Audi B9 A4/S4 EMD Auto eMMOTION Springs
After our longest development cycle to date, we are pleased to release our lowering springs for the B9 A4/S4 platform. Through months of testing and thousands of miles logged, we have created what we feel is the best lowering spring option for daily driven vehicles. As with any of our lowering spring options, the goal with our B9 lowering springs is to keep ride quality as close to stock as possible, while adding an OEM+ level of drop.
Having a B9 in our development fleet allowed us to spend a lot of seat time in the vehicle. This was especially advantageous in our development process, as we were able to log many miles over various surfaces and road imperfections. We felt that the car offered a very comfortable ride in stock form, and this was something that we did not want to sacrifice. With our lowering springs, we feel that we have found the balance between adding some sportiness while still keeping the ride quality that you expect from a premium Audi.
Each spring set is 100% made in the USA exclusively for Emmanuele Design. The springs are made of high tensile chrome silicon and each unit is shot peened, pre-set and 100% tested to ensure all the critical dimensions and rate/loads are within tolerance. Each spring is zinc primered for increased corrosion resistance, then powder coated with a gloss black finish for an OEM appearance. The use of high tensile chrome silicon, as opposed to typical commercial grade chrome silicon, allows us to create a lighter spring that can sustain repeated deflection without deformation. High tensile chrome silicone will typically have thinner coil diameters that are spaced further apart, when compared to commercial chrome silicon.
