I'm in queue at barbers atm so thought I would dig for you.
From what I've found 9j is a pretty iffy width. With an et of 45 u might get away with rolled arches on the front depending on tyres. Tears should be ok. A lot of staggered fitments run 9.5j on rear.
I have 9.5j all round but cheated and used some bolt on arches
