Buick Century Wheels and Rims

Buick Century Aftermarket Wheel Fitment

The Buick Century is the mid-size sedan Buick built in its final form from 1997 through 2005 on the GM W-body platform. Element Wheels stocks direct fitment for the 1997-2005 W-body Century. The bolt pattern is 5x115 with a 70.3mm hub bore across every W-body Century model year, with M12x1.5 thread pitch and conical seat lug nuts. Fitment is square front to rear by default and there is no Brembo or upgraded factory caliper variant to track. The catalog runs from 15 inch through 20 inch diameter on the Century. The Century nameplate ran continuously from 1973 through 2005 across multiple platforms but the 1997-2005 W-body is the generation Element supports for aftermarket fitment.

The Buick Century Bolt Pattern

The 1997-2005 W-body Century runs the 5x115 bolt pattern with a 70.3mm hub bore. Lug count is 5. Thread pitch is M12x1.5. Lug type is conical seat (lug nuts, not bolts). This 5x115 / 70.3mm spec is shared across the W-body family of GM full-size and mid-size sedans, which includes the W-body Regal (1997-2004) and the W-body Park Avenue era of the Buick lineup, and on the Chevrolet and Pontiac side covers the Impala (2000-2005), the Monte Carlo (2000-2007), the Grand Prix (1997-2008), and the Bonneville (2000-2005). The bolt-on architecture lines up across the W-body lineup, though brake clearance and offset windows differ by model.

A note on imperial nicknames. The 5x4.5 imperial label refers to 5x114.3 alone. 114.3mm equals exactly 4.5 inches, which is where the imperial name comes from. The Century is 5x115 specifically. It is not 5x114.3, and the imperial 5x4.5 nickname does not apply. The 5x115 and 5x114.3 bolt circles differ by only 0.7mm but the studs do not seat correctly across patterns and the wheels do not safely interchange. Force-fitting a 5x114.3 wheel onto a Century hub puts stress on the studs that will eventually fail. Confirm the 5x115 pattern before ordering. Compare against the rest of the Buick lineup at our Buick wheels and rims hub.

Why the W-Body Century Is the Generation Element Supports

Buick sold a Century nameplate continuously from 1973 through 2005 across multiple platforms. The 1973-1981 Century ran on the GM A-body platform as a rear wheel drive mid-size. The 1982-1996 Century moved to the GM A-body front wheel drive platform after GM transitioned its mid-size lineup. The 1997-2005 Century is the final generation, built on the GM W-body platform and sharing its underpinnings with the W-body Regal, Grand Prix, Impala, and Monte Carlo of the same era. The W-body generation is the only Century generation in the Element catalog, so aftermarket fitment on this page is scoped to 1997-2005.

Fitment on the W-body Century is straightforward by Buick standards. One platform, one bolt pattern, one hub bore, no Brembo variant, no AWD complication. The 3.1L V6 was standard across most of the production run. Buick discontinued the Century after the 2005 model year and the slot was eventually filled by the LaCrosse, which launched on a refreshed W-body in 2005 and moved up the Buick range from there.

How We Confirm Fitment on Buick Century Wheels

Element Wheels measures fitment on the platforms we sell wheels for, including the 1997-2005 Century. For the Century that means clearance from the wheel to the fender, gap between the back of the wheel and the suspension, brake caliper height, hub protrusion past the mounting surface, lug seat depth, and turning clearance front and rear with 17 to 20 inch wheels installed. At our fitment facility in Chandler, Arizona, the Element Wheels team measures directly on the physical platforms we support. The Century 70.3mm hub bore matches the rest of the W-body family so hub centric ring sizing is straightforward. We do not pull specs from manufacturer sheets the way most retailers do.

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.
