Hi, I'd like to lower my 2013 A4 Black Edition, would springs do the trick, or would I need new suspension, or coil overs? Total noob and have no idea! I'd like to drop an inch or more lower, and if possible get a bit of a less harsh ride from it; I don't mind it as it adds to the sportiness, but rear passengers don't like the ride so much, and I don't have drive select, so it's either stiff, or stiffer in sport mode. Ideally, something I could adjust simply, in the car or under bonnet, no jacking up malarkey Also, would I need to do anything else, such as tracking, adding spacers or anything? Thanks in advance, budget would probably be £300-£500, would that be enough for what I want?
