Search dude, there is a great write up Tony (ATHOXA?) did that we all added to somewhere on XOC.

Install is pretty straight forward. AC 2" BL went on my X really easy and has been solid for the last year. The bumpers relocated very easily as well and look fine. I only have 31's for tyres so I can't speak much ont he clearance issues of bigger tyres yet but personally it looks great! For me it came down to money, I didn't want to replace/upgrade any steering components at that time so I went for the BL as it is quick and easy and can always be useful in the future. A PML will prolly be in the works for me this year, but a full blown SL is a little pricy for me now. You can't loose with a BL if you are willign to take your time and relocate the bumpers and stuff properlly.....or just live with the gaps
