>>I wouldn't recommend a torque converter for a daily driver. Launching at every single intersection and stop sign has to get old. Nevermind sitting in stop and go traffic, or inching into a tight parking space. Are those things rigged so that they have a lower stall speed for Reverse? <<

I never had it done but have read from other's who have that it's not really "launching" at every intersection. They say it's fine for daily driving. Supposedly instead of the car moving at a lower rpm it starts moving at a higher rpm so when you touch the gas in day to day driving it should be tolerable you just have to get used to it. Best analogy I can give on how it would probably be would be like pulling on a longer rubberband to build the same tension as a shorter one. You have to pull a little further back to get the same amt of tension. You can always customize the stall speed or the rpm when the tranny starts moving the car to suit your needs to get a decent balance of daily drivability and performance. I don't know about adjustment for reverse gear though.. I would think not.

lighter doesn't matter unless it's extreamly lighter than stock. If your rims are lighter but larger it'll take more power to make the wheels spin since the outside diameter of the wheel and tires are further out from the center. You'll go faster with 16's that are slightly heavier than your stocks than 19's that are slightly lighter. Weight of the tires also make a difference as well.
