REALLY?!?!?! This is exciting! I would love it!

As for selections, I'm no pro as to guessing what torque splits would be best, but 4-5 selections total would be most desirable for me. My best guesses as to what the best choices would be is: 5%, 20%, 30%, 50%, 70%.

I'm assuming when you listed percentages you meant % going to the front wheels. So obviously 5% for as much power sent to the rear as possible. Now I won't confess to having as intamte a knowledge of the TOD as I'm sure you have now, but wouldn't 100% have the same problems as 0%? And honestly, I prefer power going to the back anyway. As for 20, 30, 70-- I'm just guessing, but I think some testing would reveal the best splits. The only reason I don't include 25% is because of all the cars I've seen/heard of with driver adjustable splits, I've never seen a 25/75 split
