Necroing an old post instead of creating a new one. There's more and more drift tracks popping up all over the US now from California to New Jersey, from Florida to Seattle, and many, many more in between . I have four within driving distance of me for instance, and I know of a great many more across the US and Europe. And there's lots of new websites that just cater to the drift scene, like Super G, Slide Dynamics, Drifted.NL etc.
With a lot of new manufacturers popping up, Like Reve D, and a lot of older ones now making dedicated drift cars, like Yokomo, Redcat and MST, and with drift cars having quite different dynamics to on road TC cars, a sub-forum would make sense now, more than it did in 2016.
