The only problem with it is that it makes our 67 SS 396 Chevelle feel real slow

I know it is not a mini van but I like to push her buttons.
I will be ordering the front 2" lowering springs for it in the next week or so and the rear is bagged with ride height sensors so all you need to do is re-adjust the setting for up to a 3" drop
