Hi,
Don't believe 320///'AMG' spec has uprated brakes....AMG pack outlined below:
"AMG SPORT PACKAGE option newly available for 2001-2002 model year ML's. This package includes: 17" Six Spoke wheels with performance tires, Chrome exhaust tip, and Aerodynamic body styling with integrated foglamps. In 2002, new side-view mirrors with integral turn signals debut, as do clear lens headlights, chrome grille accents, front fog lamps and revised front and rear bumpers. Inside the cabin, vents are added to the rear of the console and electronic push buttons replace the old twist knobs on the climate control system.
The vehicle is also equipped with the Convenience package, Luxury Package, roof rack, power windows, locks, and moonroof, Bose sound system with integrated CD Changer, Keyless Entry Security System, front, side, rear, and head protection curtain airbags, wood dash and interior trim. Touch Shift automanual transmission. Dual-stage front airbags know when to deploy with partial force or full force. All models also feature expanded off-road capabilities with new downhill traction control and a new crawling mode for very slow and steep off-roading."
Cheers,
