It seems to me the stock wiper blades on my '06 R52 are a bit too short. I'm not sure I have the correct blades on there, the rubber measures about 17.5" (left/driver) and 18.5" (right/passenger). It appears I could go another 2" on each blade to have better coverage without hitting the edges of the windshield.

Anyone do this? Do I have the correct size blades on there?

 

I use the PIAA 19" Blades on all of mine

 

18 driver / 19 passenger - that is what I run.

 

With the stock blades there’s a chunk at the top that doesn’t get touched and it’s annoying. Maybe it’s just me.
