Wider Wheels To Match Flares

I have the Black widow II flares and I want to get wider rims.
THe fron flares are about 1-1.5 inches wide and the rears are 2 inches.
Regular sizes for civic are 7 inches wide right?
I want 8 inches wide, maybe 7.5 inches.
Or can i get the rears to have wider rims like 8-8.5 and the fronts to have 7.5-8.
Will it rub? probably....
How can I make it not rub?
Will handling be affected if I go with the fronts be smaller than the back?
Will handling be affected if I get wider rims?
Do these rims need to be custom made?

i don't think regualr honda rims come with 7 in wide rims, i think they come in 6-6.5 in wide. i have 6x8in rims on my car. i suggest you don't get it that wide because you will get torque steer and cornering is going to be bitch. of course there are other reason but these two factors will affect you the most. the best rims size for civic is 16x6.5in

My brother had 215/40/16's on his civic and they stuck out a little but. If i were you i would get 235 series or so if you want them out more.

hey, do you have any pictures of you flares??????
