Tunneling between two-dimensional electron layers with mutually correlated disorder potentials is studied theoretically. Due to this correlation, the diffusive eigenstates in different layers are almost orthogonal to each other. As a result, a peak in the tunnel I\text\ensuremath-V characteristics shifts towards small bias, V. If the correlation in disorder potentials is complete, the peak position and width are governed by the spin-orbit coupling in the layers; this coupling lifts the orthogonality of the eigenstates. The possibility to use interlayer tunneling for experimental determination of weak intrinsic spin-orbit splitting of the Fermi surface is discussed.
