Racing surfaces with buggies in mind.....
 

I would like to know where carpet sits in relation to grip levels compared to other surfaces - astro, wet astro, cork, wood, clay, dirt....

Can someone please list above surfaces including others missed with greatest grip levels listed first?

Thanks.

Depends on the grade and type of carpet.

Carpet is generally thought of as high grip, which when running on nice Primafelt generally is.

At the last EOS, for example, they had used some cheap "exhibition carpet", and the grip was interesting. Sometimes (at the start of the meeting) it bit you with high grip, but mostly it was slidey and not grippy at all. Off the racing line with the loose fluff and rubber it was as slippy as wet astro or gym floor.

Your grip flow in the list isn't as simple as that. Dirt tracks can be super slippy, but with moisture and/sugar they can be very grippy indeed.
Polished wood or rubber gym floors can be nightmare slippy, but washed/brushed and free of loose dust in a warm room they can be classed as much higher grip then when cold and dusty.
As in my first example, carpet can be variable grip level also, like astro, if its the butchers astro can be very low traction compared with the carpet like stuff.
