Either this is not ET11 or it is not 8" bead width, it sticks out too far for that spec to be correct
stock SC rear fit is either 7ET23.3 or 8ET10.6, if it was an 8ET11 it would sit a tad more inboard than a stock 8ET10.6
just to have some idea of how they fit compared to 7ET23.3
8ET10.6 sits 25.4mm more outboard but still w/ plenty of lip clearance
9ET15 sits 33.7mm more outboard but still w/ plenty of clearance
9.5ET19 sits 36mm more outboard and will need some work to clear the lip w 275 tires less w/ 255 tires
