Tires make a huge difference also. Sidewall dimensions, etc.
Design of the wheel definitely can make a wheel look smaller / larger than what it is.
You have to factor in what you want the result to be and pick the parts that will get closest to that when combined.
Don't know much about spacers, but I have a set and hesitant to install, because of torque value conflicts.
What what value did you torque the spacers onto the hub and what torque value did you torque the wheels to the spacers?
Ford says 150 lb ft of torque for wheels to hub. Spacer...
Looks killer!!! Lowered? More specifics on wheel size / offsets please. Got some side profile pics showing how close to the fender they sit? Any rubbing issues?
