it still has negative camber dude, just havent measured how much yet, if you want more then you need to use whiteline camber bolts or alike
the old ones just knock out with a hammer but you need the hub a certain way so there is room to get them out. the new studs are easy mate, i just tapped them in from the back a bit, then used a 19mm 1/2 drive socket over the stud, then put an old wheel nut on the stud and it drags the stud in when you wind the nut on
