The KW kit is nice for what you get and is comfortable enough with EDC for DD duty. I would highly suggest you include E36 bumpstops and the MRF shaved upper support guides.
I went this route instead of the expensive coilovers as I wanted to 1) retain some of the warranty I still have and 2) would rather not drop $3k on coilovers just yet. Once the EDC shocks give out, the its JRZ time
The ability to also adjust height and corner weight was a big factor in my decision as well.
