Saturn Sky Wheels and Rims

Saturn Sky Aftermarket Wheel Fitment

The Saturn Sky is Saturn's rear wheel drive two-seat roadster, built from 2007 through 2009 on GM's Kappa platform. Element Wheels measures fitment on the 2007-2009 Sky, which covers the base 2.4L Ecotec roadster and the Sky Red Line turbo. Every Sky in that range shares the same hub: 5x110 bolt pattern, 65.1mm hub bore, M12x1.5 lug thread, 5 lugs. Important moat note: we no longer offer staggered wheels on the Sky. The rear axle nut on the Kappa platform sits 37mm proud of the hub face and prevents the centercap from seating correctly on a staggered rear wheel without the wheel poking past the fender. We measure square only on this platform. The Sky diameter window runs 18 to 20 inch. Pick the catalog row below.

Find Your Saturn Sky Generation

The 2007-2009 Sky is the only generation Saturn built. It ran on GM's Kappa platform for its full production life. Both trims (base 2.4L roadster and Sky Red Line with the turbocharged 2.0L LNF) share the same hub. Production ended early in 2009 when GM wound the Saturn brand down.

The Saturn Sky Bolt Pattern

The 2007-2009 Sky uses a 5x110 bolt pattern with a 65.1mm hub bore and an M12x1.5 lug thread. 5x110 is the small-car GM Euro-style pattern from the era. The Kappa platform Pontiac Solstice (2006-2009) is the Sky's direct platform twin and uses the same 5x110 / 65.1mm hub. The Opel GT (2007-2010) sold in Europe is the same car as well with the same hub spec. Outside the Kappa family, the 5x110 / 65.1mm hub also appears on the Epsilon Saturn Aura, the Pontiac G6, and the Chevrolet Malibu of the same era, though those are larger front wheel drive cars with different fender geometry.

Important distinction: the Sky is 5x110, and is not the same as 5x114.3. The two are different bolt patterns and sit about 4.3mm apart on the hub circle. A 5x114.3 wheel will not start on a 5x110 hub. The 5x4.5 imperial nickname refers only to 5x114.3 (114.3mm equals 4.5 inch) and does not apply to the Sky. Confirm any wheel listing says 5x110 before ordering. Compare across the rest of the Saturn lineup at our Saturn wheels and rims hub.

Why Saturn Sky Fitment Is Square Only

The Sky keeps the same hub geometry across every trim and model year. The base 2.4L Ecotec roadster and the Sky Red Line with the turbocharged 2.0L LNF share the same 5x110 bolt pattern, 65.1mm hub bore, M12x1.5 lug thread, and brake package on the catalog. The Red Line differs from the base car in engine output (turbocharged 260 hp versus 173 hp naturally aspirated), suspension tuning, and trim, not in wheel fitment. A wheel that fits a base 2008 Sky also fits a 2008 Sky Red Line.

What changes Sky wheel buying from other small rear wheel drive roadsters is the rear axle nut. On the Kappa platform the nut sits 37mm proud of the hub face. On a square fitment with our measured offset window, the centercap clears the nut and seats correctly. On a staggered fitment where the rear is wider and the offset moves outward, the centercap cannot clear the nut without the wheel sticking past the fender. We measured this directly on the Kappa chassis. We no longer offer staggered Sky setups for this reason. The diameter window we measure runs 18 inch on the low end up to 20 inch on the show-build end. 18 inch is the factory size on the Red Line and the most common Sky aftermarket choice for everyday driving.

Every wheel we recommend is backed by our Fitment Guarantee. If a wheel does not fit, we pick up the wheels and refund 100 percent. No risk to you.

How We Confirm Fitment on Saturn Sky Wheels

Element Wheels measures fitment on the Sky directly, across the base roadster and the Sky Red Line turbo. For the Sky that means hub bore confirmation at 65.1mm, clearance from the wheel to the fender on a stock-height car, gap between the back of the wheel and the suspension, brake caliper height at the standard Kappa spec, lug seat depth, lug thread confirmation at M12x1.5, and the rear axle nut clearance check that drives our square-only rule. At our fitment facility in Chandler, Arizona, the Element Wheels team measures directly on the physical platforms we support. We don't pull specs from manufacturer sheets the way most retailers do. The 37mm rear axle nut on the Kappa platform is the kind of detail that doesn't show up on a spec sheet but matters once you mount a wheel.
