I went to see how much the dinan suspension would cost and it is close to $1800 for a stage 2 kit. This seems a little overpriced for what you are getting. I know that the warranty is a big issue, but it looks like I could save a lot of money having non-dinan parts. Comments? You COULD have a Dinan suspension (or if you want to AutoX in STOCK class, then shocks and front swaybar only) put on the car and SOLD to you that way. Then it would all be covered under your car loan and not out of pocket. And as it would be Dinan parts, it would be covered under warranty (Dinan's, but would be the same as BMW's). That should take care of the soft suspension for you.
