From my exiperence. If you really want all that you say. The easy way is more cells. a 9xl on 14 cells verse on 18 cells is a difference. I can get longer run time faster speeds and more power. AS far as the buggy rears yes I do run them. I kept breaking up the stock diff one my set up. The buggy is 3.31 and the stock is 2.87. With the 16 51 gearing with buggy diffs it is geared almost the same as a stock emaxx. as far as heat on the 9xl. I had some heat problems on esc with 20 51 gearing but i had 18 cells on it as well. :D I like to go fast.
