Hi
I have RRC seats in my 110, although i didn't fit them it doesn't look like it was an over complicated job. The two things i have noticed are, because they are pretty wide the sides come into contact with the doors and the cubby has been narrowed as well, the seats are super comfy and completely adjustable.
And just as a footnote i bought some HDC covers for them but ordered "new" shape instead, so if anyone has covers for "classic" seats and wants to swap let me know.
foozoo.
