We have a Gen1 Gtm. We had our hearts set on the Ace R1 18x9.5-53mm and 19x11-63 but they have been discontinued and I can't find them anywhere. Our second choice that is the new Cray Brickyard but no one is able to confirm that 18x9-50 or 18x9.5-56 will clear the C6 Z06 brakes. Any help would be appreciated with this fitment or other (subjectively) good styles. We had been focusing on reasonable cost $1-2k but now may have to go higher...
