Just wanted to let everyone know these guys are a stand up bunch. I disassembled my 823s so I could do a little more port while work they were off the car. I was unaware two of the inner springs had failed. A very unusual failure I've never seen. I gave them a call, no questions asked two new springs in the mail. All they asked was I returned the two broke enter springs for examination. No clue as to why the failure occurred as I was within the maximum lift the springs are advertised to handle. None the less new ones are in the mail and I was more then pleased with the way they handled it.
