i have a 00 civic. i put 18's on it and the rear rubs when i hit a dip . i was wonder if anyone had this problem. i would like to know if the shocks i have in the front are different and if so are they the same size as the back. i would think they would be different, because the front holds alot more weight. and the size i hope are the same . if so i will get some for the front to put in the back.
