Product Details
These H&R RS ID lowering springs fit the 2017-2019 Porsche 911 GT3 (991) w/PASM. They will enhance this fantastic performance vehicle. The stock Porsche 911 GT3 has threaded shocks for fine-tuning ride height, but some enthusiasts would like to lower their GT3 a little more from factory ride height. H&R ride development engineers have been listening and designed a set of RS ID springs for reduced fender well gap. H&R RS ID Springs are a combination of our 60mm ID Race Springs to lower the GT3.
H&R RS ID Springs for the GT3 lower approximately .75 to 1.5 inches front and .75 to 1.4 inches rear. Lowering the vehicle's center of gravity improves handling and creates a sleek European look.
Every spring produced by H&R comes from the H&R ISO 9001 certified engineering and manufacturing facility in Germany. All H&R springs are produced from a special 54SiCr6 spring steel, which has strength rated at 290,000 psi resulting in unrivaled tensile strength and resiliency.
