Here's how it works:

CAR
OEM Specs

Tell us what size the car's OEM wheels and tires are. For advanced setups, you can also consider properties like your car's wheelbase.

SETUP
New Specs

Tell us what your new setup will look like. Smaller wheels for the winter? A staggered configuration for the track? Larger tires for mudding? Or maybe just as close to OEM as you can find for your classic car?

CALCULATOR
Comparison

Finally, pick your new setup. Play around with values like the offset, wheel width and tire size. We'll show you how it compares to your OEM setup to give you an idea of how it'll fit on your car in real-time.
