when drag racing the wind passes through those holes so there isnt drag becuase when you have the stock bumper the wind causes a lot of drag sitting in the rear bumper so when u have cutouts or that aluminum piece the wind passes right through wich gives him better quarter mile times.....nothing outrageous just a few tenths but every tenth counts.

I swear, reading comprehension is becoming a lost art form or something.

alright for some this is hard to understand.......read slowly.

the rear bumper cover on many vehicles can essentially act as a parachute given the car is traveling at a high enough rate of speed. The purpose of the diffuser is simple to let the air pass through limiting such an effect. understand?
