Springs are the easiest and most cost effective way to improve your handling, get a more aggressive rake, and give your vehicle a more attractive stance. We do recommend replacing your shocks and struts at the same time with either Bilstein or Koni dampers.
Using a linear design (similar to OEM) with unique spring rates, Emmanuele Design's lowering springs are properly matched to the factory dampers, ensuring a ride quality that is slightly stiffer than stock, but predictable in nature. A progressive spring will typically be softer at light loads, then dramatically stiffen as compression increases. This makes it very hard to match dampening, and creates the bouncy feeling over light bumps. The linear design of these springs have a consistent rate as the spring sees higher load. On light bumps, it will allow the chassis to follow the road well (minimizing the bouncy feeling), while under heavy compression it will stiffen to prevent bottoming out. In our experience, this creates a much better overall ride quality. Compatible with adaptive suspension. Lowering of 1.3" front and .3" rear.

AST Suspension Lowering Springs for the 2013+ BMW i3 will lower that center of gravity without giving in a lot of the comfort you are used to with the OEM springs. The lowering springs are a direct replacement of the OEM springs and have been developed especially for each specific vehicle. Made out of the best material on the best Wafios coiling machines available. AST Suspension Lowering Springs are manufactured from a premium high tensile chromium-silicone wire which is handpicked by AST engineers for its quality and metal consistency. Each spring is cold wound and then heat treated to increase hardness and reduce internal stresses present after winding. Each spring is then individually shot peened, phosphate treated and then powder coated to outlast even the life of the vehicle.
