It is really a complete peice of cake m8. If you have the 2 pot brakes there are three 3 bolts to remove, if you have the 4 pot then there is only two 2 bolts to remove. Very easy to do.
The old discs may be stuck on the hub, depending on how long they have been on for, a quick squart of wd40 on the old disc on the lip just outside the main wheel bearing nut should loosen it, tap from back with a hammer to easy it off.
Fitting is the exact of removal.
It will take you a while to do one side, when you get to the other side it will seem like it only took 5 mins.
