The 8 helmets mentioned in the Grassroots Motorsports article represent examples of the various price points, not implied that they are any better than other helmets. The reviews on each helmet mentions Shell, About, Comfort & Visibility, Quality & Details and Extras

Features are grouped: Weight, Comfort, Air, Style, Vision

Some of the article comments:

* Some helmets are specifically designed to help manage the wind buffering and lift experience by drivers of open cockpit cars

* Some helmets offer a larger wider eye port designed to specifically accommodate glasses

* Road course drivers may also prefer the wider eye port to enlarge their field of vision, since restraint systems can restrict lateral head motion

* Need for air intakes designed to keep sedan drivers cool and comfortable

* Pre-drilled attachment points for a head and neck support system
