I currently have Enkie Raijin 18" 9.5+15 with 265/35/19 and 285/35/18 and am getting the bronze superdeep 19" 11.5+30 but Jason is saying it may not fit the BBK so may have to go +15 or +10... Now I want 305 19", do i need to get a 30 or 35? 35 is available locally and cheap but if i HAVE to get 30 i can arranage it.. do you think if lowered it is needed? At the moment the wheels and tires are flush with rolled guards. No aftermaket camber tops.

Front I can get one 275/35/19 new locally for cheap ($170) but would have to get the other from tirerack ($228) - or go with 245/40/19 up front (locally $150) but im afraid ill understeer with too small tires and not have any sidewall protection on my rim... thoughts ?
