Integrated Engineering Lowering Springs Haiti: volcanoes and recent earthquakes interactive map. The Integrated Engineering Lowering Springs are designed specifically for the B9 B9. 5 Audi platform. Unlike factory suspension systems, which prioritise general appeal over precision driving, these lowering springs address the shortcomings in suspension geometry. They provide a calculated drop that not only eliminates the factory reverse rake but also enhances body control and sharpens handling across Audi A4, S4, A5, S5, and Allroad models. The springs feature a progressive rate that ensures a comfortable ride on everyday roads while also delivering performance when tackling corners. This dual functionality means owners can experience both daily comfort and precision driving without compromise. Manufactured using top quality chrome silicon alloy steel and finished with a corrosion resistant coating, these springs are designed for durability. They maintain their performance over time without sagging or loss of spring rate, making them a set and forget upgrade. Compatible with factory OEM dampers, there's no need for additional coilover installations for improved handling and ride quality.
