I was thinking about getting the ground affects kit, but I really do not think it makes much of a differance. Also, living in NYC having a lower ride will not last too long. POTHOLES!! They will take out that front fender in a sec! If down the line I see to get it I will, that is my two cents.
the GE kit is great i think, its not too much (ricey) and its not too little, it makes the tC stand out a lil bit more but not in a bad way, and well the factory fit, factory paint, factory quality, and factory installation is a huge plus
