Those sizes sound right.
Let me throw in my experience with Saturn brakes, if you folks don't mind.
I have driven many hundred of thousands of miles. (Lots of driving!) Of course, I didn't always drive a Saturn, so I was surprised when my '01 SL with 12,000 miles on it was pulsating like mad when I used the brakes. I had previously driven a number of cars for 90,000 - 110,000 mile stretches without rotor issues of any kind.
The Saturn dealer kindly replaced my rotors and pads, and everything was fine until I hit 24,000 miles. Again, Saturn replaced my rotors and pads with original equipment.
Guess what happened at 36,000 miles? You got it, pulsating brakes. I took the car to a different dealership who promptly accused me of having poor driving habits. I knew this was a load of crap because I've had no problem with rotor warpage at any other time in my life. So, I took it upon myself to figure out the problem.
I measured my rotors and discovered that they were not warped. Instead, they seemed to be thicker in some areas. This turned out to be caused by deposits from the brake pads. The deposits were invisible, but they were still there. I tried a new approach. I replaced the rotors with new units from Saturn, but this time I installed some basic organic Raybestos pads from the local NAPA. At 48,000 miles the brakes were still perfect. I declared the problem solved at that point.
Around that time, my car was stolen. It was not recovered and returned to me until four months, and another 20,000 miles later. The brakes were trashed as badly as the rest of the car, and the rotors had cracks forming in them. Even with that kind of damage, the brakes didn't pulsate during cold stops, which told me that they certainly didn't have deposits or serious warping of any kind.
From my experience, I have concluded that Saturn rotors are good. Their semi-metallic brake pads, on the other hand, seem to blow.
I won't jump on the anti-Saturn brake rotor wagon. I will continue to use them until I see a need to use a different brand of rotor. I will, however, be very careful about what pads I choose to use.
