Wanted some advice. I have a 08 535i and would like to use the PIAA wipers. I have 2 options:
1. Buy the complete wiper set from Amazon - PIAA 97351 Silencio X-TRM Black 26"/23"
2. Buy the inserts from Amazon - PIAA 94060 Silicone Wiper Blade Refill, 24"

First one is 70 bucks and the second is 20.

Question is can I fit the PIAA inserts into the stock 08 535i wiper blades and would it perform a well as the low profile set? (am worried about width here as 24" at 5/16 of an inch where as 22" is 1/4 inch as well as length). According to Amazon the original stock sets are both 24" Bosch 3397118955 Original Equipment Replacement Wiper Blade - 24"/24" but some folks have reported different lengths.

 

the original sizes for your BMW 535i 2008 should be 24" and 23". Pinch tab wipers
