ive got a 2010 activ sedan was looking @ some body add ons, was looking at something like the v-lip style add on/the centre lip style not to sure which one yet, i do like both

few questions: how much would this all cost?
where can i source such things?
I am not entirly car literate, so how easy/hard are they to install?
would professional help be easier? if so where can i find it:) lol??
thnx heaps in advance
