The following DOES NOT apply to 100% of the cases, but it does happen enough that I avoid recommending wheel spacers just to accomplish "the look".. Keep in mind that old adage --- You can have it cheap, good, and fast.. Pick any 2 as you can't have all three.. From reading your original post you want it cheap and fast???? The question begs to be asked--- Why would you not want a good job????
When you add those spacers, you'll increase the load/leverage on wheel bearings and axle bearings - leading to premature failure... You'll change the scrub radius on the front tires - leading to alignment issues and increased tire wear.. When you come here and ask for a solution to those problems, the correct answer will be -------
Drum roll please...
Remove those spacers....
