By "sand bagging" I didn't mean Tesla's cars weren't hitting their advertised numbers, I meant that the hardware the lower speced cars come with seems like it could be capable of more, the awd being I believe an example of this.
You're right about the improvement from the staggered wheels. I'd seen the headlines generated by DArick's video, but actually watching the whole thing, yeah not as impressive an improvement. Though the times he is getting from a stock car are kinda nuts.
I'd also seen a video where the Tech Forum guy did a similar mod on a RWD model 3 and saw no 0-60 improvement.
