I did notice a difference in sound between the two although, the suspension is different on both and I was wondering if the spring rate differences are the reason for the BRZ riding ALOT smoother than my 14 frs monogram. I would like to point out that I compared my car with the same equivalent 14 limited brz. Anyone have any input on this? I have the springs off of a BRZ and was wondering if this would make my car ride at least noticeably smoother and less quiet?
