Essential Mods for my '13 roadster

[KraTToR]

Hi every1, been skimming the forum for the last week ago and all I've to to say is *woW*.. There is a massive amount of info here.

So I'm starting to think about tuning my new manual Cherry Black sport/nav 'vert and was looking for feedback on my ideas and questions. Main thing is I'm not tracking the car and I want the car to be usable and not to loud or aggressive Just quality tweaks.. I'm a 50yr old guy so I dont want a commando spoiler or ground lighting etc...LMAO....

- Drop: Eibach pro kit w/camber kit (had this on my G-37 and liked the ride)
- Spacers: 15mm all around (pulled these off my G-37)
- Intake/Filter.... what are your thoughts on the K&N CAI? It seems to be a pretty decent price. Can I run this in the winter? I live in Ontario (how easy is it to switch back to stock if I need to?). Option 2 is K&N drop ins. I've used these b4 but didn't really see any advantage except that they can be re-used
-Exhaust: Looking for something that sounds close to stock until you open her up... I like the sound of the Fast Intensions and GTHAUS. GTH is prob. to loud tho.
-Wheels: I love the Vossen CV2's w/ the black background.....
Anything else I should consider?

Thanks in advance!

Cheers,
Patrick.
