Bilstein 5100 level question

Seriously thinking about leveling with the bilstein 5100s but will someone please tell me everything I actually need? I want to at least maintain my factory ride quality. Do I just need to buy the shocks or should I get coils and everything as well?

 

I'd think if you're trying to go minimal, you can do the 5100 and a 1 x 1/4" spacer. When retaining the stock spring you can raise the perch setting or whatever to adjust height.

Everyone will be slightly different. Might just have to bust out the tape measure and see what you need.
