Best in the "Racer" area.
Presumably the "flexy" chassis is for bumpy plastic tracks, as against a hard chassis for smooth wood.
Tyres look interesting, more info please, though I am about to try mine with SC2009 20.5 x 11 foams that JUST fit under the arches !! Could be interesting with the Flat 6 R and Slot.it pod with 1.00mm offset, and Slot.it wood guide.
