some legacy sedans (i think two generations ago) had much bulkier rocker panels than others of that vintage - or other vintages. anybody know why this is? photo or a 2-gen-ago (white) with, and a 1-gen-ago (red) for comparison

 

Subaru call them "side spoilers" and are fitted depending upon the grade of model

 

Thanks.. i could not see any sub-model legacys (?legacies?) that did/did not have them. but i appreciate the quick response!
