4:10 Performance Gain
What should I expect going to 4:10 rear in a stock 08 that now goes 12.7 @ 115? I need to overcome the driver deficiencies the 08 is saddled with.

If you're not using sticky tires, which it doesnt looks like, the torque multiplication the gear change will provide it's just going to make matters worse. Get some good drag radials and learn how to max out the current combo, then think about the gear change.

Before you dive into gears you should try to get the car working as it sits. Unless you're at terrible high altitude that car is capable of much more bone stock. Realistically it should be in the low 12s trapping another 2mph or so. Adding gears to that is just. Going to make tbharder to launch. Get it working as it should first before adding gears

Gears make for snappier performance, but as others have said, it's going to make launching trickier. They will also require you to adjust your shifting. I'd concur with the recommendation to address tires and driving first, and look at suspension/alignment as well. Gears will do little good if those items aren't taken care of.
A side note-if you get the forced induction bug, you'll probably want to stick with stock gearing anyway.

When you get 4.10 gears RPM Trans will tighten up the diff lock. You will actually get better traction off the line with the gear set.
I know it seems crazy and although experienced people told me it would happen, I didn't really believe them until I found out for myself.
