modifications > Rear Wiper Delete

Why did you delete the rear wiper on your RS?

The Focus RS is a hatchback, and that design is very prone to collecting dust at the rear of the vehicle. The downforce that Ford Performance provided with the rear wing only adds to that problem. Take a quick drive down a dusty road, then stop and take a look at your back window. It will be filthy! I had my detailer put a nanocoating on my back glass that helps bead up water when driving through rain. I only drive my RS in beautiful weather on weekends, so this shouldn't be a problem. If this was my daily driver the wiper would not have been deleted.

Also, the Focus RS is quite heavy for what it is. Every little bit of weight reduction helps unless you choose to add power/torque instead. I plan to keep doing both. :)

Weight reduction aids in performance. In drag racing for every 100 lbs removed your ET drops by 0.1 seconds. I will continue to race my RS more at local autocrosses and a few road course tracks, and removing this weight will help in quicker acceleration, shorter braking distance, and easier rotation for cornering.
