I used the shims. They held up for about 1.5 years before I started to get the high speed squeal badly.
I added some brake quiet to the them last fall when I had everything apart and that lasted for maybe 6 months and the squeal came back.
Yes I am very hard on my brakes.
The front rotors had glazing when I took them off last fall so I "roughed them up and that renewed them for a few months.
Looks like I'll be doing both again.
No pulsation in the pedal and the brakes still have that great initial bite.
Fade has increased slightly but I blame the overworked rotors for that at this point.
Next time I buy front rotors they will be bigger then stock. Be it the 300mm FSVT or some nice 2-piece 12.2" discs.
