Yes Evo 5 and 6 will bolt onto those factory recaro rails. 7/8/9 should too though I haven't tested. Evo 5/6 seats may sit higher that the super recaro using factory recaro seat rail.
Evo 8 (and assume 7 and 9) don't fit factory VR4 Recaro rails without a little adjustment. They almost do, but require enlarging/elongating the rear holes by about 3-4mm.
