In regard to having to sell off old t4 chassis stock, for some reason I have a feeling that wont take long at this rate. Is there an advantage to new vs old designs?

Has anyone tried this out on a smaller track yet? If so, is the stability more beneficial than the agility of the stock wheelbase?

If I give this a shot, I've considered doing some carbon plates to fill out the entire side areas with cutouts for the electronics . I know the vertical areas are where the strength comes in, but I thought it would look cool and with weight being added anyway, I don't see much downside.
