EAC tuning failed to email me back about when their e39 coils would be back in stock. I need to rehab my suspension by the end of the summer. The PSS9 kit is out of the price range, and I don't like that the cheaper billys don't have adjustable damping. Anyone out there who has any advice I would love the input. I need a decent ride but am willing to go a little/decent bit stiffer than what my stock sport suspension offers. I would like to keep the drop to around 1-1.5 inches below stock sport height, and still be able to easily crank it up for the winter.
