Was having a wail of a time and pushing quite hard in an effort to carry as much speed as I could through Paddock Hill bend. Literally 3 or 4 seconds max, from hitting the brakes, before turning in, the back of the car slewed to the left and I struggled to keep it under control. The reason for this was that the nearside rear tyre had let go in a major way.

At first I figured it was just a regular puncture or that I had just pulled the tyre beading from the rim. In fact, the reason for the blow-out was that the inner tyre wall had been rubbing, ever so slightly, on the lower spring cup. As the suspension compressed and negative camber increased, the tyre wall moved in with the obvious results.
You can clearly see where a groove has worn around the tyre wall circumference.

As a result I need a shorter spring that will allow me to move the spring seat higher and out of the way of the inner tyre wall.
I thought I would mention it here as I know a lot of us run with Gaz coilovers and I would urge you all to check and make sure you are not also suffering with the same problem.
Obviously, I am fairly new to the whole coilovers, set-ups etc etc so have I done anything that would have contributed to this problem? Apart from shorter springs and having the rear subframe modified, in order to lose negative camber, is there anything else I could do. I really don't want to alter the ride height as the car needs to remain able to cope with speed humps.
Any ideas please guys?
