hey guys, i have a few q's

im thinking about putting some lowering springs on my daily beater (it has some wicked reverse rake going on, oem)
i usually run coils, and ive only had 1 spring setup on an s13, oem wheels.

now this car is an s14, springs in question will be megans

im planning on some cheap wheel/tire setup...nothing killer as this is a beat around junk a** car, which i was going to build and as things usually happen...now i cant. so what i spend on it will be very minimal.
probably some cheap a** used mustang rep wheels or somthing
will these rub? 18x9 in the 20's

any experience with offset/width with these springs....basically how much can i get away with here?

maybe stupid question but ive always just replaced with coils in the past. now "minimally employed" i cant do it...but i gotta rid it of this backwards a** rake man.

nobody? well damn.
