This upgrade set is designed to take the performance of the FF-03 chassis to the next level. The newly designed carbon lower deck features a narrow design with the separate mechanism decks positioned on each side to enable a greater roll movement range during cornering. Refined IFS (Inboard Front Suspension) setup has front dampers positioned longitudinally like the TA06 chassis to achieve better weight distribution and the new long tie-rod steering system provides smooth steering feel. Vertical double frame and aluminum bulkhead stays straddle the battery section to increase overall chassis rigidity and make quick battery replacements possible.
