Could you possible tell me about how much you gained? This sounds like a damn fun project. I'll do this about the same time... damn what was that other project. Oh yea! Might do this about the same time as cutting the stock springs. Haven't really heard anything from that other thread saying that it is bad or good. Long as I keep it reasonable. So back to the original question.... bout how much in gains and how much more in gas milage?
Got a 1,000 mile trek planned for next week and this could help.
