Have some questions about how to achive better handling and stopping power using different springs, upgrading to coilovers, questions on swaybars, bushings, different rotors, pads, ect... Having any steering problems or questions about steering racks, tie rods, tie rod ends, ect... ask these questions here.
They are an upgrade. They can handle a drop of about 1.5" IIRC and still be covered under their factory's warranty. I'll have to check the warranty card I filled out when I got mine.
