Buddy of mine just sent this to me. Great read. Enjoyed it a lot and couldn't agree more. Dinan packages take the car to what should have been available as an option from the factory. Yes it is available from the dealership [if they offer Dinan products] and I am sure any BMW Client Advisor worth his weight in gold would be happy to add them to your final sales sheet. But still it seems the F10 550i chassis offers a lot for those willing to tune it to improve a pretty nice product in hand. If they ever offer something for the F10 M5 wow it'll probably make an even great car...that much better.
Well enjoy...and please lend your comments/experiences/pros and cons are all appreciated.
