don't know what kind of KART racing your speaking of ( go -karts,sprint karts etc...)...anyhow most of these kart classes have weight restrictions Minimums( Kart and Driver)..if this is the case..i do not see where CM vs MS would make any difference....Cm moly is a lighter and tougher metal
can you tell us where the competitiors think he is getting the edge over them if it was a cm chassis ?...just curious
