I just purchased a 2007 Civic LX 4-door. The car came with steel rims and covers and I would like to install SI rims on the car. The LX has rear drums and the SI has rear disk brakes. Will SI rims fit on a LX Honda, if so can you think of any issues I mar run into other than possibly the speedo being off a little? Below are the tire sizes for the LX and SI.

LX P205 55 R16

SI P215 45 R17
