Realistically, the weight difference is negligible. Yes you have 3 gallons fewer fluid, and the trans itself is maybe 50lbs lighter, but you have to keep in mind you also have a much heavier flywheel and a clutch and pressure plate which together are notably heavier than just a torque converter. You could get a lightweight flywheel, but on a heavy car like ours, especially one driven on the street, this is going to make it a PITA to drive since you will have to rev the hell out of the engine and slip the clutch like crazy just to get moving from a stop. Plus all the weight of the trans is already towards the center of the car, so any effect on weight distribution is going to be so small it won't be noticable. Don't get me wrong, I am probably the biggest advocate of the T45 swap on this site, and you absolutely should do the conversion, but in terms of weight distribution or reduction, you aren't going to get very far from a T45 swap. On the other hand, it does help handling quite a bit because you can now hold the trans in a particular gear and use engine braking to shift the weight of the car slightly, which will help the car get through the corners.
