The 2017 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. The 2017 Camaro SS 1LE reached full maturity with the Multimatic DSSV passive dampers — a track-focused suspension setup that altered optimal wheel geometry compared to the base SS spring/damper package. If your 2017 has the 1LE, the factory stagger of approximately 20x9.5 front and 20x10.5 rear with +28mm front / +19mm rear is the calibrated baseline. Moving to wider rear wheels improves grip but requires verifying inner fender liner clearance at the rear quarter since the 1LE runs lower ride height from the factory. 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.
