I am wanting to lower my 4th Gen UKDM but not sure what springs to buy as I want to use the stock shocks. I have photoshopped the desired height I am wanting as I am not sure what kind of drop I'd need to achieve it. I don't want it too low so it scrapes everything but enough for a nice ride and looks good.
I've been looking at Eibach Springs kit that has the 30mm drop, not sure if that would be enough?
Pictures below:

Any help would be appreciated.
Cheers
