i put some 17s on my sedan and wasnt too sure how it would work out but it did perfectly almost in the end.
i had some momos i picked up dirt cheap so i put them on my old honda and thought they looked alright and then put them up against my ke70 and they sorta suited it
so went to mag and turbo and sussed out stud adaptor plates which cost me about $230 i think, before even asking anyone if the wheels would stick out the guards or doing any measurements myself, just went and bought em. thought they would definatly be too wide because the mags are 7.5'' wid instead of the more common 7'' PLUS the stud adaptors were 25mm wide and looked about a mile too thick.
got home whacked them on along with the 17s while the car was standard height and they stuck out the front guards about 5mm if u looked straight down on the guard, and the back were inside but when the car bottomed out with a full carload that night the lip on the back guard chewed up the sidewall on the tire. so got my guard lips professionally rolled and lowered the dx.. looked pretty cher but when i hit a bump the rim yes RIM not the tyre was hitting the rolled bit on the guard and chewing that up because of the 7.5'' wide rim and 205 width tyre was sort of stretched across rim and the lip on the rim stuck out(really easy to kerb my rims). so i got a mate with a laithe to take the width down to 19mm on the back and ended up with the wheel perfectly sitting in the guard with no rubbage at all
i think the rear wheel arches should be the same wagon or sedan
the wheels were 40 offset not sure 40 + or -. whatever offset will fit hondas.
stud and offset adaptors also makes your selection of mags alot wider...anything that will fit honda for me
heres a pic, i tried to choose one to show how the back guards are filled out
