yeah, you just run the brake lines from the caliper to the hard pipe in your wheel well (like a foot or so). I don't think your LX brake lines will fit though... try and find some integra ones.
I'm not sure where the prothane bushings are sold. the crossmember isn't actually *installed* sorry for the confusion. It just comes with a new crossmember so you don't have to strip all the rubber off and re-use your stock one. Really the hardest part of the bushing job is just stripping all the stock rubber out, so whatever makes you do less of that, is :thumbup:
