it wont make it dramatically slower.
some things to keep in mind:
they break, bend and crack easily.
they are bumpers are prolly taller than the stock ones, so you are more likely to scrape the ground if you lower your car
good kits are
expensive, and cheap kits are..... well.... cheap
h:
the cost isn't just the cost of the kit. it is also the cost of shipping the kit, paint [or paint and labor if its painted professionally], all materials and tools needed to mound the kit, etc, etc
it will be played out in a year or two, because other people will have the body kit
you will attract attention from the police. if you and a red corvette were speeding right next to eachother,
you would prolly be the one that gets pulled over.
the money could be better spent elsewhere
but thats just my opinion
