the only genuine piece i have is evoiii bonnet (not pictured in my avatar).. and compared to the fibreglass bonnet, the genuine one is so much better... its tough, still light in weight, the mesh is tough as! , it has the undertrays under the air intake vent, and other two vents.., compared to the fibreglass ones which only have meshing that looks like chicken wire....
the rest of my kit is fibreglass - front bar, sideskirts, rear pods, wing... and i just plain dont like it and intend to change it with genuine parts bit by bit.. look with fibreglass, they may look good, but it flexes, and if your car bottoms out, even the slightest scrape can cause the start of cracking in it.... and i dunno , but i can notice a hell of a lot more stone chips?
also just the thought of the genuine kit bolting in , compared to fibreglass just being screwed in with self-tapper screws.. i dunno
im just talking from my experience, for all i know my one could be made dodgy compared to other fibreglass kits ?!
but its from one of the major bodykit providers mentioned in these posts, so i doubt its just mine, its probably fibreglass in general ?
bottom line... if your intending to keep this car for a long time, youll be a lot happier buying genuine...
