Bridgestone/Firestone's Praxis Advanced Suspensions unit has designed an air suspension system for the E-46 BMW M3.
The aftermarket system lets drivers select the height, spring rate and damping "to suit their mood or the driving environment," say Bridgestone/Firestone officials.
Praxis also offers adjustable air suspension systems for 3-Series BMWs and Subaru WRX models.
Praxis is made by Bridgestone Firestone Vehicle Systems, an operating unit of BFS Diversified Products LLC.
