Front passenger side. I had just gotten to school for one of my night classes, was parking and felt a bump, then heard a funny noise. Got out to take a look, noise was the tire rubbing the inside of the fender, passenger side looked slammed/ 'hella flush'. Body was literally sitting on the tire. Good thing my cousin had a Z32 at the time. After class I got a ride to his house and we stole a control arm off his Z. Back to school parking lot to change a control arm in the dark to get my Z home. Fun times. Really glad it didn't give out on the freeway while I was driving to school that night (or any other time while driving). It was probably a hair line crack that progressively worsened until failure. Not a bad idea to take a quick look around when your Z is in the air.
