Exotek F1Ultra extra stiff chassis & ball diff axle

For the F1Ultra, Exotek have produced this new optional extra stiff chassis designed for extra high grip smooth tracks. Made in the USA from 2.5mm quasi weave carbon fibre there is now also a new extra short wheel base setting (2mm shorter than the stock short wheelbase) and there is an extra chassis hole for 1/12 servo mounting. Also for the same car is a heavy duty steel ball diff axle. The 1-piece shaft offers maximum durability and also provides extra rear weight (shafts weighs ~26grams) for more traction in low grip conditions. Solid on the right side and hollowed on the left side to help balance the rear pod, the alloy diff ring mount is a direct fit for the F1Ultra stock ball diff.
