First upgrade is gonna be the diff. Stock diff is geared and is a heavy 41.5 grams. I replaced it with an MIP super ball diff which weighs only 33.5 grams. Since I had my scale out I lost a few more grams with a Robinson Racing pinion, 2.4 grams vs. the stock pinion at 7.6. I also replaced about half the screws with titanium ones.

SPA 240WS is the power plant
