Engine Upgrade
As a recent new z4 owner, I'm looking at all my modification options and have picked out a few things but have the main choices or major options still to make. In regards to the engine, I've been told to look at Dinan stage 1 and 2 to begin with or JB4. What suggestions or recommendations does anyone have for either of these upgrades? Any stories of personal experiences would be very helpful. Thanks for the information, anything to help me decide would be deeply appreciated.
