To be honest I am not sure. I got told fibreglass, but its painted on top and underneath so its hard to tell. However I am thinking its fibreglass.
Its quite heavy, very solidly built. But yeh it came off a Yellow GTT, so who knows maybe its ended up here?
Either way its well built, nice and smooth on the surface.
Its not a Blits bonnet no, but it is very alike. Obviously it has the two extra vents at the back, and they also "bulge". Not too much, just a little bit. so it should give the bonnet abit more shape and character.
Im just abit worried that the front vents are abit too far back for the purposes of rain... and leaking into the engine bay
