Anyone see how Darkside deals with this issue on the 10th scale oval pan cars? It's a center-pivot bellcrank rack with a single trailing link arm to the servo. A nice alternative, but the larger cars have more room to do this with. Pretty slick idea, though.
I wonder if the zero-Ackerman/zero bumpsteer sliding rack that Custom Works designed many years ago for dirt oval could be developed in a 12th scale format? It's a flawless setup for 2wd dirt oval cars, no reason why something simple couldn't be adapted and designed for 12th, too.
