installing body kit

i am buying a body kit for my 94 civic and was wondering how hard it would be to put on and why people say professional insallation recomended. and my car is already lowered 1.5 in the front and 2 in, in the back and was wondering how much lower it would be or if i could make basic land clearance

aight, it depends, if it is fiberglass it would be pretty hard because MOST of them are not exact fit, Urethane is pretty good, n fact go with that

the one im buying says its garanteed to fit so i think im gonna buy it

even with urethane kits there are always fitment issues...the manufacturer is always going to say its got a perfect fit. but thats not always true. they say professional installation recommended becuase there are a lot more issues to deal with then just bolting up the kit. there is fitting, finishing, painting, pre-fitting again...lots of stuff. if you have no clue how to work with fiberglass or any body work whatsoever then just let a pro do it.
