Cadillac ELR Wheels and Rims

Cadillac ELR Aftermarket Wheel Fitment

The Cadillac ELR is the plug-in hybrid luxury coupe Cadillac sold for the 2014 and 2016 model years (Cadillac paused production through 2015 for a refresh). It rides on the GM Delta II Voltec platform shared with the Chevrolet Volt and uses Cadillac's re-engineered version of the suspension, brakes, and wheel hardware. Every ELR runs 5x115 with a 70.3mm hub bore, five lugs, M12x1.5 thread pitch, factory lug nuts. Factory wheel was a 20x8 forged aluminum design, all four corners. The ELR came from the factory with a front Brembo caliper package, which sets the brake clearance bar higher than a standard Cadillac coupe and is the detail to confirm when shopping aftermarket. Element Wheels catalogs the full ELR production run as one fitment row.

Find Your Cadillac ELR Configuration

The ELR ran two model years, 2014 and 2016, on the same platform with the same bolt pattern, hub bore, lug count, and thread pitch. Click through to see wheels and rims that fit your ELR.

The Cadillac ELR Bolt Pattern is 5x115

Every 2014-2016 Cadillac ELR runs 5x115 with a 70.3mm hub bore. Five lugs, M12x1.5 thread pitch, factory lug nuts. This is worth calling out because the Chevrolet Volt the ELR shares its Voltec platform with is 5x105, not 5x115. When Cadillac re-engineered the body and suspension for the ELR, it re-specced the wheel hardware to the 5x115 / 70.3mm hub spec used across the rest of the modern Cadillac sedan and coupe lineup. The ELR is on the Cadillac fitment family, not the Volt fitment family.

The ELR is 5x115 specifically. The 5x4.5 imperial nickname refers to 5x114.3 alone (114.3mm converts to 4.5 inches), not 5x115. The two patterns look similar on paper and a 5x114.3 wheel will technically thread onto 5x115 studs if the lugs are forced, but the stud spacing is off by 0.7mm at each lug position. That puts cumulative stress on the studs and is not safe. Confirm 5x115 before you order. A Chevrolet Volt wheel (5x105) is also not interchangeable with the ELR.

The 70.3mm hub bore is the GM hub spec carried across the modern Cadillac lineup (DeVille, Seville, DTS, El Dorado, STS, ELR). If your aftermarket wheel has a centerbore larger than 70.3mm (common on universal-fit wheels and on wheels originally specced for a different platform), it needs a hub centric ring to land hub-centric on the ELR hub.

Compare across the rest of the Cadillac lineup at our Cadillac wheels and rims hub. The ELR shares lug-and-hub fitment hardware (5x115 / 70.3mm) with several other modern Cadillac sedans and coupes, but the front Brembo brake package on the ELR sets a higher clearance bar than most of those siblings.

The ELR Wheel Window and the Front Brembo

The Element measured diameter window on the ELR runs 20 to 22 inch. The factory wheel was a 20 inch forged aluminum unit, all four corners. The 21 and 22 inch options in our measured window are the aftermarket upsize range. Width runs 8 to 9 inch on both axles. The catalog tags the ELR as non-staggered (FT=1), meaning a square setup all four corners is the correct approach.

The detail that most ELR shoppers should know: the ELR came from the factory with a front Brembo caliper package (catalog brake size 3 front, brake size 1 rear). The front Brembo is physically taller than a standard Cadillac caliper and demands a wheel barrel that clears the front brake hardware. Most modern forged or flow-formed 20 inch and larger wheels clear it fine, but a budget cast wheel with a tight inner barrel can interfere. We check this physically on every ELR fitment in our database, rather than reading the wheel manufacturer's spec sheet. The rear standard caliper is not a clearance issue.

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 Cadillac ELR Wheels

Element Wheels measures fitment on the platforms we sell wheels for, including the ELR. For the ELR that means clearance from the wheel to the fender on both axles, gap between the back of the wheel and the front suspension components, front Brembo caliper height confirmation (this one matters more on the ELR than on most Cadillac coupes because the Brembo is taller than a standard caliper), hub bore confirmation to the 70.3mm spec, lug seat geometry across the M12x1.5 thread pitch, and turning clearance with the wheel and tire installed at full lock. 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. That measurement work is what catches the front Brembo clearance call on the ELR and produces the published diameter and width windows above.
