Performance Springs

The Dinan Performance Spring Set is engineered to transform the stance and improve the handling of your F22 M235i/M240i (RWD) vehicles. These springs offer greater control over body roll due to their precisely calibrated rates, while also lowering the vehicle by 1/2" in the front and a full 1" in the rear, contributing to improved suspension geometry and a more aggressive appearance. The front springs feature a 10% increase in stiffness, and the rear springs boast a 27% increase. The improved grip during high-speed driving and more responsive steering at all speeds are key benefits, enhancing driver confidence and the overall driving experience. It is highly recommended to purchase and install the Dinan springs in conjunction with the corresponding Ride Quality and Handling Kit (D193-2201) to achieve the advertised ride height, performance, and ride quality. While not explicitly mandatory, failing to use the matching kit may result in less favorable outcomes, such as poor ride quality and improper handling traits. Dinan will honor its warranty for product defects, but claims related to improper handling or ride quality due to the omission of the corresponding handling kit will not be warranted.
