Theres a few lip kits out there and if remember correctly some tc’s r optioned with stock 18’s. Theres a few performance mods out there that will still keep the car under the warrenty(i think there is a supercharger?). A friend of mine has 1 and it is comfortable but the seats in the back for some odd reason dont have much cushion and tend to hurt my back if im sitting there for 30+ minutes. I still like the car though. One nice thing i like is that there is that door that covers the radio. Its nice to have cause if you would want to put a in dash nav screen/dvd player it would be covered buy the door. Power wise it doesnt seem bad for a compact car. IMO id go with the tc
