Are there differences between OEM and replica ZR1 wheels?

Curious about it for bigger brake clearance. I like the new Wilwood kit that Sam Strano offers but am not sure if it would fit aftermarket ZR1 (c4 style) wheels like it did his stock SS wheels. I know he had to use spacers but OEWheels website says they will not fit upgraded brake systems. Anyone know if the inside of the wheels are different?

OEM '96-'99 Camaro SS wheels were a 17x9", 50mm offset wheel. Most (but not all) of the repro "SS/C4 ZR1-style" wheels were/are made in a 17x9.5", 56mm offset (this was stock rear sizing on late C4s, and also front sizing for the Z51 cars.) In addition to this size difference, there have been multiple versions of the repro ZR1-style SS wheels, including deep dish and "squared-off" spoke versions (where the spoke meets the rim portion is more of a defined edge on newer repros, vs. a rounded shoulder on the OEM and early repros.) However, I can't say for certain whether or not the inner spoke design would be different enough to cause fitment issues in this application.
