You don't need a racecar or 400hp beast to benifit from rear disc. They are there for a reason. To help you stop faster. Yes they are more expensive, and wear out faster, and dont' do as much work as the fronts.JRB said:otherwise this is a waste of money. Rear discs in general are a waste of money. Drums last forever with very little problems. They are easy maitenence. Changing to discs...unless you actually have use for them (ie. racing or high - over 400 hp)...is wasting your money and going to cause more headaches then it's worth. For one thing rear discs don't last as long as drums. Also most of your stopping power comes from the front wheels. Discs are more costly to fix. All in all, rear drums are better for a daily driver.
