Relax, holmes. Most of the questions you're asking can only be answered by the manufacturer. Just because someone "trolled" you doesn't mean you're actually getting trolled. If you said you know absolutely nothing about modding, aftermarket kits, and wanted to clarify the stuff you don't understand in regards to what the manufacturer told you, you probably would've gotten a better response.
Personally, I think the kit looks like ass, but that's what people say about the LFA kit and I think the LFA kit is hot shit.
