How many suspension setups have you been through?

I'm new to BMW but not new to modding and I'm a few months in to my E92. Like most folks on here I'm not happy with my wheel gap. I've got a set of EPK laying around but after much research I'm thinking I don't want to spend the time and effort installing them and be disappointed.



How many iterations of suspension setups have you been through and what did you eventually end up with?
