Does anyone know what sizes fit the 8th gen civic without modifications?

Id like to get a set of 18's and maybe lower it a inch but ive no clue what fits.

I want the car to run the same without rubbing or bottoming out over bumps.

thanks.

 

Stock are 17x7JJ, standard Si tires are 215/45, you have lots of space... 18s for sure on 40s and 19s (ulp) on 35s...all will have the same or very similar aspect ratios. Good luck, post some pics.

 

I run 17x8 and 17x9 +38 on 215/45's if that helps any. I think that is getting pretty close to the limit with ZERO fender mods needed. (need smaller tires up front though)

P.S. you can get bigger on there with a roll, I think 18's would fit pretty easy.
