I’ve been running Doug’s ( http://www.dougshelbyengineering.com/ extreme extreme splitter extension on both my ACR and 2013 9 liter and love them. I had him recently make one slightly smaller (1″ bigger than stock) (the biggest one is 2″ bigger than stock). Both of my cars are very well balanced, but I’ve always had a bad understeer problem at INDE. The big extension really helped, so had him make me one in between just to try and it seemed to work just as well so I’m sticking with this one permanently. (By the way mods you guys really need to do an iphone X pic orientation patch). I’ve posted pics of the extended strakes before, but added a couple down below
