Pro Kit 09-15 Cadillac CTS-V

The Pro Kit 09-15 Cadillac CTS-V suspension spring kit by EIBACH is engineered for serious performance enthusiasts who demand a factory-quality foundation for their aggressive V-series platform. If you're building a CTS-V that will see track duty, aggressive street driving, or want to dial in the chassis geometry without sacrificing daily usability, this is the professional-grade solution. EIBACH's Pro Kit bridges the gap between stock compliance and full race suspension, giving you the lowering and stiffness benefits without the harshness of ultra-competitive setups.

This kit delivers a moderate spring rate increase paired with progressive spring geometry that maintains ride quality under normal conditions while tightening body roll during hard cornering and braking events. EIBACH's precision manufacturing ensures consistent preload and rate across all four corners, critical for vehicle dynamics tuning on a 6.2L supercharged platform carrying substantial curb weight. The kit's geometry is specifically calibrated for the 09-15 CTS-V's independent double-wishbone front and five-link independent rear suspension, preserving factory bump stops and allowing seamless integration with OEM shocks or aftermarket dampers. Typical drop sits around 1.0 to 1.2 inches, improving center of gravity and stance while keeping suspension travel functional.

Owners upgrading from stock springs find the Pro Kit transforms steering response and reduces understeer tendencies without introducing excessive NVH into the cabin—essential for a luxury sport sedan. Installation requires full compression and controlled spring removal; jack stands and a proper compressor are mandatory for safe handling of high-rate springs under tension. This kit pairs exceptionally well with Bilstein or Öhlins dampers and works cleanly with factory anti-roll bars, making it ideal for track-focused builds or comprehensive chassis refresh packages on 2009–2015 CTS-V models.
