Anything changed that is attached to engine like what you mentioned, exhaust etc. will void engine warranty. Suspension usually will be drive shaft claim.i was told that if i do anything to the engine,exhaust or suspension then warranty mati.bodykit no problem.even if just change muffler tip also mati.but a friend of mine told me strut bar no problem,because in case anything unsavoury happens,can quickly cabut before claim.=) but if i were to do anything,ill probably do it after i come back next year lah.=)
Not only mod., today wife sent her SUV in for service, and ask if can bring own oil, because theirs, raise in price again, and they mentioned will void warranty......true.true.nevermind lah.after warranty finish then mod.=D
