I utilized the jack that came with the car, however, I have a 2 ton bottle jack that I used as a redundancy because the wheel was off the car for about 15mins. I didn't trust the factory jack to hold that long since it is mostly for taking off a wheel and replacing it with a spare.
The total project for all four wheels was a little under two hours (about 30 mins per wheel). Of course each wheel had to come off, wash, wax, and replace.
Additionally, for SAFTY I used wheel chocks and for SPEED I used a breaker bar. The wheel lugs are 17mm if you want to buy some sockets.
I would rate the project as simple as long as you take your time and be safe.
