I would like to know if I get a stock A4, does it need to be lowered for 18' rims? Also is there a difference between the sports package and the sport suspension? The sport package is too much $, so i'm would like to know if I should get the sport suspenion?

 

You're talking about a brand new a4 then? If you get sports suspension you could likely get away with 18's without lowering it further... but lowerng it would make it look nicer.

Ask the dealer what the sports pkg includes...
