I found another vendor selling them , they want $1,700 per rotor.

I have a slight vibration at 75. I can live with it but would prefer a fix.
Road force balance on my cup 2's did help some.

For what it is worth I feel the PS2's are a major contribution....AND tire shop balancing with 20lb of road force and call it good when it should be at 10 or less....

I've got 18 track days on my rotors, which were almost vibe free before I started tracking it (after GM replaced the rotors and the front tires) and I can tell you, even with my aftermarket wheels with Nittos or stock wheels with R888, it has never come back....(though seems to come and go when I ran the PS2). you'd think if it was a "rotor issue" it would come back especially when you track the car and actually "wear" the rotor but so far so good....
