I just swapped my 50 tooth center diff for a lightweight spool and 40tooth gear. Saved 46 grams. That's almost half of what it weighed before. Wanted to go back to the 16 tooth pinion but it won't reach so I put the 20 tooth back in. Gonna test it out with the GRT tires and see what that does to my top speed. I also have a 34 tooth spur gear and a 28 tooth pinion. Is that combo too much for my factory electronics?
