The outdrives don't affect much how quickly you can spin up the diff, but the metal gears inside do. The aluminium ones are nice but you need to use the plastic blades with them. If I was running in mod I wouldn't use those on the front diff (if you run one).
Either way, I think Tamiya cheaped out and took too much material off the ends to allow the pin to be inserted. They should have cut only a narrow channel for the pin rather than take off half the outdrive tail which weakened them unnecessarily. Maybe it doesn't make any difference in the big scheme of things, but I'm just sayin'.

That hpi motor maybe heavier the newer motors. Using a lighter motor then you are using know.may help . The new Trinity D4 is 6 grams lighter then the Killshot. Also what kind of surface and grip level. My EVO 6 handles great on our bumpy high grip 140'x70' fast flowing track . I like the EVO better then my 418 or 417v5.

Why would you lock out the spring preload? The whole reason to corner weight the car is to set the preload!
I set the car up where it's ready to run, set the ride height, and then weigh it. You can see where the light corner is. In the evo6, it's actually the LR that's heavy. Since I can't get weight out of the LR, I add some back to the RF (because the car is underweight as it is).

With scales.

So, my take on this is to corner-weight with no preload. Get the corners close to what you want. You can then detweak the corners with spring preloads as usual. I verify this second step with setup wheels, with accurately set droop, by lifting the ends of the car and verifying the wheels leave the ground at the same time.
Let me know if I'm crazy

I need to try these tips! My car is very out of balance L/R about 55%/45% or 150g difference. Going to try a few things to even it out

Having the l/r balance not be 50/50 is not, contrary to popular opinion, the worst thing ever. What you are trying to do is get the splits the same, not just the wedge.
I can get my car to weigh right by adding "around" a turn in the LR spring and taking out a round in the RF. But then the ride heights are off, and the RF is too low to pass tech on carpet. That's why I set ride height first, then scale it, and then recheck it. I do it with the car set up to roll out on the track.
If you remove the shocks, add fixed rods,and put the setup wheels on, it might be useful for other activities (like, mocking up a corvette subframe to be installed under a 53 studebaker to get the ride heights right and adjust how the body hangs - seen that one done), but it assumes that everything else is exactly right (chassis isn't tweaked, has no flex, nothing is threaded in crooked). And then your going to have to redo it all over again with the it tires and wheels.
I started corner weighing my car when I was running direct drives on foam. If you hit something and bent the car, the scales would tell you where (assuming you knew what it Scaled at before it got wrecked). You could put the car back the way you had it with complete confidence.
