Sounds like the fellow forum members guided you in the right direction.
The largest difference I have notice is when I had my Voightland Coilovers installed with an alignment and Corner balance...HUGE difference. It's like I'm driving on rails, Plus my car is on 19x 8.5 F and 19x10 R. It's a handling machine!!!!!
I also did the following mods to my car:
1) De-snorkel (gives a nice intake sound)
2) exhaust (for sound)
