I did a post here awhile back featuring various front lip spoilers you could choose from for an E93. This time I've compiled several options for those interested in personalizing the rear of their BMW. This is a modification I'm currently not interested in until I look into doing a complete exhaust upgrade to a quad exhaust sytem, something I may do in a year or two. Right now I'm enjoying the "golf tee mod" sound boost I did last week.
Back to the rear options for a different look. Here are some of the looks you can get if you pursue this modification. My personal favorite is the RD Sport. I think it looks very clean.
