The 2013 Chevrolet Camaro SS rides on the Alpha platform with a 5x120mm bolt pattern and a 66.9mm factory hub bore — two specs that define your entire wheel selection on 5th-gen SS builds. Running 20x9.5 / 20x10.5 wheels with 275/35R20 / 305/35R20 tires and an offset in the +35 to +45mm range puts you in proven territory for this chassis, but there are critical clearance details to confirm before ordering. By 2013 the 1LE package was well-understood in the community and fitment data was more refined. The 1LE track package runs on staggered wheels with a contact patch optimized for corner entry stability. If your 2013 SS has the 1LE, treat its factory stagger as your baseline and only adjust offset if you are running a dedicated track setup. For street builds on non-1LE cars, the staggered approach still applies but offset choices loosen slightly since you are not managing tire shoulder wear at high lateral G. For the 20x9.5 / 20x10.5 combination with 275/35R20 / 305/35R20 tires, confirm inner barrel depth against the Brembo caliper by measuring from wheel mounting face to the inner lip edge. A wheel with insufficient clearance will contact the caliper during steering lock on the front axle. Rear fitment is more forgiving on the SS due to the IRS layout — unlike solid-axle Camaros, the independent rear suspension means no pinion angle penalty when you widen the rear contact patch. The +35 to +45mm offset window listed here accounts for fender liner proximity under full compression, not just static ride height.
