Product Description

The BMR Suspension SP027R Lowering Spring Kit is a performance-oriented suspension upgrade designed specifically for the Ford Mustang from 1979 through 2004. These springs deliver a consistent 1-inch drop at both front and rear, giving your Mustang a classic lowered stance and improved aerodynamic balance while enhancing handling dynamics on street and back-road driving. Crafted from high-tensile chrome silicon spring steel, each spring is cold wound on a CNC coiling machine, stress-relieved, shot-peened, and computer tested to ensure precision and longevity.

With balanced spring rates (~525 lb/in front and ~235 lb/in rear), the SP027R springs help reduce body roll in corners, flatten out weight transfer under acceleration or braking, and maintain a smooth, controlled ride quality for daily driving. The set includes front and rear springs with a durable red powdercoat finish for long-lasting corrosion resistance. While broadly compatible across Mustang trims, note that these springs are *not* suitable for 1999-2004 Ford Mustangs equipped with independent rear suspension found on certain Cobra models; always verify fitment for your specific year and submodel before installation.
