Lowering recommendations A3
 

I have a stock 2016 A3 1.8T. I want to lower it a bit and need some recommendations. It currently has stock 17" wheels and I plan to upgrade to bigger wheels 18 or 19 inch. I want to lower it a little and need advice on what to prepare for and what to expect. I've looked at some lowering springs and sway bars from ECS tuning,
