Mercedes made this change not only to cut costs but also to reduce complaints about brake squeal from customers not used to high performance brakes.) • Additional engine oil cooler (behind right-hand bumper vents) • Lowered/stiffened suspension (springs, shocks, sway bars) • 18-inch alloy wheels with 225/40 front and 245/35 rear tyres. • AMG body kit, with distinctive gills in front bumpers • Chrome-accented fog lights • Napa leather interior • Quad exhaust • Smoked taillights and
