I have the Willwood BBK from 2JR, and I have 17 x 7 ET42 4 x 108 OZ Ultraleggera wheels. I am looking to get a set of 16" wheels, as there appear to be more tire choices. I'm concerned that the 16" wheels will not fit with the big rotors that come with the Wilwood BBK. Anyone has 16" wheels with Willwoods on them. If so, what tire size did you fit on these? Thanks. I'm also looking at getting BCC coilovers from 2JR, and dropping the FiST about 1".
