The lower mesh area is stock. I'm just ocd when it comes to my car so it just looks glossy from being squeaky clean lol.
The ACS springs dropped the car approx 1" both front and back. Its a noticable change as you could see in one of my pics where the car wasn't dropped yet. Wheels didn't really change how low or high the car looks. I have on my stock msport wheels now for the winter and the car just looks like a sports package car should look like.
No issue with alignment at all. Honestly i didn't even get it done after the spring install because of all the concerns about how some people having issues with the car pulling to one side. My car didn't pull at all so didn't want to mess with it. Plus its only a 1" drop so its not that big a difference.
