ah, I remember that thread Don. I spoke to them and i remember them telling me it was easier to set-up the sumo suspension than many jag based cars as they knew what they were looking for and there were less opportunities for builders to get it completely wrong. Lots of people went down there I think and all said it made big difference. I never did as I had already made plans to sell my car so it didn't seem worth it for me at that point.
