You should be able to simulate the stance of an S4 if you also use its shorter strut bodies. It's a very inexpensive way to drop your car somewhat. It's not going to have the slammed look or anything, but it's definitely an improvement over OEM A4 suspension setups.

 

i'm not looking into lowering my car a significant amount anytime soon. i just want a better ride and driving capabilities. IMO my car looks pretty good the way it is now besides the huge front end wheel gap. farther lowering options will have to wait until after college or unless i can get a set of koni streets for like 600 bux hehe.
