How low can you go?
 

Soooooo i have a 2012 m3 hatch sgt and its a daily driver and i really really wanna lower it about 2-3 inches but i dont wanna lose that awesome smoooooth ride. Any suggestions?

And since i have your attention

Where can i find nice tinted headlights and taillights?

Last but not least

What are your thoughts on straight piping and the sound? If you dont like the sound what would you suggest?

For tinted headlights, you can order it online from the website of Headlight Armor.
