The new Hurst Olds shared with all 1973 GM A body cars, the most extensive redesign in their 10-year history The chassis was as new as the bodies -Wheelbase dimensions were a sporty 112 inches for coupes and 116 inches for sedans and station wagons on an all-new sturdier perimeter frame with increased front and rear suspension travel, larger 8½ inch rear axle, wider 6-inch wheel rim width, refined rear control arm bushings and new shock absorber location, new body mounts and improved front suspension geometry - The left wheel was adjusted to have slightly more positive camber than the right which resulted in a more uniform and stable steering feel on high-crown road surfaces while maintaining excellent freeway cruise stability. Clearances for spring travel were improved for a smoother ride over all types of surfaces; the coil springs at each wheel were computer-selected to match the individual car's weight. Power brakes with front disc brake calipers were now standard on all '73 Cutlasses.
