Clunking Noise when hard right Braking
 

I have just recently noticed a clunking noise from the rear of my 99 986 with 72k miles when hard right turning. Is this likely the motor or transmission mounts?

Mine were the parking brake cables that rub on the inside wheel weight. The car toes in on brake weight shift and cause my parking brake cable to rub on the wheel weight. I saw shiny area of the parking brake cable. I used zipties to fix mine. I put one on the cable as a "stop" then another to pull tension on it away from the wheel.

Lots of possibilities for clunking though. I have motor mounts on hand to change now. They are not horrible, but I am doing a refresh on my 2001 Boxster S with 107k miles.
