If you read the text carefully, these kits use fiber glass as well!
For large area fiber glass, the outer finishing is going to be very difficult to get a good smooth area. I think the quality will not be too good.
Btw, if you like the Clio V6 look then get the real thing, putting on this massive kit would slow down a good 2.0 Clio, and you would lose the best of both models. (lack of 3.0L powerful & no super fast response of 2.0L light body)
