Stock mirrors are driver's side flat, passenger side convex. Aero's are both convex, same degree of "convexity" on each (can be swapped side-to-side), but degree of Aero convexity is less than degree of stock mirror convexity.
On driver's side, Aero extends field of view approx 60% (subjective guesstimate) over stock mirror, but on passenger side, only about 20% over stock -- probably because of the differing degrees of convexity between stock & Aero.
To put it somewhat differently, with the Aero's I can SEE vehicles way closer behind me on driver's side than on passenger side - regardless of how close they APPEAR in the mirror. The passenger side has a much larger blind spot, with or without the Aero's.
