Hi Rich,
No modifications and it took less than 5 minutes to mount with the level 1 aero Z06. With the larger Z06 splitter several fasteners have to be removed but with the base level splitter only the fasteners that go through the mount come out. I expect that it would be the same easy process with the Stingray or Z51 front splitter.

Saw the picture of your front plate mount from Top Flight in a recent post on the Corvette Forum. Did you have to do anything to use the Low Profile mount with the front splitter?
