We ran 1/8 drop with blue nitrile in both 2013 (6 wheel WCD long base) and 2012 (10 wheel center 6 dropped wide base) and ran it with a 1/16 drop this year (wide base 6 wheel WCD) all wheels being between an inch and an inch and a quarter. We haven't experienced any turning problems, but one of the things we are hoping to look into this summer is playing around with the drop amount.
