Why do we use Polyethylene Composite for Flow Designs Splitters?

Strong, impact resistant, doesn't corrode or chip, and has excellent abrasion resistance (say… from scraping on driveways and road all the time?)

Carbon Fibre is better isn’t it?

As strong and light as Carbon fibre is, it CRACKS on impact or when under load and/or stress. Clearcoat will eventually fade & cracks and become undesirable
