Darth Cooper is an '04 MINI with Sport Suspension+, Rspeed Exhaust, K&N filter, 16" X 6.5 X 45mm offset SSR rims shod with 205/55-R16 Falken Azenis Sport st-215s. Since these are no longer available I would very much like to replace them with something from the new lineup of RT-615's I am partial to the 215/45-16's but I am concerned about Rim fit, and Suspension clearances. Anyone out there done this successfully?
