The Öhlins Dedicated Track coilover system for the 2008-2013 BMW M3 (E9X) is a shake-rig developed, track-validated suspension package tuned ready to run. It uses Öhlins Dual Flow Valve (DFV) monotube dampers with strengthened inverted front struts and aluminum-body rear shocks for reduced weight and better cooling. The kit ships with Swift-made springs (120 N/mm front, 180 N/mm rear) and is adjustable for both ride height and damping, lowering the car approximately 15mm front and 10mm rear at the recommended setup.
