I installed EPI front springs last month. I've only ridden once since, but overall I'm pleased with the result so far. The ride seems much more stable, although a little stiffer but nothing too harsh. I don't use a plow or load heavy, but the factory springs would always bottom out and the bike would dive going down hills or stopping. I did have to crank up the back springs to the next setting to level things out since I gained 2 inches on the front.
