I tried to search and could not get my piece of crap computer to work, so I apologize for that in advance if this is a common question. With a 1.5" rear block will I run into issues with brake line lengths, or shock lengths? I'm going with a 2.5" front leveling kit, and want to do a 1.5" block to try to retain the stock rake or close to it. Going on a 2005 CC XE 2wd Thanks in advance!
