What set of numbers/letters in the VIN would indicate a Super Sport?

 

the vin will indicate a body style like c/k truck wbody or jbody but this is no set trim character to my knowledge. modern w body ss version will have a specific engine code as the ss have the v8 engine. engine code is the eighth character.

 

I believe that you are looking for the platform (4th digit) and the platform series (5th digit).. If you are referring to an Impala SS it's a bit sketchy because my lists show three different series numbers for the Impala but only one designation as a LS..

Impalas and Monte Carlos are both W platform.. ( 4th & 5th) WB - Impala and Buick Regal LS; WF - Impala and Regal GS; WH - Impala LS; WW - Monte Carlo LS; WX - Monte Carlo SS

I know that isn't exactly what you asked for but maybe it is enough to get you headed in the right direction for finding your answer.

 

What about rpo codes in glove box?some code there should show a performance part
