wheel fitment with Z32's

[Marteh]

hey folks looking to get some info here, done a quick search could only find wheels for sale or the wheel fitment thread which didn't really give me what i was after.

I have some SSR Professor Sp1's with these specs
18x9 ET+24

wanting to fit these to my 180sx but im also wanting to fit them with my z32 calipers but Ive noticed there is some clearance issues and the wheels keeps fouling the caliper.

what spacer would be needed to clear them and will it still fit under the Metal arch?

pics of fitment would be a great help as well.

thank you.
