the hardest part was putting on the springs in the front cause I didn't have spring compressor, even intrax were a bitch to put on in the front. But not bad for honda guy to do it by myself. Sofar its my 15th lowering and by far the hardest I would have to say Lexus IS300 and WRX which I also did by myself. The new civic si was hard too because you have find the "sweet spot" to put the hub piece in the shock which means you have to turn the disk like a hundred times in the front.
