Always seeking to enhance the Hyundai Genesis driving experience, Hyundai engineers have made further refinements to the 3.8 and 4.6 model suspension damping calibrations. These precise adjustments serve to minimize the traditional compromises between handling precision and ride comfort. In addition, body roll control for the 3.8 model is enhanced, with the rear stabilizer bar diameter increasing from 17 mm to 18 mm. Braking is also improved on both the 3.8 and 4.6 models; the 3.8 model front rotor size increases from 12.6 inches to 13.0 inches, while adding by higher performance 4-piston brake calipers, and the 4.6 model front brake rotors increase from 13.0 inches to 13.6 inches for greater fade resistance.
