The effect of front and rear wipers on airflow varies from vehicle to vehicle. Some people use RainX and remove their wipers completely, which is a bit risky and not advisable. Others, however, simply remove the blades and store them in their car. When rain threatens, you can easily throw the blades back on. If you're worried about airflow over the wipers, this is probably your best option.
Another hair-splitting option is to replace your blades with a lower profile style.
Some people remove only the passenger side wiper.
Some people keep their wipers installed but put a cover over the wipers resting position to ensure air flow does not hit the wipers when they are turned off.
A related modification is to use a switch to stop the wipers when they are in the verticle position as it will give lower aerodynamic resistance.
