Beam Offset

[AdamP 0]

Had my first sprint of the season yesterday, car was handling really nicely, then on the 4th run there was a loud bang, sounding like something giving. I thought it could had been the weld on the ARB giving up but it didn't appear to adversely affect the handling. When strapping the car on the trailer we found that the drivers side rear wheel is pretty much rubbing and the other side has a 10-15mm gap. Now i'm pretty sure it wasn't like this when we strapped the car down to come! Had to go straight back to college so couldn't look over the car at all, what are the chances of it being a beam mount giving way or something? There doesn't seem to be any extra camber or anything.
