Bought these 2 months ago. Around 1k miles. Everything is in excellent condition. The kit provides noticeable lowering while maintaining proper suspension travel and everyday driveability. Read more here: http://www.dinancars.com/assets/File...%20REV%20B.pdf
Reason I am selling: moving on to Motons.
$720 shipped (MSRP $999).
2 front springs
2 rear springs
2 shortened OEM front guide supports
2 shortened BMW front bumpstops
Installation directions/alignment specs
These can work on a E90, but Dinan recently updated the sedan kit slightly to have less drop in the rear. However, I have not heard of any problems from those who have the original sedan kit.
PM me if interested.
