Weird scraping/clunking noise when turning left

[TrackAddict]

Hey guys, I finally got my E30 race car on the track. I'm very impressed with it but noticed that during hard left turns I can hear scraping and clunking noises coming from the right rear wheel. The clunking is almost rythmic but goes away once I start to straighten out. It almost sounds like a tire rubbing and the car riding on the bumpstops but I see no evidence of rubbing on the tires. It did get worse as the day went on and I could feel the "drag" of the right rear wheel slow the car down more than what you'd expect in a turn. Steering feels fine and the car handles well. No bad manners.

Does this sound familiar to anyone one? I plan on putting the car on a lift this Tuesday but would like to have an idea what the problem might be. Thanks for any insight.

Wheel bearing, half-shaft, or diff. You should be able to figure out what's wrong with the car on a lift.

I'm thinking wheel bearing or CV joint. I'll put her on a lift tomorrow. Here's a short movie clip of the car making a left turn.
