Essential height differences 2013/2015 model

hi guys,

I'm still searching for my future HS (and sold the good 'ol 996 in the meantime).
In August, I rented a 2015 version for a day and from that moment I'm HOOKED !

Unfortunately enough, the 2015 version is WAY out of my league as a dad of 3 kids, so I am aiming for a 2013.
Problem is that the 2013 LOW is hardly available over here, so I have to work out a way to lower a standard version.
As far as I understood, the 2013 LOW and 2015 standard have equal ride heights/specs.


Can anyone tell me where the differences are and how to compensate them (cheap-ish) ?
I would like to keep the seat standard, as it felt pretty comfy over a distance of 250kms (170 miles) during my test ride.

- lower front fork through the yokes by 2 cm ?
- rear shock? err...

Well, I rode the 2015 (as a rental) and that one was perfect, really.
I sat on a 2013 (standard height and seat) and I could only tip-toe on it.
Scary, and even without some side winds.
I'm about 1.69 m (what is that? 5"5 ?) and not shaped like Mike Tyson, so I want to plant my feet firmly. I have no experience with a 2013 with lower seat, but I doubt a lower seat will do the trick.
