havin worked on many bodykits brought into the bodyshop were i used to work.. this is my opinion
firstly its cheap, so will be made of fiberglass, which means 90% of the time it wil be slightly mis shaped wont be totally flat, no mounting brackets ( which is why on many older cars you see screws used as bvody fixtures.
to make it look right it will need blasting with a DA on 80 grit to flatten out all the imperfections.... there will be many, and to try n flaten it out a bit. then obviously it will need 2pac priming ( high fill primer ) then will need flatting and prepping for paint. so all in all will be quite expensive and still wont be perfect.
if you want a body kit then i suggest using oem parts as then it will look like a proper sport instead of some fiberglass rep etc. will work out cheaper and look alot better.
or as said maby get some coilovers rokkor do them for 140 posted, then get some alloys, exhaust or something alot those lines
