The 2015 Chevrolet Corvette Stingray C7 enters its second production year with the same core fitment spec as the 2014 launch. Bolt pattern: 5x120mm. Hub bore: 70.3mm. Stock: 18x8.5-inch front ET+56, 19x10-inch rear ET+56, 245/40ZR18 and 285/35ZR19 Michelin Pilot Super Sport. The 2015 model is the first year the Z06 and Z51 packages fully validated the wider tire fitment window on the C7 platform — Z51 uses 265/35ZR19 front and 295/30ZR20 rear on 19x9 and 20x11 wheels, useful reference data for base C7 owners planning fitment builds. For base C7 2015, the confirmed safe front offset window is ET+48 to +60 on 18-inch, clearing the standard 355mm Brembo six-piston with 94mm caliper clearance. Rear: ET+48 to +60 on 19-inch. Wider-than-stock tire on base C7 rear: 295/35ZR19 confirmed on stock rim; 305/30ZR20 confirmed with 20-inch Z51-spec rim swap at stock alignment; 305/30ZR20 or wider requires -1.2 to -1.5 rear camber on base suspension to avoid inner liner contact at full compression. The C7 front splitter — longer than C6 — creates a minimum ground clearance limit that restricts total lowering to 25mm before ramp contact on steep inclines. Track builds address this with motorsport-spec adjustable front end links. C7 bolt pattern 5x120mm applies across all C7 years 2014-2019.
