Polisport's side panels are produced with Polisport's exclusive technology - DGP (durable gloss polypropylene) - for this reason our parts are more durable and have a perfect combination of resistance and flexibility. On top of that, the Polisport replica plastics have a glossy finish and colors that perfectly match the stock parts. These parts also include a heat protection film and the washers and rubber grommets, just like the OEM parts.
