i go back from Chicago to Guadalajara on May 17th along with the brand new drilled and slotted front rotors for my 07 from R1Concepts; a few days later the mechanic replaced the OEM rotors along with new Ceramic pads from Perfect Quiet,
After reading the new rotors seasoning and break in procedure in this forums several months ago, drove to a slight traffic new avenue, performed the procedure, went back and let the brakes to cool off for several hours, next day I drove for 200 mi, first 150 flat and long straight Hwy, not too much braking except on the toll spots, last 50 mi the Hwy becomes twisty and climbing over a mountain range, that part always produced the infamous pulsing or vibration, under "spirited driving" no more, it is really gone!
After a week I drove back, this time downhill twisties for 20 miles, nice road, and actually a favorite spot for the Hwy Patrol using the radar, since it is very easy to go above the speed limit of 110 kph (70 mph ) I used the brakes more than usual just to test, not the slight vibration showed!
As for braking power, seems the same to me, no complaining on that ares before, just the annoying vibration on the steering wheel.
Totall cost was around $250 with ceramic pads for the 4 rotors, still wondering why Acura didn't care about this well known issue.
