I have Steeda lowering springs on the '13 ST, and it has about 58,XXX on it with about 30,XXX on the lowering springs. Every time I get out of the car there is a slight squeaking coming from the rear of the car. What my concern is, is it the springs/shocks or could it be the parking break as i know that could cause a squeaking as it is used so often? If anyone has any insight on the matter PLEASE respond, any information is better then nothing. Thank you!
