Below we explain the different materials used in aerodynamics manufacturing.

1) Fiberglass
Pros: Fiberglass is a low cost manufacturing process that is excellent for low production runs. Fiberglass parts are also light weight and repairable when damaged.

Cons: Fiberglass will crack or shatter in an impact collision. Fiberglass parts may also need additional prep work for perfect fitment.

2) Urethane
Pros: The most durable and flexible material used in aerodynamics manufacturing. Fitment is usually pretty close to OEM.

Cons: Urethane parts are ultra expensive to manufacure and typically only used for high production runs. Urethane is also extremely heavy compared to other aerodynamics materials.

3) ABS Plastics
Pros: A great material for front lips and add on parts. Reasonably priced on high volume selling applications.

Cons: Becomes more prone to shattering and cracking in an impact in freezing cold temperatures.

4) Carbon Fiber
Pros: Carbon fiber is a very high tech material popular in both automotive and aerospace applications. In the automotive industry carbon fiber is often used for it's light weight, high strength, and unique 3d appearance.

Cons: Limited supply as the global market is currently using more material than can be produced. Carbon fiber is now becoming increasingly expensive every month due to the material shortages.

5) FRP Composite (Duraflex, VFiber, BMagic, AIT Racing)
Pros: FRP Composite products offer the near flexibility and durability of urethane components at a fraction of the cost due to lower production costs. FRP composite products are also extremely lightweight and repairable if you do damage the part whereas urethane products usually would have to be replaced.

Cons: Installation will still require similar procedure as traditional fiberglass kits with some amount of fitting required.
