Welcome to wheel-it-fit wheel fitment calculator !

Want to know the exact wheel size for your car ?

Better than a wheel size guide !

Wheel size guides are subjective because many things can come into play and unlike generic calculators, Wheel-it-fit uses the actual data from each car to make measurements very accurate. This calculator is unique because it simulates the suspension as well as the natural camber generated by the mechanical parts.

Mustang, FRS / BRZ / 86, Miata, 370z, WRX and more !
