Your axles will most likely break at the launch but not throughout the run...

By adding an LSD, you will distribute the torque to both axles instead of the one that slips...Its this distribution of torque that snaps your axles...I've learned that Honda Trannies are strong and can last a long time with proper shifting and maintainence...I wouldn't worry about the GearBox, Instead, I will keep a set of axles on hand and keep maintainence up as usual...Grinding the gears and Power Shifting, shifting without lifting off the gas pedal, will lead to premature tranny failure...

AWD Cars suffer from broken tranny parts because the wheel slip is near absent...This leads to only one thing and thats a shock to the Gearbox and thats where you have your problems...

Just remember to use as soft a clutch as you can get away with and the part of your clutch that really matters is the Pressure Plate...
