Whats the process of changing studs?

All you do is hammer them out... A couple good whacks with a 3 lbs sledge, and they will pop right out. I use a wheel stud installation tool, but you can use a very large nut, and a SPARE lug nut. Just put the stud in, put the big nut on, then thread the correct SPARE lug nut, and use an impact gun to pull the stud into the splines. Usually after a couple studs, though, the nut becomes a little too screwed up to use again. Make sure to go slow... Hit it a little at a time with the impact gun to keep the heat down in the stud/lug. Too much heat, and the threads will start coming apart. If you have no impact gun, take it to a shop, and they shouldnt' charge too much.. Maybe 50-100 bucks to change all the studs on the car. Hope this helps.

I believe the front require enlarging the holes -- IIRC, nobody makes a direct fit long stud.

The rears are easy to come by.

Moroso does!
