Within the last year, the Technical Editor of the
Roundel produced an extensive report on a full Dnan upgrade of his 3 series. Because it involved a good many hardware changes as well as software upgrades, the accompanying photos are extensive. A discussion of what makes Dinan Dinan, from inside the shop over the course of a week vs. via marketing blurbs, was highly informative. I believe this issue is still online with that article available, altho' I notice BMW CCA also offers back issues for sale. If you're thinking about sourcing aftermarket products, choosing the supplier is a key step...and as mentioned above, Dinan is obviously one vendor to consider. In which case this article is well worth your time. (Not a CCA member? Tsk tsk... <g> )
