Trying to decide between a spring lift or budget/spring spacer style. It seems the different between a BDS spring lift and a Budget/Spring Spacer type of lift is only a hundred or two more, if I am reading it right. Don't they take the same amount of time to install, since with both you are removing the springs? I'm kind of running out of reasons to go with the budget lift/spacer type of lift, especially if it's only a few hundred more.
