Im looking to get the cwest front lip and rear valence along with the side skirts. Ive been searching and ive heard two diffenent things. the genuine c west is made of fg and some of the replicas are urethane which ive heard both is better and not. So whats what? Please help out. And i guess i might as well get some input is the genuine type-r spoiler really worth the $$ or should i get the replica? thanks guys and girls.
