The 2021 Chevrolet Camaro SS is 6th-generation Alpha architecture — a comprehensive redesign that kept the 5x120mm bolt pattern but changed the hub bore from 66.9mm to 65.1mm. That single-millimeter shift matters if you are swapping wheels from a 5th-gen SS or shopping used wheels from that era. The 6th gen runs 20x9.5 / 20x10.5 wheels with 275/35R20 / 305/35R20 tires, and the +35 to +45mm offset range on this page is tuned for the revised suspension geometry and wider fender opening of the Gen 6 body. 2021 Camaro SS fitment is identical to the 2020 spec — 65.1mm hub bore, 5x120mm, Brembo 6-piston fronts. Notable for buyers: the 2021 and 2022 model years were the final years before GM announced the Camaro's discontinuation, which has driven increased interest in track builds and full wheel/tire packages on these cars. Offset selection in the +35 to +45mm window provides adequate fender clearance under aggressive driving conditions without requiring wheel-arch modifications. With 275/35R20 / 305/35R20 on 20x9.5 / 20x10.5 wheels, confirm that your tire's section width does not exceed the wheel's intended width range — running a 335 tire on a 20x11 wheel, for example, is at the outer edge of the acceptable mounting range and may roll the sidewall slightly outward, affecting handling precision. The IRS rear suspension on all Gen 6 SS cars is tolerant of wider rear fitments, but inner liner contact under full droop should be checked with the car unloaded and wheel at full rebound travel.
