I just ordered 20B and 24A from Amazon
So at 21 inch blade should fit. I can't find a 20 inch blade in the PIAA Si-Tech line so I was going to try a 21 inch.
Bosh fitment guide state 24" driver side and 20" passenger side.
When I looked how wipers are working I saw that driver side practically cleans up to the top edge of the windshield while passenger side leave a gap there. So I looked at longer option and found that 21" fits just right in in lowered position and cleanes additional 1/2" on the top. On other hand 24" on the driver side I believe is too big. There should of be 23", but nobody offers that side, this is why 24" is used, but it's absolutely max for driver side, anything larger and it will stick out in vertical position.
