it's the front and rear under spoilers, and side spats. the front and rear seem like urethane, and the side spats are fibreglass (i am guessing here as i don't actually know, the front and rear are quite bendy, but the side spats are solid).
the kit is genuine veilside and from a reputable seller but there are some issues with fitment in some cases. 2 body shops have refused to fit it because it may require shaving, and they don't think that the time it will take to fit properly will make it worth their while (i'd have thought if i was paying what does it matter, they charge by the hour don't they?)
