The point of contact (traction) is ultimately the tires. If you're
launching the vehicle (hard launch) the transfer of torque is greater with
the 3.55's as compared to 4.10's. Since the tires are the weak link here,
they will be the first to let go. The 4.10's (or 3.90's) soften this
effect and will allow faster starts with a less chance of traction loss.
Now with more HP (and TQ) coming from the engine, any size gears won't help
if you can't control the tire spin. (That's up to the driver...not the
vehicle.)
So...Can we finish this up and go out for a Beer yet? ;)
