Factory Performance

- Braking Enhancements⁚ Upgrading the braking system was essential for improved stopping power, especially after engine modifications. Larger rotors, high-performance calipers, and upgraded brake lines were common upgrades.
- Drivetrain Modifications⁚ Modifications to the transmission and rear differential were often made to handle the increased power and torque. This could include stronger axles, limited-slip differentials, and performance-oriented transmissions.
The B-body platform offered a solid foundation for performance modifications, allowing enthusiasts to create powerful and capable machines that could be enjoyed on the street, track, or drag strip. The enduring popularity of these cars can be attributed in part to their versatility and potential for customization.
