The gearing change is a percentage so how much off depends on how fast you are going. I think the L99 is 20%. This can be accommodated by the driver, you just have to remember that you are going 20% slower than what the speedo says.

The big thing about gears is that you will be putting on 20% more miles then you really are and the shift points must be adjusted as well. The miles and the shift points is what most people worry about.
