With the optional blocks, you're changing a balance of inboard vs. outboard toe in at the rear. (Still set the overall rear toe to be the same: usually around 3 degrees total)
With all of your toe inboard, the rear end will feel more planted under acceleration, than if you're running some of the toe outboard.
On my TC5, I sometimes used the 1 degree blocks to get the car to rotate more on power. It's also useful on tracks with long corners, since it allows you to apply throttle sooner.
With the TC6 on carpet, I haven't had the need for that adjustment yet.
