I think it's very worth it to lower your car. Usually, it's good to install performance shocks with the lowering springs because the OEM shocks aren't tough enough. It is kind of expensive and might range from $600 to $1400 (depending on what kind of springs/shocks or coilovers you get). Installation is usually around $160-$200. The spring/shock setup is great for daily driving. It's not too rough and it handles superb (less body roll and better cornering). The car also feels more secure on the road. Coilovers on the other hand are more rough on the road and are more expensive. They're also height adjustable. Hope this helps.
