1990 CRX 13-inch rims\\\205/60R13

I have a stock CRX dx, with stock 13 inch steel rims. I would like to put some 205/60R13's on with some fat rims. What specifications should I be looking for. Rim width..... Offset.......?????

I think I have 13x5. Should I go for 13x6,6.5 or 7.

I'm going to end up messing with the suspension later to get better handling. For right now I just need somewhere to start.

Thanx

If youre keeping the 13'' rim, there wont be much selection as far as performance rims and tires. Also, with a 13'' rim, when taking hard corners, the big sidewall will compress, which can hurt handling.
