- The industry’s original deep concave forging, developed by ADV.1 in 2009.
- Provides a deep concave profile up to 5″ for some applications.
- Deep lip application using ADV.1’s “leg extension” option
- 3 piece forged.
The ADV.1 Deep Concave configuration. Similar to our flagship line, the Track Spec Series, the Deep Concave option consists of a 3 piece construction using our deep concave profile forgings with a modified die designed to allow what we call a “contoured spoke leg extension.” This feature allows us to engineer each spoke of the wheel specifically around the exact contour of the step lip outer rim profile.
