Well, from what I understand about drifting, weight transfer (the noticable kind, from right to left "lateral") is only going to effect your vehicle under two conditions.
1. Your weight distribution is severly off (e.g. 70/30)
2. Your suspension is either undercompensating or overcompensating for the movement.
Number two usually only applies in actual exhibition displays but this game is so realistic that it will apply here too. You spend the money on a customizable suspension system, yet you might not fully understand what it's capable of.
If you are wondering about the effects of the weight transfer in general than just think about it like this, your car is can only have 100% of it's own weight at one time. So speaking in a literal sense, if you soften your suspension, decrease your stablilizers and soften your shock bound and rebound than you can drift well, but it will take more to accomplish that since your soft shocks will absorb the momentum of the turn. Resulting in a left-right weight transfer of 70-80% and in some cases greater. Adversly, if you stiffen the same attributes (above normal stiffness of course) than you will notice that your car (even the infamous 4WDs) will lose traction almost effortlessly. The only downfall is that, at least on the track, you are sacrificing that crucial control needed to balance your car on that knife edge that is known as stylistic drifting.
As far as drawing out your weight transfer graph and telemetry, you are asking people who have never seen your car and can only try to replicate it on their own systems to predict what it is going to do in a turn or drift. That is nearly impossible, not to try to bust your bubble, I know how frustrating it is, but, my suggestion is to run your car a few times with various suspension settings to see what how your car behaves and what it likes.
In essence
Weight transfer effects your car greatly in a turn, but that's only one thousanth of one percent of the variables in a successful drift.
I hope you could follow that, because I just broke it down to the short and sweet, in the Corps we have a saying
KISS
Keep It Simple Stupid
That's the simplest way I could think to describe it, if you still have questions, PM me or just ask on this thread and I'll get back with you ASAP. Or 15 minutes prior to that LOL,
Sorry a bit of Marine humor, it's a Devil Dog thing HAH!!! Just playing around.
Semper Fidelis and Good Luck To You,
