I randomly saw this in a shop , the shop specializes in all thing PEV, I had some hydro brake fluid issues, they set me up quick and easy, check my ride height, air pressure, the other brake, everything. I saw these red floppy worms on the floor and hanging up on hooks. I had to ask, it was pricey with the purchase and installation. I went home to research the inserts. Most reviews was ok, to just not worth it. I found most people are lazy and don’t do any basic checks and maintenance. The reason why customers gave it a not worth it reviews. It’s amazing. Expensive but it saves your sanity.
