New for the Atom 2 GT12 from Schumacher is this spool set, incorporating single bolt fixing hex wheels. This Option Part is specifically designed for medium to high grip conditions and helps improves direction change, on-power steering and predictability in high grip conditions. Whilst being drastically lighter than the kit differential, this set offers a weight reduction compared to the Core RC 3 bolt option as well, and therefore improves acceleration. The new hex wheel design offers improved flexibility characteristics and performance while the single bolt fixing makes changing tyres faster, and maintenance is also greatly reduced compared to the differential. The weight saving of this option compared to a diff is 16.8g. This option part makes use of the new ‘Hex’ style Contact wheels with versions available with 35 and 40 shore as well as the 37 shore control tires.
