Hi there, those rims are cool but i would advice you not to spend money on them...
altough i like the porshe replicas, a 17´wheel is much too big, and as you might gain some stability at high speed cornering, you sure to notice the lack of power on lower RPM.
altough if the car is powerful enought you may win 3/4 km/h at top speed, if the final diameter (tyres+wheels) is bigger
not to mention the price of each tyre in those sizes ...
And another thing, 17´wheel must have at least 205/215 - 40
that might touch the inside of the chassi, when cornering, or if the suspension is a little worn it might touch the upper inside...
so if you still want 17´ers , i would at least borrow a wheel to see if it fits well and doesn´t touch the chassi, even rolling...
This is just an oppinion, you do u choice
keep rolling

ps: those rims are all 5 holes , civic are normally 4x100... that also might be a problem
