Wow, I'm floored! Thanks, overyeoj, for taking time out of your busy and dangerous schedule to help clarify this. So let me know if you got me on the correct track...A center diff is more predictable and tuneable, especially on rough tracks. There is also a difference between traction (wheelies) and forward bite (vehicle acceleration) in which the center diff also excels. In braking, the center diff loses the rears (hence the people rigging custom rear brakes), while the RD Quickturn loses the fronts.

Am I up to speed now, or are there still things I'm missing? It sounds like at LHR I need the center diff to be competitive with a lot of horsepower.
