ok, we bought a 2006 premium GT with the 6 year 100,000 mile extended warranty on it. now we are having it lowered. my ? is, by putting the lowering spring on the car, what exactly will this void warranty wise? or is it going to be only the spring? we are using the Ford Racing lowering spring, but it is not factory. i know if something fails on the car, the mods have to be proved to be what caused the damage, or else the failure is under warranty. so is there a reason to be reluctant to lower the car? or go for it?
