The difference from switching from 16 inch steel to 18 inch alloys is negligible if you do it correctly. In most cases you are increasing the rim size and decreasing the sidewall height of the tire in proportion. It is called plus sizing. I have used a few sites to see what works safely. You can try this one site that also tells you what the factory wheel and tire sizes are. It gives you loads of comparison info on clearance for suspension and brakes and speedometer changes. The only change you need to make is to purchase different lug nuts. The Steel 16 inch stock wheels use a cone shaped base seat and all the alloys use a radius seat so you cannot use them. i picked up a set from a local Honda dealer but you can find them at autozone.

When the speedometer reads 60 km/h actual speed will be 62.7 km/h
When the speedometer reads 37.28 m/h actual speed will be 38.96 m/h = 1.68 m/h difference in my case
No additional load on the drivetrain because you are adjusting the tires down in height as you increase the wheel height. Also the same vehicle with the same engine and drivetrain is available with 16, 17 or 18 inch wheels depending on which model you buy... LX, EX or Touring so it does not matter.
The end result is a wheel and tire combo that fits the wheel well nicely on the LX model.
Below are the details of the like new - slightly used set I purchased off ebay. They chage the whole look of the car.
