Dynamic+ Lowering Springs were engineered and tested in-house at 034Motorsport to deliver superb ride quality and optimal handling performance. Designed as a true no-compromise solution,Dynamic+ Lowering Springs provide an aggressive yet functional stance, and reward drivers with precise vehicle control and OEM+ comfort levels. Dynamic+ Lowering Springs were thoroughly evaluated on the street and track on 034Motorsport's 8U Audi Q3 2.0T Development Vehicle, and by independent Audi enthusiasts before release. The selected spring rates, unique dual-rate spring design, and ride height are the culmination of months of testing - thousands of miles of commuting and countless track days - resulting in a lowering kit that is perfectly matched to the factory dampers.Each set of Dynamic+ Lowering Springs is manufactured at an ISO 9001 certified facility, and tested to 034Motorsport's exacting specifications to ensure they deliver unmatched levels of handling performance. These springs are the ideal suspension solution for the discerning Q3 owner who desires to lower their vehicle and enhance their driving experience.Why Are Dynamic+ Coil Spring Sleeves Needed?When designing 034Motorsport Dynamic+ Lowering Springs, we are not simply making a shorter spring. With lowering springs, the misconception is that the overall coil length is shorter. The spring itself is actually the same length as the OEM spring but they are designed with some of the coils in the spring closer together, which "stack" under weight, giving you the lowered ride height. Since the coils are physically closer to one another, when the suspension compresses and decompresses, the coils stack and rise.Coils stacking is engineered into the design of the majority of aftermarket lowering springs, aftermarket coilovers, and sometimes even OEM suspension. This depends largely on the design of the car during the engineering process.In some cases when these coils stack under heavy, they can create excess noise. For this reason, 034Motorsport offers Dynamic+ Coil Spring Sleeves to dampen the noise between coils. Not all Dynamic+ Lowering Springs will require these Coil Spring Sleeves, and for those that do, 034Motorsport includes a pair of Coil Spring Sleeves that are pre-installed in the appropriate location.Features:Lowering with Perfect, Functional Stance - No Reverse Rake!Improved Handling Performance & Chassis DynamicsReduced Body Roll & UndersteerSuperb Comfort & Ride QualityLightweight, High-Strength ConstructionShot Peened & PowdercoatedRide Height:Front - Approximately 1.57” (40mm) LowerRear - Approximately 1.57” (40mm) LowerEffective Spring Rates:Front - 166.2 Pounds/InchRear - 152 Pounds/Inch
