What is the bolt pattern on a Toyota Celica gt4?
The bolt pattern is 5x100, meaning five lug holes on a 100 mm bolt circle, with a center bore of 60.1 mm. This pattern is standard across the Celica GT-Four lineage, but you should still verify bore size and offset when selecting wheels.
This article explains what that means for wheel compatibility, covers the GT-Four generations (ST165, ST185, ST205), and outlines practical checks to ensure a proper fit for replacement or aftermarket wheels.
Bolt pattern basics
Before listing the core specifications, here are the essential details you need to know about the Celica GT-Four’s wheel mounting.
- Pattern: 5 lug holes
- Bolt circle (pitch circle): 100 mm (5x100)
- Center bore: 60.1 mm
- Lug thread size: M12x1.5
- Typical wheel offset range: roughly ET35–ET45, depending on wheel width and variant
In practice, most wheels labeled for 5x100 will bolt onto a Celica GT-Four, but matching the center bore and offset is crucial for a proper fit and to avoid vibration or clearance issues.
Generational consistency and compatibility
Across the main GT-Four generations, Toyota kept the 5x100 bolt pattern, which simplifies wheel choices when upgrading or replacing rims. The key variants commonly discussed are ST165, ST185, and ST205, all of which use the same basic lug arrangement.
- ST165 (late 1980s to early 1990s): 5x100, 60.1 mm bore
- ST185 (early to mid-1990s): 5x100, 60.1 mm bore
- ST205 (mid to late 1990s): 5x100, 60.1 mm bore
Conclusion: The GT-Four line maintains a consistent 5x100 bolt pattern across its major generations, which helps with wheel availability. Always verify the exact bore size and your chosen wheel’s offset to ensure a proper, safe fit.
Summary
In short, the Toyota Celica GT-Four uses a 5x100 bolt pattern with a 60.1 mm center bore across its main generations (ST165, ST185, ST205). When buying wheels, confirm both bore size and offset for your specific car, and consider hub-centric rings if the wheel bore is larger than 60.1 mm. For best results, consult a wheel and tire professional or reference your vehicle’s manual or a trusted parts guide before purchasing wheels.
