Sounds like you did your research, saved some $$ AND picked the right installer:thumbup:.true, i do want it done right and thats y i choose a shop in hoouston called lawell motorsports. they do alot of high end car performance and was cheaper then most shops in the area. i'm looking at 500 with alignment. other shops were 800 and 950. they also have done the m5 body kits on 530i's and thats my next move. i keep you guys posted and put up pics.
