Times change. The original reason for those "gaps" was to help cool hot brake drums and rotors on heavy muscle cars. EVs tend to use the brakes less, keeping them cooler, so it may make sense to sacrifice some cooling for some added range. Please don't attack people just for the sake of attacking. At least use a more neutral tone.
Ok, is will be neutral. I apologize for putting down these products. What I was referring to is that fads make pendulum-like changes over the years. As an old guy I have seen many fads come and go... and am tired of crazy new products which will only just put $$$ in the seller's pocket. Think of how cool computers went from big to small to big, and then to small again.
I just want to discourage others that may be susceptible to current hype because everyone today want to sell you something that is better, faster, cheaper, and most is really snake oil... SO..
If you want to buy these inserts because you are ok spending some bling $$$ to "customize" or "accessorize" your car, then go for it. People have always wanted to buy toys for their cars...
BUT, In my opinion, do not buy these things because you think is will do anything to improve performance or mileage range.
these inserts will never pay for themselves unless you already have a 3d printer and print them out essentially for free or a buddy does it for you. the gains are in the low single digit % realm, better for the 16" wheels as the holes are bigger there to fill, smaller for the 17" wheels as they are already fairly aerodynamic.
but most of us do these mods because we like to see the gains and we like to tinker, not because we are following fully financially backed decisions. I would not modify cars at all if i wanted to be financially responsible lol.
