I have been seeing a good number of those lately on the road....I always forget which car it is and im like "thats a nice car" then to my suprise I see its a Scion...very nice.
Took the tC through some sweepers, and the tC really can benefit from a strut tower brace, sway bars, and lowering springs(lowers center of gravity=stability).
I'll let you guys know once I beef up the suspension, a have a great base to work with.
