yupppp
ive done alot of looking into for the s13 chasis and what ive basically come up with is 17 all around (or 18 in rear) minimum of 9" wide with a zero offset or spacers to make it a zero offset, then you can get a plus offset if your running wider than 9"
thats for mild work done to the body, then you can go more negative the more widebody you wanna run! boo yaa
