Separate things. i see quite a few people use nomex suits for karting, however i cant say that i would want to be in one sliding along asphalt, whereas a CIK/FIA tested karting suit is checked for abrasion resistance and usually made of cordura. also a kart suit will probably feel lighter and less hot on a hot day as nomex is an insulator. shoes and gloves should be fine for karting and car use.
