personally, IF i went with a fiberglass kit/ground effects, i would not buy cheap copies. from experience, i've seen copy kits that dont fit well or even fit at all. it may need major modifications to make it even look decent.

my friend worked at a body shop some of you may know (andy's autosport). they made the whole "combat z super street fighter bullshiit" kits. none of their own kits fit well on any car. i've even seen them drill into the frame to make a front bumper fit. :eh:

i would do it right the first time with fiberglass. it will save you most of the hassle that you'll have in the future.
