call up wayne at eibach and have him recomend you a spring to put on it. Try that spring out first and if you dont like it then you should send it somewhere. I am 225lbs with a 6in swing arm and I like my stiffer spring alone. I think it rides great. There was no need to get it redone and spend another 300 bucks on it. So try it out first and see how you like it.
