Optimize. This is the perfect balance of handling, comfort, and value for your C5 Corvette. This kit delivers on years of development and testing so you can reap the benefits of high-performance handling without making your Corvette too low. This is a great choice for frequently street-driven 'Vettes. Better handling. The bolt set lowers your Corvette's center of gravity, reducing squat during acceleration, body roll in corners, and excessive nose-dive under braking.

To achieve optimum handling, we recommends an alignment after installation. Track proven.
