Rofl - I have a baby on the way - I originally bought 17s specifically so I could get the rocketeer offroad big brake kit, but it looks like the funding is limited.
As for ride height - thats a tad lower than stock and thats probably where its going to stay - lowering it further will not increase performance and I have a very steep ramp up into my garage that I would have trouble navigating with more of a drop.
