At the end of the day it comes down to personal preference but there are certain builds that may be more cost efficient or reliable than others. Show cars, however, truly are about preference but the route described is the one I would take, along with many other modifications in the future.
The daily driver set up will have a softer ride while still being more attentive than a stock fiesta ST. The Track car setup is significantly more aggressive and builds upon the daily driver platform. The track car however would use suspension that doesn’t improve ride quality. The track car would necessitate springs that would improve handling while removing ride quality; while the daily can run springs that improve both over stock.
