Not quite motor sport, but some could argue ? You've got to watch this video, from SCA, & our two friends Marty & Moog, from Mighty Car Mods.
Watched it, & recognised the setting, as it's a road I use it quite often, as a short cut/scenic drive from Beaudesert to Grafton, via the Lyons/Lions Road just north of Kyogle in NSW.
