Eibach Sportline Kit for 2011-2014 Ford Mustang Convertible 3.7L V6/5.0L V8

The Eibach Sportline Kit consists of performance lowering springs designed specifically for 2011-2014 Ford Mustang Convertibles with 3.7L V6 or 5.0L V8 engines. It fits Base and Boss 302 submodels, dropping ride height 1.4 inches front and 1.2 inches rear to sharpen handling, reduce body roll, and create a lowered stance. Drivers gain improved steering response and road contact while retaining comfort for daily use.

Key Features

  • Precise Lowering: Front 35mm (1.4in), rear 30mm (1.2in) – achieves balanced drop for street-driven Mustangs without excessive harshness.
  • Progressive Spring Rates: Delivers smooth initial compression then firm resistance for confident cornering and stability.
  • High-Strength Steel Construction: Forged from chromium-silicon SAE 5160 alloy, shot-peened and tempered for fatigue resistance over high mileage.
  • Durable Finish: Epoxy powder coat resists corrosion and road salt for lasting protection.
  • Million Mile Warranty: Covers defects and sagging, ensuring long-term performance reliability.

Product Notes

  • Confirm tire and wheel clearance before installation; may require minor fender rolling on some setups.
  • Pair with Eibach shocks or struts for full Pro-System benefits.
  • Ships as complete front/rear spring set; standard ground freight.

Installation Notes

  • Professional installation recommended.
  • Direct bolt-on replacement for OEM coil springs; no cutting or welding needed.
