Rubbing?
 

If I drop my civic 1.75 inches with 18" inch rims with a +45 offset will they rub the fender?

i have my coilovers about 3 inches down and i have 18 inch wheels, and it doesnt rub.you should be fine

n00b question: whats the offset? and fenders are the panel between the front and door right? :rolleyes:

offset refers to the position of the wheel as it mounts on the hub. a positive offset (+) will position the wheel going inwards to the car. based on my experience, 5th and 6th gen civics require higher than a +38mm offset to in order for the wheel not to rub.

fenders, in this case is the outer edge of the tirewell.
