flip-up window. Most hatchbacks are distinguished from station wagons by not having separate side windows over the load area. Hatchbacks are also often described as three-door (two entry doors and the hatch) or five-door (four entry doors and the hatch) cars.

HID Kit - an innovative new style of lighting that exponentially increases the vehicles lighting capabilities over halogen lighting. HID lamps produce light by striking an electrical arc across tungsten electrodes housed inside a specially designed inner fused quartz or fused alumina tube. This tube is filled with both gas and metals. The gas aids in the starting of the lamps. Then, the metals produce the light once they are heated to a point of evaporation, forming a plasma.

Lip/Lip Kit - See Ground Effects Kit

Mesh - A honycomb shaped sheet of steel wire, often used to fill ports in body kits, hoods and ground effects to keep airflow while preventing larger objects from entering.

Polyurethane - A polyurethane is any polymer consisting of a chain of organic units joined by urethane links. It is widely used in flexible and rigid foams, durable elastomers and high performance adhesives and sealants, fibers, seals, gaskets, condoms, carpet underlay, and hard plastic parts. Polyurethane products are often called "urethanes". Polyurethane body kits and ground effects exhibit similar properties to the OEM materials used on most cars.

Rear Apron - the rear portion of a ground effects kit that bolts to the OEM bumper to add to its aerodynamics and styling. Also referred to as a "Rear Lip" or "Rear Under Spoiler"'

Reverse Induction Port - a vent found on several styles of aftermarket carbon fiber hoods that use a rear facing vent. Most reverse induction ports lip up in the front to keep air flowing over the hood without creating drag, or creating an eddie that loops cool air back into the engine bay.

Sedan - A sedan seats four or more and has a fixed roof that is full-height up to the rear window. Most commonly it is a four-door; two-door is rarer but they do occur (more so historically). In the U.S., this term has been used to denote a car with fixed window frames, as opposed to the hardtop style where the sash, if any, winds down with the glass. As hardtops have become rarer, this distinction is no longer so important. For ordering purposes, Sedan refers to the 4-door version of a specific vehicle model (Example: Honda Accord Sedan Vs. Coupe).

Spoiler - A spoiler is an aerodynamic device attached to an automobile whose intended design function is to 'spoil' unfavorable air movement across a body of a car in motion. This can result in improved vehicle stability by decreasing lift or decreasing drag that may cause unpredictable handling in a car at speed. Spoilers are often fitted to race and high-performance sports cars, although they have become common on passenger vehicles, as well.

Under Spoiler - an front or rear bumper attachment that adds to the aerodynamics and styling of the stock OEM bumpers, found in a ground effects kit. Also called a "Lip" or "Apron"

Widebody Kit- A body kit that consists of a standard 4 peice body kit plus fender flares, overlays or replacement fender/quarterpanels. Widebody kits give the vehicle a wider appearance and allow aerodynamic benefits for cars using wider wheels. Most widebody kits require extensive body work or shop time to install and are generally recommended for race only purposes.

Wing - Automotive wings are devices whose intended design is to generate downforce as air passes around them. Often used interchangabley with "Spoilers", wings do not simply disrupt existing airflow patterns but to add stability to the car by increasing traction.

Year - For ordering purposes, this denotes the production year of the vehicle make and model. This is often required to determine the correct part required for your specific vehicle.
