HPI Racing have released a whole bunch of option parts for their new Formula Ten chassis. First up is this ball differential set that allows you to quickly and easily tune the differential to track conditions for optimal handling, the smooth and efficient diff action gives extra traction for lower lap times. Also new is a lightweight aluminum shock absorber that is threaded for precise spring adjustments that allow you to quickly tune the handling of your car to track conditions. Silicone oil is included, along with a track-tuned spring, machined 3-hole shock piston and a knurled adjustment ring. For the front there are lightweight aluminum front axles which are fluorine coated for reduced friction and semi-hollow for critical rotating mass weight savings that give your car quicker acceleration and better handling. Finally there is a bunch of orange anodised aluminium parts such as a servo mount set, motor mount, left bulkhead and rear axle shaft.
