Hey all just recently I've started noticing that after driving my 8 for a while whenever i start off from a stop it feels like the brakes are locking my tires or something its real jittery and has like a scrubbing sound that i can feel in the back tires i usually really have to run the rpms on up to make it smooth. Any idea what this might be?

 

warped rotors?

 

Parking brake stuck on or slave cylinders sticking or bad motor mounts.
