I wouldn't touch that ebay crap for free. I've mounted/fitted more than a dozen sets of that stuff, and work with A LOT of shop owners who have worked with similar and more amounts.
The stuff is pure crap. In all fairness, the paint is actually impressive considering the price (not actually good, just considering how cheap it is, its better than I thought it would be), but the bodywork itself is really crappy. I know there are a few people here and there that will say they had a good set, but ask any professional and they usually can't say enough bad things about it.
The street bodywork doesn't line up well at all, panels have uneven edges, headlight holes are too wide/thin, OEM tabs break off because they are bonded after the molds. The plastic itself is a cheaper, more brittle ABS than OEM bodywork.
While I think this is a bad choice for street bodywork, I think it is a HORRIBLE choice for race bodywork. That stuff will shatter and crack all up the first time you go down...and thats it. Not really worth the effort it takes to repair plastic.
