What is the bolt pattern on a Chevy Chevette?
The Chevy Chevette uses a 4-on-100 millimeter bolt pattern (4x100).
For those restoring or upgrading a Chevette, here’s what this means, how it applies across years and markets, and what to check when sourcing wheels.
Pattern details
Learn the core geometry behind the Chevette’s wheel mounting system and why it matters when selecting wheels and adapters.
What 4x100 represents
The term 4x100 refers to four lug holes arranged on a circle with a diameter of 100 millimeters.
Center bore and fitment notes
Most Chevettes use a hub bore around 56.6 millimeters. When aftermarket wheels have a larger bore, hub-centric rings may be used to center the wheel on the hub and reduce run-out. If the bore is too small, you’ll need proper adapters or selecting wheels with the correct bore.
Key specs to confirm before buying wheels for a Chevette include the core dimensions that affect fitment and safety.
- Bolt pattern: 4 lug on a 100 millimeter circle (4x100).
- Center bore: typically 56.6 millimeters (2.23 inches).
- Market variations: while the 4x100 pattern is standard for most Chevettes and Opel/Vauxhall Kadett-derived models, verify exact specs for your year and market via the vehicle’s manual or wheel spec sheet.
Concluding: Always confirm with the wheel manufacturer and, if possible, measure the hub bore and lug nut requirements on your Chevette before purchasing aftermarket wheels.
Year and market notes
Chevette production spanned roughly 1976–1987 in North America, with Opel/Vauxhall Kadetts in Europe built on a common GM small-car platform. Across these variants, the four-lug, 100-mm bolt circle was the standard mounting pattern, though hub bore and minor fitment tolerances can vary by model year and market. When sourcing wheels, always double-check the exact specs for your exact vehicle configuration.
Summary
In short, the Chevy Chevette uses a 4x100 bolt pattern (4-on-100 mm) with a typical hub bore of about 56.6 mm. Confirm the center bore and lug nut requirements for your specific year and market, and consult wheel specifications or a specialist to ensure a safe, proper fit.
