BMR Performance Lowering Springs Set - 1.5" Drop - Red (SP035R) - 1978-1987 GM G-Body
Transform the stance and dynamic capabilities of your classic GM cruiser with the Performance Lowering Springs Set (SP035R) from BMR Suspension. Specifically engineered for 1978-1987 GM G-Body platforms, this complete set of four springs provides a balanced 1.5-inch drop front and rear. By swapping out worn, saggy factory coils, this kit eliminates unsightly fender gap and lowers your vehicle's center of gravity. This translates directly to a highly stable, flat-cornering chassis that drastically cuts down on body roll and brake dive, delivering modern performance handling without harsh ride characteristics during street driving.
Every spring in the SP035R kit is meticulously crafted from premium high-tensile chrome silicon spring wire and cold-wound on advanced CNC coiling machinery to ensure absolute left-to-right uniformity. BMR implements a rigorous manufacturing regimen to guarantee elite durability: each coil is pre-compressed solid twice at the factory to set its permanent height, stress-relieved at 750°F, and shot-peened to eliminate surface tensile forces. The front springs utilize a firm 620 lb/in linear rate for immediate steering response and front-end support. The rear springs feature an engineered 100-200 lb/in dual-rate design, providing soft compliance over road imperfections that transitions to firm cornering control under load. Finished in a high-durability red powder coat and 100% computer load-tested, this kit includes a lifetime warranty against spring sag.
