Now that fitment is sorted, how do you choose the right wheels? Part 2 of our beginner JDM mod series looks at rims, wheel construction, sizing, Japanese brands like RAYS, Work, Enkei, SSR, ADVAN, and Watanabe, plus daily, drift, show, and performance builds. Fitment tells you what can fit. Purpose tells you what makes sense.

Before you buy wheels, chase stance, or start dreaming about the perfect first mod, you need to understand fitment. This opening article in the series breaks down the basics of how wheels and tires actually sit on a car — from offset and tire size to tucked, flush, poke, and stance fitment. Because before you can know what you want to do to your car, you need to know what your car can actually handle first.
