Eibach Cadillac CT5-V Blackwing - Special Edition Pro-Kit - E10-203-004-01-22

The Eibach Special Edition Pro-Kit (E10-203-004-01-22) is a purpose-built set of performance lowering springs engineered specifically for the Cadillac CT5-V Blackwing — one of the most capable American performance sedans ever built. If you're looking to sharpen the already impressive factory handling, eliminate excess body roll, and give your Blackwing an aggressive, planted stance, these Eibach PRO-KIT springs are the direct-fit upgrade to start with.

Key Features & Benefits

• Expected 0.7-Inch (17.8 mm) Drop: Lowers the CT5-V Blackwing's center of gravity for a visibly more aggressive stance and reduced body roll during spirited driving — without requiring a full coilover conversion.
• Progressive Spring Design: Eibach's progressive-rate spring technology provides compliant, controlled compliance over everyday bumps and progressively firmer support under hard cornering — so you don't sacrifice daily-driver comfort for performance gains.
• High-Performance Handling: Lower center of gravity helps the Blackwing stop quicker and corner faster, complementing the factory Magnetic Ride Control and Brembo braking system rather than fighting them.
• Tested with Factory Dampers: Eibach notes these springs are tested with OEM dampers, meaning they are designed to work with the CT5-V Blackwing's stock shock absorbers — no simultaneous damper replacement is required.
• Five-Year Warranty: Eibach backs the Pro-Kit with a 5-year warranty covering factory defects in material and workmanship under normal use and operating conditions.
• Set of Four Springs: Complete front and rear set included — everything needed to lower all four corners evenly for balanced, predictable handling.
• Premium Eibach Quality: The PRO-KIT is Eibach's flagship street performance spring line, trusted by enthusiasts and motorsports competitors alike for reliable, repeatable performance.

Frequently Asked Questions

Q: Will these springs work with my factory shocks and Magnetic Ride Control?
A: Yes. Eibach explicitly states these springs are tested with factory dampers, meaning they are engineered to pair with the CT5-V Blackwing's OEM suspension components. You do not need to replace your factory shocks or dampers to install the Pro-Kit.

Q: How much will my CT5-V Blackwing drop with these springs?
A: The expected drop is 0.7 inch (17.8 mm). Keep in mind actual ride height can vary slightly depending on vehicle load, factory suspension tolerances, and current suspension condition.

Q: Does this kit include all four springs, or do I need to buy front and rear separately?
A: This is a complete set of four springs — both front and rear are included in one purchase. No separate kits are needed.

Q: What does Eibach's warranty cover?
A: Eibach provides a 5-year warranty covering factory defects in material and workmanship (excluding coatings) when the springs are used on passenger cars under normal use and operating conditions.
