The Steeda x2's are great especially if you are lowered, anything you can do to get the a arms back closer to perpendicular is well worth the time and effort spent. Also, if you want your front end a bit lower, you can not use the spring spacers the x2's come with and they will actually drop the front down by about a half an inch. I left the spring spacer it comes with out and went with full poly iso's top and bottom which ride oh so nice!
Also, for the record the terminator a arms don't actually give us any more steering angle as our tires will rub on the sway bar long before they rub on the part of the a arm that was redesigned. But, they do have very nice higher durometer (stiffer) rubber bushings in them that will give much better steering feel and help with tramlining if you have fat front tires like I do
