Im running 17x9 +20 offset at all 4 wheels. The car is as low as I can get it on the coils. The rear fenders are rolled only slightly to get the car as low as possible. I thought running the same offset and width would look like shit all around, but it came out perfect. My s13 has an sr so theres no need for wide tires up front, I just wanted an aggressive offset and figured why not go wide.
