They weren't revalved for these spring rates, however these rates are not far off from what they came with from KW. I've spoken to KW directly, and Harold at HP Autoworks and many others have had great success running varying spring rates on these dampers. If we were talking an extreme setup like 700lbs front and 1000lbs rear, I wouldn't advise it, but 450/750 is nothing.

Both my e82 and e90 were sorted, smooth and extremely capable on this setup. I hold platform records (or close) at a few of the tracks out here on this very setup.
