I love your car! Welcome from Iowa. All this talk about UMI lowering springs has me a little worried. I have two inch drop spindles on my car right now and they lowered it three inches. Little too low for my liking. I have a set of UMI two inch lowered springs and blazer spindles. I planned on changing too. I also have a six cylinder so that adds to my problem. I really don't want to do the job twice to get the ride height I want. Sorry I will not be much help to you. I am more of an engine guy than audio guy.
