I don't drift a lot, but sometimes I wish the rev-limiter was higher because I want to stretch a gear between two corners. Going 300 rpm beyond the ideal shift point is more senseful than shifting twice or adjusting the gear-ratios in some situations.
However, I don't think the limiter should be raised on all cars because the setting of the rev-limiter on real cars depends a lot on the specific car. On some it's 700 rpm beyond the red line, on some it's only 150 rpm before the power is cut.
My conclusion: The rev-limiter should be used to give the cars more character to improve their respective unique feel.
In short:
Think about what character the different cars should have and raise the rev-limiter for those cars that should be able to handle it.
