the 9 MR setup is pretty good... zero lift kit, lip, add canards, VG, i dunno

 

i heard that c west slows down your speed but better cornering and braking

 

the apr widebody sounds pretty good. i don't know much about it, but the front does look like the oem fron tbumper, and on apr.com it does say "aerodynamic kit". just my 2 cents

mainly work on getting pieces that work together and are mad to go together. By this I mean get parts like the splitter/canards from the same maker, because what differs between two different makers of a product can be the difference form you getting more or less down force then you want. Consider all factors when your actually going for the performance side.
