Review on 🦈 Enhance Aero Performance with Alpha Racing 10pcs/Set Diffuser Shark Fin Kit and Spoiler Roof Wing Air Vortex Generator in Carbon Fiber Pattern by Chris Norman

High gloss cheap plastic. I have not used them as they are too high above the roof surface. The slats are very flat and cannot follow the natural curvature of the roof, causing the leading and trailing edges to already peel off. The glue used is too long and leaves a 2mm difference between the surface and the body of the fin, giving it a cheap look. The photos show the dimensions of what I received as there are reviews showing different specifications. Usage is completely flat and people won't look at them closely.
