It depends. If there is not enough offset, you'll have trouble with the brakes fitting in. There are also some rims with very wide lips ("Deep Dish") that are intended for RWD cars that may not work. The offset is the distance (in mm) from the centerline of the rim to the mounting face on the rim. Positive offsets will bring the wheel further into the fenderwell, Negative will push them out. Anything in the 37-44 range should work no problem, but it also depends on how wide the new rim is. Remember that the offset of the new rim is relative to that rim, NOT the stock one. Assuming positive offsets (you shouldn't use negatives, the car will be bowlegged): If the new wheel has less offset (lower number), add the offset difference to 1/2 the difference in width between the 2 rims. If the new wheel has more offset, subtract the offset difference. Less than stock will push the rim further out, more than stock will pull it in.
Offset Calculator - It's a little cheesy, but it works... it's an excel spread sheet so just open it when it asks.
