whats better

Whats better polyurathan, fiberglass, carbon fiber, or polycarbon body kits?

I say carbon fiber. most expensive but the best performance wise. but more importantly is the aerodynamics of an AERO kit. most BODY kits that are sold here are not true AERO kits, they are just designed for how they look. but if you go to a company such as Spoon, Mugen, etc. then you will find some real Aero kits that actually help your car.

But if you dont care about weight or performance then jsut go with what looks good. polyurethane is flexible but usually doesnt look too good. fiberglass is used often but can crack easily.

carbon fiber is best but also the most expensive.
go w/ a fiberglass one if you are going for looks.
they are cheap and serve their purpose well
