you can not do anything to alter the cars suspension, engine, basically anyway the car works and performs you can not change because you are taking a chance, because if something goes wrong honda will not pay for it. Also if you are thinking of puttin something on and then something goes wrong because of it and you change it back honda can still tell because when they hook your car up to the computer it will tell them what has been touched and what hasn't. Just a little info to keep you out of trouble.
Thanks,
