Also switch to a carbon fiber brake rotor setup as those huge cast iron rotors on the E-Tron are quite heavy (retrofit some Porsche PCCB's), that would make a considerable difference not only in the suspension but in the steering feel, acceleration and the range.
Should be able to do both of the above for about $ 30,000 <g>
