...by a mile.
The DINAN 19's are stronger (8000 TON FORGED), lighter (20lbs, each), and more unique than the HRE monoblocks. (which a number of other forum members have already)
They also come with a beautiful polished outer wheel lip that contrasts the black spokes.
If you buy the HRE's, you'll be just another guy with HRE monoblocks. (nothing special)
But if you buy the DINAN wheels, you will definitely stand out. (very rare wheel)
It's not even a close call in my book.
BTW: The lack of any real concavity on the HRE monoblocks is very disappointing for wheels that cost 5-6k IMO.
