I've got the 5 way street shock, not the drag. There is also a drag version, or at least there used to be.
On the street one, I run 3-2 or 3-3 Front/rear, with stock springs. 5 is extremely stiff and I can't imagine using it on the street. The shock becomes stiffer than the springs. At any rate, 1 on the fronts is weaker than stock, but not as weak as a drag shock.
The Drag Illuma offers 1-3 drag, and 4/5 are more close to stock. Whereas the Street/standard version 1 is slightly weaker than stock 4/5 are stronger than stock.
Hope this helps.
