I wonder what the 305 tires are? Make and model. Performance is identical as the earlier Hellcats when fitted with after market drag radials. EDIT: Found my answers... · Pirelli All Season Performance Tires on 11" wheels - Standard · No mention of forged wheels and No wheel options. · front track grows by 1.6 inches and the rear track by two inches even. EDIT2: Now it would be nice to know how/why the track increased so much. It certainly wasn't only for the extra tire width. Did the mounting hubs actually increase or was it all by wheel offset
I think wheel offset, as with my 305's on 10 inch rims the is about 1/8" clearance between the sidewall of the tire and inner rear fender liner at the front part of the tire.
