im also with state farm and they told me that i am perfectly fine with "Body Modifitcations" kits etc etc, BUT! as soon as i change the center of gravity on the car they will cancell me, i am paying out the ass for my insurance, but we wont go there
also my broker told me that if i were to add any performance part to my car (engine wise) even air intakes then they would cancell the insurance.but with audio shit i was told they will cover up to 1000 in audio
