The standard suspension works extremely well with quick, responsive steering. Overall, the 300M feels like a refined luxury sports touring sedan, even if noise and vibration are not down to Lexus levels. A small amount of wind noise can be heard, and a bit of road vibration comes through.
The optional handling package includes firmer strut damping, taller rear jounce bumpers, a firmer feeling steering gear, Michelin HX all-season performance tires, high-performance brake linings, stiffer front brake calipers and externally vented brake rotors. The handling suspension is tuned for a more controlled ride, sharper steering response, improved stability in transient maneuvers and increased cornering grip. The brakes, shared with the 300M Special, are designed to increase stopping ability, enhance pedal feel and resist fade in hard use. Next Page
