Rex replacement
Hello, I wanted to know if it would be possible to replace the built in range extender with something else, perhaps something more efficient.
Re: Rex replacement
Yes, Wokeby makes an i3 trunk Extension, it's about 300 pounds lighter and therefore more efficient. 
But since you're talking about a replacement REX, I haven't heard of it being done – definitely no mention of aftermarket replacements. I've only seen a couple of owners reporting they removed the REX (due to a mechanical issue they didn't want to pay to repair).
